Multiple Transaction manager issue

[elicer]

I have some doubts regarding the multiple transaction manager issue, I have two spring config file defined two spring configuration manager.

One file

  <tx:advice id="txAdvice" transaction-manager="transactionManager1">
 <bean id="transactionManager1" class="org.springframework.jdbc.DataSourceTransactionManager">
    ...

  </bean>

Another file

  <tx:advice id="txAdvice" transaction-manager="transactionManager2">
 <bean id="transactionManager2" class="org.springframework.jdbc.DataSourceTransactionManager">
    ...

  </bean>

Both of them was loaded into spring context, Now I have a service class, I didn't use the qulifier to indicate the transaction manager to use, I am wondering which transaction manager spring will going to use. Randomly pick up one or what?

public class TransactionalService {

@Transactional
public void setSomething(String name) { ... }

@Transactional
public void doSomething() { ... }


}

First off, you have both <tx:advice> definitions with same id. It means that one overrides another. You should use <aop:advisor> in combination with <tx:advice> definition. @Transactional annotation works in combination with <tx:annotation-driven/>.
If you have multiple transaction managers, use @Transactional("resource1") where <bean id="txManager"...><qualifier value="resource1"/></bean> is defined.
If you want to know the exact way how Spring determines transaction manager for annotated method, read through TransactionAspectSupport#determineTransactionManag er method.
