spring - 当受检异常在事务中传播时会发生什么？

Question

我知道事务管理器中的默认回滚策略是在发生 RuntimeExceptions 时自动回滚。但是，如果我有一个允许传播的已检查异常会发生什么？

Answer 1

However, please note that the Spring Framework's transaction infrastructure code will, by default, only mark a transaction for rollback in the case of runtime, unchecked exceptions; that is, when the thrown exception is an instance or subclass of RuntimeException. (Errors will also - by default - result in a rollback.) Checked exceptions that are thrown from a transactional method will not result in the transaction being rolled back.

即使抛出受检异常，Spring 也会提交事务，就好像一切正​​常一样。
如果需要，您可以配置对已检查异常的回滚。

<tx:advice id="txAdvice" transaction-manager="txManager">
  <tx:attributes>
     <tx:method name="get*" read-only="false" rollback-for="AnyCheckedException"/>
     <tx:method name="*"/>
  </tx:attributes>
</tx:advice>

将在 AnyCheckedException 时执行回滚被抛出。
