i have some problems with configuring Spring MVC. I made a maven multi module project with the following modules:
/api
/domain
/repositories
/webapp
I like to share the domain and the
repositories between the api and the webapp (both web projects). First i want to configure the webapp to use the
repositories module so i added the dependencies in the xml file like this:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>domain</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>repositories</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
And my controller in the webapp module looks like this:
package com.mywebapp.webapp;
import com.mywebapp.domain.Person;
import com.mywebapp.
repositories.services.PersonService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/")
@Configuration
@ComponentScan("com.mywebapp.
repositories")
public class PersonController {
@Autowired
PersonService personservice;
@RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
Person p = new Person();
p.age = 23;
p.firstName = "John";
p.lastName = "Doe";
personservice.createNewPerson(p);
model.addAttribute("message", "Hello world!");
return "index";
}
}
In my webapp module i try to load configuration files in my web.xml like this:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/META-INF/persistence-context.xml, classpath:/META-INF/service-context.xml</param-value>
</context-param>
These files cannot be found so i get the following error:
org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [META-INF/persistence-context.xml]; nested exception is java.io.FileNotFoundException: class path resource [META-INF/persistence-context.xml] cannot be opened because it does not exist
These files are in the
repositories module so my first question is how can i make Spring to find these files?
I also have trouble Autowiring the PersonService to my Controller class did i forget to configure something in my XML?
Here is the error message:
[INFO] [talledLocalContainer] SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
