• How to define RequestMapping prioritization

  - by James Skidmore

  I have a situation where I need the following RequestMapping: @RequestMapping(value={"/{section}"}) ...method implementation here... @RequestMapping(value={"/support"}) ...method implementation here... There is an obvious conflict. My hope was that Spring would resolve this automatically and map /support to the second method, and everything else to the first, but it instead maps /support to the first method. How can I tell Spring to allow an explicit RequestMapping to override a RequestMapping with a PathVariable in the same place? (Edit - this is simplified, I know that having those two RequestMapping alone wouldn't make much sense)

• JPA hibernate OneToOne mapping

  - by Stupidfrog

  enviroment: hibernate 4.1.6.final spring 3.1.2.release spring jpa 1.1.0.release postgresql 9.1-901-1.jdbc4 there is 2 table public A { private Long id; private Long name; } public B { private Long id; private Long table_a_id; } the A.id and B.id is sequential, unique , but no related.(means they are separately id for their own table). how to do mapping? i have tried some method, however the result is not i wanted, because it bind wrong. for example: public A { .... @OneToOne @JoinColumn(name = "id") private B table_b } public B { ... @JsonIgnore @OneToOne(mappedBy = "table_b") private A table_a; } when i query A the result is { "id":5, "table_b":{ "id":5, "table_a_id":4 } } obviously the data join by using their id but not joining using table_a_id. what i expect is { "id":4, "table_b":{ "id":5, "table_a_id":4 } } so can somebody teach me that, how to map this 2 table by using table b table_a_id(foregin key)

• Spring transactions not committing

  - by Clinton Bosch

  I am struggling to get my spring managed transactions to commit, could someone please spot what I have done wrong. All my tables are mysql InnonDB tables. My RemoteServiceServlet (GWT) is as follows: public class TrainTrackServiceImpl extends RemoteServiceServlet implements TrainTrackService { @Autowired private DAO dao; @Override public void init(ServletConfig config) throws ServletException { super.init(config); WebApplicationContext ctx = WebApplicationContextUtils.getRequiredWebApplicationContext(config.getServletContext()); AutowireCapableBeanFactory beanFactory = ctx.getAutowireCapableBeanFactory(); beanFactory.autowireBean(this); } @Transactional(propagation= Propagation.REQUIRED, rollbackFor=Exception.class) public UserDTO createUser(String firstName, String lastName, String idNumber, String cellPhone, String email, int merchantId) { User user = new User(); user.setFirstName(firstName); user.setLastName(lastName); user.setIdNumber(idNumber); user.setCellphone(cellPhone); user.setEmail(email); user.setDateCreated(new Date()); Merchant merchant = (Merchant) dao.find(Merchant.class, merchantId); if (merchant != null) { user.setMerchant(merchant); } // Save the user. dao.saveOrUpdate(user); UserDTO dto = new UserDTO(); dto.id = user.getId(); dto.firstName = user.getFirstName(); dto.lastName = user.getLastName(); return dto; } The DAO is as