spring的事务中程序控制事务成功失败（Transaction marked as rollback）

A方法之外加有事务管理拦截器，在A方法中做一系列操作，操作过程中捕获了一个异常，因为此异常不影响业务，捕获后需要正常向下运行，最终事务管理器提交事务时报了如下错误
Transaction has been rolled back because it has been marked as rollback 
原因就是发生异常后当前的事务就被标记为rollback-only，外层事务管理器再commit时就会抛此异常，解决方法是
<bean id="transactionManager"
  class="org.springframework.orm.hibernate3.HibernateTransactionManager">
  <property name="sessionFactory">
   <ref bean="sessionFactory" />
  </property>
  <property name="globalRollbackOnParticipationFailure" value="false" />
 </bean>

在 org.springframework.transaction.support.AbstractPlatformTransactionManager 中有个叫

isGlobalRollbackOnParticipationFailure的参数，默认是true.

源码中说明：

Switch this to "false" to let the transaction originator make the rollback decision. If a participating transaction fails with an exception, the caller can still decide to continue with a different path within the transaction. However, note that this will only work as long as all participating resources are capable of continuing towards a transaction commit even after a data access failure: This is generally not the case for a Hibernate Session, for example; neither is it for a sequence of JDBC insert/update/delete operations.

 

大意是：如果isGlobalRollbackOnParticipationFailure为false,则会让主事务决定回滚，如果当遇到exception加入事务失败时，调用者能继续在事务内决定是回滚还是继续。然而，要注意是那样做仅仅适用于在数据访问失败的情况下且只要所有操作事务能提交。
