spring boot controller设置 @Transactional 不回滚的解决办法

 @Transactional
 @ApiOperation(value = "添加一个用户信息")
 @RequestMapping(value = "/create", method = RequestMethod.POST)
 public RESTful create() {
     return userService.insert(null, null);
 }

 public RESTful insert(User user, Role role) {
     try {
         Date date = new Date();

         user = new User();
         user.setName("tq2");
         user.setAge(26);
         user.setCreate_at(date);

         userMapper.insertUser(user);

         role = new Role();
         //role.setName("role1");
         role.setCreate_at(date);

         roleMapper.insert(role);

         return new RESTful(CodeEnum.成功.getCode(), CodeEnum.成功.getMsg());
     } catch (Exception ex) {
         return new RESTful(CodeEnum.系统异常.getCode(), CodeEnum.系统异常.getMsg());
     }
 }

1、role表的 name 字段不可空，但并不执行回滚

         return new RESTful(CodeEnum.系统异常.getCode(), CodeEnum.系统异常.getMsg());
     }
 }

 @Transactional

     } catch (Exception ex) {
         throw new RuntimeException();