follows: public class DAO extends HibernateDaoSupport { private String adminUsername; private String adminPassword; private String godUsername; private String godPassword; public String getAdminUsername() { return adminUsername; } public void setAdminUsername(String adminUsername) { this.adminUsername = adminUsername; } public String getAdminPassword() { return adminPassword; } public void setAdminPassword(String adminPassword) { this.adminPassword = adminPassword; } public String getGodUsername() { return godUsername; } public void setGodUsername(String godUsername) { this.godUsername = godUsername; } public String getGodPassword() { return godPassword; } public void setGodPassword(String godPassword) { this.godPassword = godPassword; } public void saveOrUpdate(ModelObject obj) { getHibernateTemplate().saveOrUpdate(obj); } And my applicationContext.xml is as follows: <context:annotation-config/> <context:component-scan base-package="za.co.xxx.traintrack.server"/> <!-- Application properties --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>file:${user.dir}/@propertiesFile@</value> </list> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${connection.dialect}</prop> <prop key="hibernate.connection.username">${connection.username}</prop> <prop key="hibernate.connection.password">${connection.password}</prop> <prop key="hibernate.connection.url">${connection.url}</prop> <prop key="hibernate.connection.driver_class">${connection.driver.class}</prop> <prop key="hibernate.show_sql">${show.sql}</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.c3p0.min_size">5</prop> <prop key="hibernate.c3p0.max_size">20</prop> <prop key="hibernate.c3p0.timeout">300</prop> <prop key="hibernate.c3p0.max_statements">50</prop> <prop key="hibernate.c3p0.idle_test_period">60</prop> </props> </property> <property name="annotatedClasses"> <list> <value>za.co.xxx.traintrack.server.model.Answer</value> <value>za.co.xxx.traintrack.server.model.Company</value> <value>za.co.xxx.traintrack.server.model.CompanyRegion</value> <value>za.co.xxx.traintrack.server.model.Merchant</value> <value>za.co.xxx.traintrack.server.model.Module</value> <value>za.co.xxx.traintrack.server.model.Question</value> <value>za.co.xxx.traintrack.server.model.User</value> <value>za.co.xxx.traintrack.server.model.CompletedModule</value> </list> </property> </bean> <bean id="dao" class="za.co.xxx.traintrack.server.DAO"> <property name="sessionFactory" ref="sessionFactory"/> <property name="adminUsername" value="${admin.user.name}"/> <property name="adminPassword" value="${admin.user.password}"/> <property name="godUsername" value="${god.user.name}"/> <property name="godPassword" value="${god.user.password}"/> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory"> <ref local="sessionFactory"/> </property> </bean> <!-- enable the configuration of transactional behavior based on annotations --> <tx:annotation-driven transaction-manager="transactionManager"/> If I change the sessionFactory property to be autoCommit=true then my object does get persisited. <prop key="hibernate.connection.autocommit">true</prop>

