@Transactional(rollbackFor = Exception.class) 和 @Transactional(propagation=Propagation.REQUIRED) 有什么区别 [英] What is difference between @Transactional(rollbackFor = Exception.class) and @Transactional(propagation=Propagation.REQUIRED)

问题描述

@Transactional(rollbackFor = Exception.class) 
public void foo1() {
    `/**Some Code**/`
}

@Transactional(propagation=Propagation.REQUIRED)
public void foo2() {
    `/**Some Code**/`
}

推荐答案

@Transactional(propagation=Propagation.REQUIRED) 和 @Transactional(rollbackFor = Exception.class)大致相同.由于 propagation=Propagation.REQUIRED 是 默认.因此，考虑到这一点，它们等效于 @Transactional(propagation=Propagation.REQUIRED) 和 @Transactional(propagation=Propagation.REQUIRED, rollbackFor = Exception.class).

@Transactional(propagation=Propagation.REQUIRED) and @Transactional(rollbackFor = Exception.class) are roughly the same. As propagation=Propagation.REQUIRED is the default. So with that in mind they are equivalent to @Transactional(propagation=Propagation.REQUIRED) and @Transactional(propagation=Propagation.REQUIRED, rollbackFor = Exception.class).

唯一的区别是如果没有 rollbackFor = Exception.class 它只会回滚 RuntimeExceptions 和 Error s 而不是其他异常发生.(使用 EJB 时 JEE 也是如此，并且行为也已转换为 Spring).

The only difference is that without the rollbackFor = Exception.class it will rollback only for RuntimeExceptions and Error s not for other exceptions that occur. (This is the same for JEE when using EJB and the behavior has been translated to Spring as well).

这也在@Transactional 的 javadoc.

This is also explained in the javadoc of @Transactional.
