I am using JUnit 4 to test Dao Access with Spring (annotations) and JPA (hibernate). The datasource is configured through JNDI(Weblogic) with an ORacle(Backend). This persistence is configured with just the name and a RESOURCE_LOCAL transaction-type
The application context file contains notations for annotations, JPA config, transactions, and default package and configuration for annotation detection. I am using Junit4 like so:
ApplicationContext
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="workRequest"/>
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="${database.target}"/>
<property name="showSql" value="${database.showSql}" />
<property name="generateDdl" value="${database.generateDdl}" />
</bean>
</property>
</bean>
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>workRequest</value>
</property>
<property name="jndiEnvironment">
<props>
<prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
<prop key="java.naming.provider.url">t3://localhost:7001</prop>
</props>
</property>
</bean>
<bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>
<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
JUnit TestCase
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class AssignmentDaoTest {
private AssignmentDao assignmentDao;
@Test
public void readAll() {
assertNotNull("assignmentDao cannot be null", assignmentDao);
List assignments = assignmentDao.findAll();
assertNotNull("There are no assignments yet", assignments);
}
}
regardless of what changes I make I get:
No unique bean of type [javax.persistence.EntityManager] is defined
Any hint on what this could be. I am running the tests inside eclipse.