• JBoss 7.1.1 + Spring 3.1 + JPA 2 (Hibernate 3.6.8) > Cannot parse beans.xml

  - by Mashrur

  Trying to deploy a JSF 2 app with Spring 3.1 + JPA 2 (Hibernte 3.6.8) into JBoss 7.1.1 AS. The app was working fine on tomcat 7. Now, I have already added and changed some configurations. Added jboss-deployment-structure.xml <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1"> <deployment> <exclusions> <module name="org.apache.log4j" /> <module name="javax.faces.api" slot="main"/> <module name="com.sun.jsf-impl" slot="main"/> <module name="org.hibernate"/> <module name="org.javassist" /> <module name="javaee.api" /> <module name="org.hibernate.validator" /> <module name="org.jboss.as.web" /> <module name="org.jboss.logging" /> <module name="javax.persistence.api" /> <module name="org.jboss.interceptor" /> </exclusions> </deployment> </jboss-deployment-structure> 2. Inside web.xml added these lines: <persistence-unit-ref> <persistence-unit-ref-name>persistence/persistenceUnit</persistence-unit-ref-name> <persistence-unit-name>persistenceUnit</persistence-unit-name> </persistence-unit-ref> 3. Inside applicationContext.xml, changed bean definition for entityManagerFactory by adding this property <property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"/> Now, do I still need to do something more than these which is obvious to you? Because, while I am trying to deploy it from eclipse indigo SR2, getting this 14:10:32,046 INFO [org.jboss.modules] JBoss Modules version 1.1.1.GA 14:10:33,054 INFO [org.jboss.msc] JBoss MSC version 1.0.2.GA 14:10:33,200 INFO [org.jboss.as] JBAS015899: JBoss AS 7.1.1.Final "Brontes" starting 14:10:36,375 INFO [org.xnio] XNIO Version 3.0.3.GA 14:10:36,384 INFO [org.jboss.as.server] JBAS015888: Creating http management service using socket-binding (management-http) 14:10:36,432 INFO [org.xnio.nio] XNIO NIO Implementation Version 3.0.3.GA 14:10:36,462 INFO [org.jboss.remoting] JBoss Remoting version 3.2.3.GA 14:10:36,587 INFO [org.jboss.as.logging] JBAS011502: Removing bootstrap log handlers 14:10:36,714 INFO [org.jboss.as.security] (ServerService Thread Pool -- 44) JBAS013101: Activating Security Subsystem 14:10:36,735 INFO [org.jboss.as.naming] (MSC service thread 1-2) JBAS011802: Starting Naming Service 14:10:37,043 INFO [org.jboss.as.mail.extension] (MSC service thread 1-6) JBAS015400: Bound mail session [java:jboss/mail/Default] 14:10:37,208 INFO [org.jboss.as.connector] (MSC service thread 1-7) JBAS010408: Starting JCA Subsystem (JBoss IronJacamar 1.0.9.Final) 14:10:37,295 INFO [org.jboss.as.security] (MSC service thread 1-7) JBAS013100: Current PicketBox version=4.0.7.Final 14:10:37,740 INFO [org.jboss.as.connector.subsystems.datasources] (ServerService Thread Pool -- 27) JBAS010403: Deploying JDBC-compliant driver class org.h2.Driver (version 1.3) 14:10:38,792 INFO [org.jboss.ws.common.management.AbstractServerConfig] (MSC service thread 1-3) JBoss Web Services - Stack CXF Server 4.0.2.GA 14:10:38,833 INFO [org.apache.coyote.http11.Http11Protocol] (MSC service thread 1-2) Starting Coyote HTTP/1.1 on http-localhost-127.0.0.1-8080 14:10:39,534 INFO [org.jboss.as.server.deployment.scanner] (MSC service thread 1-1) JBAS015012: Started FileSystemDeploymentService for directory F:\work\softwares\Application Servers\JBoss\jboss-as-7.1.1.Final\jboss-as-7.1.1.Final\standalone\deployments 14:10:39,618 INFO [org.jboss.as.remoting] (MSC service thread 1-3) JBAS017100: Listening on localhost/127.0.0.1:4447 14:10:39,623 INFO [org.jboss.as.remoting] (MSC service thread 1-2) JBAS017100: Listening on /127.0.0.1:9999 14:10:39,698 INFO [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) JBAS015014: Re-attempting failed deployment treasury.war 14:10:39,706 INFO [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) JBAS015003: Found com.misl.treasury.ui.war in deployment directory.

• Is it possible from Spring to inject the result of calling a method on a ref bean?

  - by Alex Worden

  Hi, Is it possible from Spring to inject the result of calling a method on a ref bean? I'm trying to refactor some cut/pasted code from two separate projects into a common class. In one of the projects, the code lives in a class I'll call "MyClient" that is being instantiated from Spring. It is injected with another spring-instantiated class "MyRegistry", then the MyClient class uses that class to look up an endpoint. All I really need is the endpoint String in my refactored class, which can be initialized via a Setter. I really cannot have a dependency on MyRegistry from MyClient in the refactored code. So, my question is this... is there a way I can inject the endpoint String from spring that was looked up in the MyRegistry class. So, I currently have: <bean id="registryService" class="foo.MyRegistry"> ...properties set etc... </bean> <bean id="MyClient" class="foo.MyClient"> <property name="registry" ref="registryService"/> </bean> But I'd like to have (and I know this is imaginary Spring syntax) <bean id="MyClient" class="foo.MyClient"> <property name="endPoint" value="registryService.getEndPoint('bar')"/> </bean> where MyRegistry will have a method getEndPoint(Stirng endPointName) Hope that makes sense from a the standpoint of what I'm trying to achieve. Please let me know if something like this is possible in Spring!

• How to make Spring load a JDBC Driver BEFORE initializing Hibernate's SessionFactory?

