Question

我正在尝试将EJB事务传播到使用@Transactional注释的Pojo。

在EJB和Pojo中，事务都有效，但它们似乎没有相互通信。

我看不到Pojo的事务在EJB中活跃。

我的EJB就像：

@Stateless(name = "MyEJB", mappedName = "MyEJB")
@Remote(IMyEjb.class)
@Interceptors(SpringBeanAutowiringInterceptor.class)
public class MyEJBBean implements IMyEjb {

@Autowired
private MyService myService;

@Resource
TransactionSynchronizationRegistry tsr;

@Override
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public Customer doMyStuff(String username) throws BusinessException{
      Customer customer = myService.doMyStuff(username);
    System.out.println("Pojo transaction:" + TransactionSynchronizationManager.isActualTransactionActive());
    System.out.println("Ejb transaction:" + tsr.getTransactionStatus());  
    customer = myService.doMyStuff(username);

    return customer;       

}
}

Pojo实现如下：

@Component
public class MyService {

@Transactional(Transactional.TxType.REQUIRED)
public Customer doMyStuff(String username){
  System.out.println("Pojo transaction in object:" + TransactionSynchronizationManager.isActualTransactionActive());

   return new Customer();

}
}

我尝试过很多Spring配置实际上我正在使用以下内容：

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/OracleDS"
        expected-type="javax.sql.DataSource" />

 <bean id="transactionManager" 
      class="org.springframework.transaction.jta.JtaTransactionManager">
   <property name="transactionManagerName" value="java:appserver/TransactionManager"/>
   <property name="userTransactionName" value="java:comp/UserTransaction"/>
</bean>             

<bean id="entityManagerFactory" 
      class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
      p:dataSource-ref="dataSource"
      p:persistenceUnitName="oracle">
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
</bean>


<context:load-time-weaver/>
<tx:annotation-driven transaction-manager="transactionManager"  mode="aspectj" />    
 <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
 </beans>

如果我运行代码，我得到了以下输出： Pojo交易：错误 Ejb交易：0 对象中的Pojo事务：true。 Ejb交易：0表示它是活跃的。 http://docs.oracle.com/javaee/5/api/constant-values.html#javax.transaction.Status.STATUS_ACTIVE

现在我期待一个错误的结果，或者我该怎么办才能在ejb中打开pojo事务。

Answer 1

将 @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) 更改为 @org.springframework.transaction.annotation.Transactional(propagation = Propagation.REQUIRES_NEW) 或 @javax.transaction.Transactional(javax.transaction.Transactional.TxType.REQUIRES_NEW)

EJB Transaction不会启动pojo事务
