Transaction problem with JPA2-spring-Hibernate - spring

Question

Hi I got a problem with the above integration of the frameworks.
I'm using JPA2 in a maven configuration with the library versions:
Spring 3.0.5
Hibernate 3.5.4
Hibernate-jpa-2.0-api-1.0.0.Final
I'm using the persistence.xml:
<persistence-unit name="AccountingPU" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.westernacher.wps.bnotk.fibu.domain.BaseEntity</class>
<class>com.westernacher.wps.bnotk.fibu.domain.AccountSettings</class>
<!-- This is not any more necessary, it will be done in spring config.
<properties>
<property name="hibernate.ejb.cfgfile" value="/hibernate.cfg.xml"/>
</properties> -->
</persistence-unit>
and the applicationContext.xml:
<context:annotation-config />
<context:component-scan base-package="com.westernacher.wps.bnotk.fibu.dao" />
<context:component-scan base-package="com.westernacher.wps.bnotk.fibu.service" />
<tx:annotation-driven transaction-manager="txManager"
proxy-target-class="false"
mode="proxy" />
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:dataSource-ref="dataSource">
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
</props>
</property>
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource"
p:driverClassName="${dataSource.driverClassName}" p:url="${dataSource.url}"
p:username="${dataSource.username}" p:password="${dataSource.password}" />
<context:property-placeholder location="classpath:datasource.properties" />
<bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager"
p:entityManagerFactory-ref="entityManagerFactory" />
The class AccountSettingsDaoImpl is annotated with #Repository.
The methods for database access in this class are marked with #Transactional:
#Transactional(readOnly=false)
public void save(E entity) {
// entityManager.merge(entity);
// entityManager.flush();
entityManager.persist(entity);
}
The Test class is the following:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration("/applicationContext.xml")
public class AccountSettingsDaoImplTest {
#Resource
private AccountSettingsDaoImpl accountSettingsDaoImpl;
private final static Long id=1L;
#Test
public void testSave() throws Exception {
AccountSettings accountSettings = new AccountSettings();
accountSettings.setCategory("A");
accountSettings.setDescription("adlkjsadhad asdlkasdkjahsdlkashd ");
accountSettingsDaoImpl.save(accountSettings);
Long localId = accountSettings.getId();
System.out.println("id="+localId);
}
}
But running my JUnit-Tests, I will get the following exception:
29.07.2011 18:46:01 org.springframework.test.context.TestContextManager prepareTestInstance
SCHWERWIEGEND: Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener#127e942f] to prepare test instance [com.westernacher.wps.bnotk.fibu.dao.AccountSettingsDaoImplTest#6b9c18ae]

Can anyone help me?
Best Regards, Daniel

You can't inject proxies by concrete type (if they are made by interface) - you should use the interface instead:
#Inject
private AccountSettingsDao accountSettingsDao;
