SpringBoot学习笔记35——实现List校验@Validated

在 Controller 类上 加上@Validated。在需要校验的参数上加上 @Valid 。 就可以校验list里的实体类的属性

还需要在统一异常处理类中添加异常处理

    /**
     * 参数校验异常类
     *
     * @param exception
     * @return
     * @author 刘朋
     *

     */
    @ResponseStatus(HttpStatus.OK)
    @ExceptionHandler(ConstraintViolationException.class)
    @ResponseBody
    public ResponseMessage handlerConstraintViolationException(ConstraintViolationException exception) {
        log.warn(exception.getMessage(), exception);
        Set> constraintViolations = exception.getConstraintViolations();
        StringBuilder strBuilder = new StringBuilder();
        for (ConstraintViolation constraintViolation : constraintViolations) {
            String message = constraintViolation.getMessage();

            strBuilder.append(message).append("\n");
        }
        return Result.error(ResponseMessageCodeEnum.VALID_ERROR.getCode(), strBuilder.toString());
    }
