事物的手动回滚

1、方法中要开启事物

注解：@Transactional

2、遇到错误进行手动回滚

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();

注意：回滚之后 再进行return 

3、实例

@Transactionalpublic ResultJson updateInvoiceType(Strng nam) {               userDao.save(nam);if(StringUtils.isBlank(nam)){TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();return buildResultJson(FAIL, "错误", "");}return buildResultJson(SUCCESS, "成功", "");}
