怎样确保java代码在抛出异常时都回滚，而不只是运行时异常

      /** TransactionAspectSupport手动回滚事务：*/

       @Transactional(rollbackFor = { Exception.class })  

       public boolean test() {  

            try {  

               doDbSomeThing();    

            } catch (Exception e) {  

                 e.printStackTrace();     

                 //使用TransactionAspectSupport确保出现异常以后，事务能回滚

                 TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();  

                 return false;

            }  

           return true;

      }