  - by Bill_BsB

  I'm developing a Spring(2.5.6)+Hibernate(3.2.6) web application to connect to a custom database. For that I have custom JDBC Driver and Hibernate Dialect. I know for sure that these custom classes work (hard coded stuff on my unit tests). The problem, I guess, is with the order on which things get loaded by Spring. Basically: Custom Database initializes Spring load beans from web.xml Spring loads ServletBeans(applicationContext.xml) Hibernate kicks in: shows version and all the properties correctly loaded. Hibernate's HbmBinder runs (maps all my classes) LocalSessionFactoryBean - Building new Hibernate SessionFactory DriverManagerConnectionProvider - using driver: MyCustomJDBCDriver at CustomDBURL I get a SQLException: No suitable driver found for CustomDBURL Hibernate loads the Custom Dialect My CustomJDBCDriver finally gets registered with DriverManager (log messages) SettingsFactory runs SchemaExport runs (hbm2ddl) I get a SQLException: No suitable driver found for CustomDBURL (again?!) Application get successfully deployed but there are no tables on my custom Database. Things that I tried so far: Different techniques for passing hibernate properties: embedded in the 'sessionFactory' bean, loaded from a hibernate.properties file. Nothing worked but I didn't try with hibernate.cfg.xml file neither with a dataSource bean yet. MyCustomJDBCDriver has a static initializer block that registers it self with the DriverManager. Tried different combinations of lazy initializing (lazy-init="true") of the Spring beans but nothing worked. My custom JDBC driver should be the first thing to be loaded - not sure if by Spring but...! Can anyone give me a solution for this or maybe a hint for what else I could try? I can provide more details (huge stack traces for instance) if that helps. Thanks in advance.

  greetings all,iam using spring security 3 and i want to perform some logic(saving some data in the session) when the user is visiting the site and he's remembered so i extended the GenericFilterBean class and performed the logic in the doFilter method then complete the filter chain by calling the chain.doFilter method,and then inserted that filter after the remember me filter in the security.xml file? but there's a problem is the filter is executed on each page even if the user is remembered or not is there's something wrong with the filter implementation or the position of the filter? and i have a simple question,is the filter chain by default is executed on each page? and when making a custom filter should i add it to the web.xml too? the filter class: package projects.internal; import java.io.IOException; import javax.servlet.FilterChain; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.security.core.Authentication; import org.springframework.security.core.context.SecurityContextHolder; import org.springframework.web.filter.GenericFilterBean; import projects.ProjectManager; public class rememberMeFilter extends GenericFilterBean { private ProjectManager projectManager; @Autowired public rememberMeFilter(ProjectManager projectManager) { this.projectManager = projectManager; } @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { System.out.println("In The Filter"); Authentication auth = (Authentication) SecurityContextHolder .getContext().getAuthentication(); HttpServletResponse response = ((HttpServletResponse) res); HttpServletRequest request = ((HttpServletRequest) req); // if the user is not remembered,do nothing if (auth == null) { chain.doFilter(request, response); } else { // the user is remembered save some data in the session System.out.println("User Is Remembered"); chain.doFilter(request, response); } } } the security.xml file: <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <global-method-security pre-post-annotations="enabled"> </global-method-security> <http use-expressions="true" > <remember-me data-source-ref="dataSource"/> <intercept-url pattern="/" access="permitAll" /> <intercept-url pattern="/images/**" filters="none" /> <intercept-url pattern="/scripts/**" filters="none" /> <intercept-url pattern="/styles/**" filters="none" /> <intercept-url pattern="/p/login" filters="none" /> <intercept-url pattern="/p/register" filters="none" /> <intercept-url pattern="/p/forgot_password" filters="none" /> <intercept-url pattern="/p/**" access="isAuthenticated()" /> <custom-filter after="REMEMBER_ME_FILTER" ref="rememberMeFilter" /> <form-login login-processing-url="/j_spring_security_check" login-page="/p/login" authentication-failure-url="/p/login?login_error=1" default-target-url="/p/dashboard" authentication-success-handler-ref="myAuthenticationHandler" always-use-default-target="false" /> <logout/> </http> <beans:bean id="myAuthenticationHandler" class="projects.internal.myAuthenticationHandler" /> <beans:bean id="rememberMeFilter" class="projects.internal.rememberMeFilter" > </beans:bean> <authentication-manager alias="authenticationManager"> <authentication-provider> <password-encoder hash="md5" /> <jdbc-user-service data-source-ref="dataSource" /> </authentication-provider> </authentication-manager> </beans:beans> any help?

