事务服务中的 ConstraintViolationException 没有回滚

我有一个名为 add() 的服务方法，它用 @Transactional 注释.

I've a service method called add() which is annotated with @Transactional.

我调用它，但是当在相应的 DAO 方法中发生 ConstraintViolationException 时，即使我指定不这样做，它也会回滚事务.

I call it but when a ConstraintViolationException occurs inside corresponding DAO method it'll rollback the transaction even when I specify not to.

我希望 ConstraintViolationException 被捕获，而不是 NotFoundException 被检查的异常会被抛出.

I expect that ConstraintViolationException to be caught and instead of it NotFoundException checked exception would be thrown.

@Override
@Transactional(noRollbackFor = ConstraintViolationException.class)
public User add(User user) throws NotFoundException {
    try {
        result = userDao.add(user);
    } catch (RuntimeException e) {
        throw new NotFoundException("Couldn't find group");
    }
}

有没有办法在没有事务回滚的情况下捕获ConstraintViolationException?

Is there a way to catch ConstraintViolationException without transaction rollback?

我使用的是 spring 3.1.1 和 hibernate 3.6.
