I am trying Spring 3(.0.2.RELEASE) and JPA2 and Hibernate 3.5.1-Final...
One thing upsets me is that spring seems only accept a transaction Manager
named "transactionManager"
If I don't name it "transactionManager" , Spring will throws NoSuchBeanDefinitionException: No bean
named 'transactionManager' is defined.
Here is my config :
<context:component-scan base-package="destiny.data.mining"/>
<context:annotation-config/>
<bean id="miningEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="mining"/>
</bean>
<bean id="miningTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" >
<property name="entityManagerFactory" ref="miningEntityManagerFactory"/>
</bean>
<tx:advice id="txAdviceMining" transaction-manager="miningTransactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="save*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="*" propagation="SUPPORTS" read-only="true"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="methods" expression="execution(* destiny.utils.AbstractDao+.*(..))"/>
<aop:advisor advice-ref="txAdviceMining" pointcut-ref="methods"/>
</aop:config>
<tx:annotation-driven transaction-manager="miningTransactionManager"/>
In this config , an
Entity Manager Factory is not necessarily
named "entityManagerFactory" , and "txAdvice" is not necessarily
named "txAdvice" , either.
But I don't know why on earth Spring requires a transaction manager
named "transactionManager" ?
Is there any way not to name a transaction manager "transactionManager" ?
(I'm running multiple spring config files , so I try my best to avoid name-conflicting)
test code :
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:mining.xml"})
public class MiningPersonDaoTest
{
@Inject
private EntityManagerFactory miningEntityManagerFactory;
@Inject
private MiningPersonDao miningPersonDao;
@Transactional
@Test
public void testUpdate()
{
MiningPerson p = miningPersonDao.get(42L);
p.setLocationName("OOXX");
miningPersonDao.update(p);
System.out.println(p);
}
}