• JavaOne: Parleys.com, Spring Vs. Java EE and HTML5 tooling

  - by delabassee

  Parleys.com, a 2012 Duke's Choice Award winner, is an E-Learning platform that host content from different sources (conferences, JUGs meetings, etc.). There is a lot of technical content available for online but also offline consumption, including many sessions on Java EE. Parleys has just released, for free, all the Devoxx 2011 sessions (video and slides sync'ed!). From a technical point of view, Parleys.com is interesting as they have switched from Spring to Java EE 6 to avoid being locked in a proprietary framework. During the GlassFish Community BoF, Stephan Janssen (Parleys.com and Devoxx founder) also presented how GlassFish is used to support 2000 concurrent Parleys users over a cluster of 2 GlassFish instances. Talking about Java EE and/or Spring, Harshad Oak has posted an update on the 'Spring Vs. Java EE' panel discussion that took place on Tuesday. As Arun said standards such as Java EE does not necessarily refrain innovation: "JBoss Forge & Arquillian from RedHat are great examples of innovation in the JavaEE community. Standardization is important but innovation does continue even within that framework." Simplicity, productivity along with HTML5 are the driving themes of Java EE 7. In terms of simplicity and productivity, the developer experience can also be improved by the tooling. Every NetBeans release comes with a large set of improvements, the just released NetBeans 7.3 beta is no exception. The goal of ‘NB 7.3’s Project Easel’ is to improve HTML5 development, something that will be handy for Java EE 7 developers. Project Easel can, for example, communicate directly to Chrome's WebKit engine, this feature was shown during Sunday's Technical Keynote at the end of the Java EE section. In this beta release, Chrome and the embedded JavaFX browser are the only supported browsers but the NetBeans team plan to add support, over time, for other WebKit based browsers. NetBans 7.3 beta NetBeans 7.3 screenscasts Today (i.e. Wednesday 3rd) is also the final exhibition day, so make sure to visit the Java EE and the GlassFish pods on the Java DEMOgrounds (Hilton Grand Ballroom, 9:30 am - 5:00 pm).

• Mock versus Implementation. How to share both approaches in a single Test class ?

  - by Arthur Ronald F D Garcia

  Hi, See the following Mock Test by using Spring/Spring-MVC public class OrderTest { // SimpleFormController private OrderController controller; private OrderService service; private MockHttpServletRequest request; @BeforeMethod public void setUp() { request = new MockHttpServletRequest(); request.setMethod("POST"); Integer orderNumber = 421; Order order = new Order(orderNumber); // Set up a Mock service service = createMock(OrderService.class); service.save(order); replay(service); controller = new OrderController(); controller.setService(service); controller.setValidator(new OrderValidator()); request.addParameter("orderNumber", String.valueOf(orderNumber)); } @Test public void successSave() { controller.handleRequest(request, new MockHttpServletResponse()); // Our OrderService has been called by our controller verify(service); } @Test public void failureSave() { // Ops... our orderNumber is required request.removeAllParameters(); ModelAndView mav = controller.handleRequest(request, new MockHttpServletResponse()); BindingResult bindException = (BindingResult) mav.getModel().get(BindingResult.MODEL_KEY_PREFIX + "command"); assertEquals("Our Validator has thrown one FieldError", bindException.getAllErrors(), 1); } } As you can see, i do as proposed by Triple A pattern Arrange (setUp method) Act (controller.handleRequest) Assert (verify and assertEquals) But i would like to test both Mock and Implementation class (OrderService) by using this single Test class. So in order to retrieve my Implementation, i re-write my class as follows @ContextConfiguration(locations="/app.xml") public class OrderTest extends AbstractTestNGSpringContextTests { } So how should i write my single test to Arrange both Mock and Implementation OrderService without change my Test method (sucessSave and failureSave) I am using TestNG, but you can show in JUnit if you want regards,

