What is difference between @Transactional(rollbackFor = Exception.class) and @Transactional(propagation=Propagation.REQUIRED)

问题

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

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

回答1:

@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).

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).

This is also explained in the javadoc of @Transactional.

Firstly, by default propagation is always present if you write it or not. If you write rollbackFor then the transaction will be rollback if an exception happens.
