java - 回滚事务功能是否仅在抛出异常时才起作用？

Question

我的类(class)声明上方有此声明。 spring只会在抛出DAOException时回滚吗？

@Transactional(rollbackFor = { ManagerException.class, DAOException.class }) 

如果是这种情况，我怎样才能回滚错误的提交而不引发异常。目前我的数据库包函数返回错误消息，我想回滚并仍然向用户显示错误消息，而不抛出异常并使应用程序崩溃。

The documentation说:

You can also indicate a required rollback programmatically. Although very simple, this process is quite invasive, and tightly couples your code to the Spring Framework's transaction infrastructure:

public void resolvePosition() {
    try {
        // some business logic...
    } catch (NoProductInStockException ex) {
        // trigger rollback programmatically
        TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
    }
}