• @Autowire strange problem

  - by Javi

  Hello, I have a strange behaviour when autowiring I have a similar code like this one, and it works @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2{ ... } The problem is that I need that the Class2 implements an interface so I've only changed the Class2 so it's now like: @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2 implements IServiceReference<Class3, Long>{ ... } public interface IServiceReference<T, PK extends Serializable> { public T reference(PK id); } with this code I get a org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type for Class2. It seems that @ Transitional annotation is not compatible with the interface because if I remove the @Transitional annotation or the "implements IServiceReference" the problem disapears and the bean is injected (though I need to have both in this class). It also happens if I put the annotation @Transitional in the methods instead of in the Class. I use Spring 3.0.2 if this helps. Is not compatible the interface with the transactional method? May it be a Spring bug? Thanks

• Can not find Driver when using generic database bundle

  - by Marc

  I have a project that is build up from several OSGi bundles. One of them is a generic Database bundle that defines a DataSource that can be used throughout the project. The spring bean definition of this service is: <osgi:service interface="javax.sql.DataSource"> <bean class="org.postgresql.ds.PGPoolingDataSource"> <property name="databaseName" value="xxx" /> <property name="serverName" value="xxx" /> <property name="user" value="xxx" /> <property name="password" value="xxx" /> </bean> </osgi:service> Now, when using this DataSource is a different bundle, we get an error: No suitable driver found for jdbc:postgresql://localhost/xxx I have tried the following to add the org.postgresql.Driver to the DriverManager: Instantiated an empty bean for that Driver in the spring context, like this: <bean class="org.postgresql.Driver" /> Instantiated the Driver statically in one of the classes, like this: Class.forName("org.postgresql.Driver"); Added a file META-INF\services\java.sql.Driver with the content org.postgresql.Driver None of these solutions seems to help.

• How do I authenticate regarding EJB3 Container ?

  - by FMR

  I have my business classes protected by EJB3 security annotations, now I would like to call these methods from a Spring controller, how do I do it? edit I will add some information about my setup, I'm using Tomcat for the webcontainer and OpenEJB for embedding EJB into tomcat. I did not settle on any version of spring so it's more or less open to suggestions. edit current setup works this way : I have a login form + controller that puts a User pojo inside SessionContext. Each time someone access a secured part of the site, the application checks for the User pojo, if it's there check roles and then show the page, if it's not show a appropriate message or redirect to login page. Now the bussiness calls are made thanks to a call method inside User which bypass a probable security context which is a remix of this code found in openejb security examples : Caller managerBean = (Caller) context.lookup("ManagerBeanLocal"); managerBean.call(new Callable() { public Object call() throws Exception { Movies movies = (Movies) context.lookup("MoviesLocal"); movies.addMovie(new Movie("Quentin Tarantino", "Reservoir Dogs", 1992)); movies.addMovie(new Movie("Joel Coen", "Fargo", 1996)); movies.addMovie(new Movie("Joel Coen", "The Big Lebowski", 1998)); List<Movie> list = movies.getMovies(); assertEquals("List.size()", 3, list.size()); for (Movie movie : list) { movies.deleteMovie(movie); } assertEquals("Movies.getMovies()", 0, movies.getMovies().size()); return null; } });

