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

问题描述

不知是否有意义，而不是使用

I wonder whether it makes sense to use instead of

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

使用 Throwable

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

据我所知，捕捉错误将帮助我们正确行事，即使发生了非常糟糕的事情。或者它可能没有帮助？

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 ，因为如果发生错误，spring将默认回滚事务。

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标记事务对于运行时回滚，未经检查的异常;也就是说，抛出的异常是RuntimeException的实例或子类。 （错误也会 - 默认情况下会导致回滚）。从事务方法抛出的已检查异常不会导致在默认配置中回滚。

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.

或者查看 DefaultTransactionAttribute

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