spring事物不回滚

@Transactional(rollbackFor = { Exception.class })
 public void test() {
 try {
 doDbStuff1();
 doDbStuff2();
 } catch (Exception e) {
 e.printStackTrace();
 TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();//就是这一句了，加上之后，如果doDbStuff2()抛了异常,                                                                                       //doDbStuff1()是会回滚的
 }
 }
