Spring 事务:在 Exception 或 Throwable 上回滚 [英] Spring transaction: rollback on Exception or Throwable

问题描述

我想知道用

@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)

使用Throwable

@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Throwable.class)

据我所知，即使发生了非常糟糕的事情，捕捉 Error 也能帮助我们正确行事.或者也许它没有帮助?

As I understand catching Error will help us behave correctly even when something really bad happen. Or maybe it wouldn't help?

您不需要显式指定rollbackFor = Throwable.class，因为如果发生Error，spring 默认会回滚事务.

You don't need to explicitly specify rollbackFor = Throwable.class, because spring will by default rollback the transaction if an Error occurs.

参见 12.5.3 回滚声明性事务

在其默认配置中，Spring Framework的事务基础结构代码仅在运行时、未检查异常的情况下将事务标记为回滚；也就是说，当抛出的异常是 RuntimeException 的实例或子类时.(错误也会 - 默认情况下 - 导致回滚).从事务方法抛出的已检查异常不会导致默认配置中的回滚.

In its default configuration, the Spring Framework's transaction infrastructure code only marks 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 do not result in rollback in the default configuration.

或者看看DefaultTransactionAttribute

public boolean rollbackOn(Throwable ex) {
    return (ex instanceof RuntimeException || ex instanceof Error);
}
