在以下架構春天@Transactional - javax.persistence.TransactionRequiredException
控制器 - >服務 - > DAO我試圖使服務操作@Transactional
在我UserService.fooFunction()我叫
Entity e = dao.find(key)
e.setProperty(something)
dao.update(e)
在末dao.update(e)中有
em.flush() //EntityManager obtained by @PersistenceContext annotation (injected by spring IoC)
調用flush()會拋出的PersistenceException:
javax.persistence.TransactionRequiredException No externally managed transaction is currently active for this thread
at org.eclipse.persistence.internal.jpa.transaction.JTATransactionWrapper.throwCheckTransactionFailedException(JTATransactionWrapper.java:86)
我的想法所剩無幾我做了什麼錯了,任何幫助,將不勝感激:)
您可以在下面找到我的配置大塊:
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="persistenceUnitName" value="myPU" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter" id="eclipselinkVendorAdapter">
..
</bean>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>
AOP部分:
<aop:config>
<aop:pointcut id="userServiceOperation"
expression="execution(* org.mypackage.UserServiceImpl.*(..))"/>
<aop:advisor pointcut-ref="userServiceOperation" advice-ref="txUserServiceAdvice"/>
</aop:config>
<tx:advice id="txUserServiceAdvice">
<tx:attributes>
<tx:method name="get*" read-only="true" propagation="REQUIRES_NEW"/>
<tx:method name="update*" read-only="false" propagation="REQUIRES_NEW"/>
<tx:method name="*" propagation="REQUIRES_NEW"/>
</tx:attributes>
</tx:advice>
沒有事務註解都存在。當我部署春應用程序可以看到
[<date>] DEBUG support.DefaultListableBeanFactory: Returning cached instance of singleton bean 'org.springframework.transaction.config.internalTransactionAdvisor'
[<date>] DEBUG interceptor.NameMatchTransactionAttributeSource: Adding transactional method [get*] with attribute [PROPAGATION_REQUIRES_NEW,ISOLATION_DEFAULT,readOnly]
[<date>] DEBUG interceptor.NameMatchTransactionAttributeSource: Adding transactional method [update*] with attribute [PROPAGATION_REQUIRES_NEW,ISOLATION_DEFAULT]
[<date>] DEBUG interceptor.NameMatchTransactionAttributeSource: Adding transactional method [*] with attribute [PROPAGATION_MANDATORY,ISOLATION_DEFAULT]
是 - 我正在運行的Sun的GlassFish應用服務器上的這個程序。我認爲我的問題解決了:)謝謝你的回覆! – Jan 2011-03-07 14:56:27
