Springboot Validiation Method参数校

Springboot 版本 2.2.2.RELEASE
实体校验成功，但是方法校验失败

生效条件

1. 方法必须是public
2. 方法的类名上要有注解@Validated

两个条件达成即可生效校验注解

需要注意的是：校验失败会抛出异常ConstraintViolationException

示例代码：

@RestController
@Slf4j
@RequiresRoles(Constant.ROLE_KEY.ADMIN)
@RequestMapping("api/v1/sys/plan")
//标记类名
@Validated
public class PlanController  extends BaseController {


    @GetMapping("/{planKey}/enable")
    @Transactional
    public JsonResult<PlanEntity> setPlanEnable(
            @PathVariable String planKey,
            @EnumValid(value = Constant.STATUS.class,message = "枚举不正确") Integer enableStatus){
        return succeed(planService.setPlanEnable(planKey,enableStatus));
    }
}

声明：@EnumValid是自定义注解

捕获异常：

@ControllerAdvice
@ResponseBody
@Slf4j
public class MyExceptionHandler {


    @ExceptionHandler(ConstraintViolationException.class)
    public JsonResult<List<String>> ConstraintViolationException(ConstraintViolationException e){
        List<String> list= CollectionUtil.newArrayList();
        for (ConstraintViolation<?> v:e.getConstraintViolations()){
            list.add(v.getMessage());
        }
        return JsonResult.error(Constant.ERROR_CODE.VALIDATOR_EXCEPTION,list);
    }
}