• Spring AOP AfterThrowing vs. Around Advice

  - by whiskerz

  Hey there, when trying to implement an Aspect, that is responsible for catching and logging a certain type of error, I initially thought this would be possible using the AfterThrowing advice. However it seems that his advice doesn't catch the exception, but just provides an additional entry point to do something with the exception. The only advice which would also catch the exception in question would then be an AroundAdvice - either that or I did something wrong. Can anyone assert that indeed if I want to catch the exception I have to use an AroundAdvice? The configuration I used follows: @Pointcut("execution(* test.simple.OtherService.print*(..))") public void printOperation() {} @AfterThrowing(pointcut="printOperation()", throwing="exception") public void logException(Throwable exception) { System.out.println(exception.getMessage()); } @Around("printOperation()") public void swallowException(ProceedingJoinPoint pjp) throws Throwable { try { pjp.proceed(); } catch (Throwable exception) { System.out.println(exception.getMessage()); } } Note that in this example I caught all Exceptions, because it just is an example. I know its bad practice to just swallow all exceptions, but for my current use case I want one special type of exception to be just logged while avoiding duplicate logging logic.

How can I instruct my applicationContext.xml to load the properties with the given propertyPath system property without some ugly MethodInvokingBean which calls System.getProperty(''); My applicationContext.xml <bean id="systemPropertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/> <property name="placeholderPrefix" value="sys{"/> <property name="properties"> <props> <prop key="propertyPath">/default/path/to/server.properties</prop> </props> </property> </bean> <bean id="propertyResource" class="org.springframework.core.io.FileSystemResource" dependency-check="all" depends-on="systemPropertyConfigurer"> <constructor-arg value="sys{propertyPath}"/> </bean> <bean id="serviceProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="location" ref="propertyResource"/> </bean> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" ref="propertyResource"/> <property name="placeholderPrefix" value="prop{"/> <property name="ignoreUnresolvablePlaceholders" value="true"/> <property name="ignoreResourceNotFound" value="false"/> </bean> <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="prop{datasource.name}"/> </bean> with this configuration the propertyResource alsways complains about java.io.FileNotFoundException: sys{propertyPath} (The system cannot find the file specified) Any suggestions? ;-) Thanks gabe

• Spring 3 Controller Exception handler implementation problems

  - by predhme

  I was hoping to implement a single "ExceptionController" to handle exceptions that are thrown in execution of my other controllers' methods. I hadn't specified any HandlerExceptionResolver in my application context so according to the API documentation the AnnotationMethodHandlerExceptionResolver should be started. Verified as such in the source. So I am curious to know why the following isn't working. @Controller public class ExceptionController { @ExceptionHandler(NullPointerException.class) public ModelAndView handleNullPointerException(NullPointerException ex) { // Do some stuff log.error(logging stuff) return myModelAndView; } } @Controller public class AnotherController { @RequestMapping(value="/nullpointerpath") public String throwNullPointer() { throw new NullPointerException(); } } I see in the debug logs that the three default exception handlers are asked for handling of the exception, but nothing is done and I see "DispatcherServlet - Could not complete request". Followed by the user being displayed the stacktrace and a 500 Internal error.

• spring-mvc binding arraylist in form

  - by Mike

  In my controller I added an ArrayList to my model with the attribute name "users". Now I looked around and this is the method I found (including a question here): <form:form action="../user/edit" method="post" modelAttribute="users"> <table> <c:forEach var="user" items="${users}" varStatus="counter"> <tr> <td> <form:input path="users[${counter.index}].age"/> </td> <td><button type="submit" name="updateId" id="Update" value="${user.id}">Update</button></td> </tr> </c:forEach> </table> </form:form> But when I load the JSP page I get: .springframework.beans.NotReadablePropertyException: Invalid property 'projects[0]' of bean class [java.util.ArrayList]: Bean property 'users[0]' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? So apparantely this isn't the way to go, but in that case how do I bind an arraylist so I can edit the values?
