Spring 유효성 검사(interface)

맴버 정보 수정하는 과정에서 유효성 검사를 정리합니다.

2. Contoller

    @ResponseBody

    @PutMapping(value = "")

    public String memberUpdate(Model model, @RequestBody MemberVO memberVo,

            BindingResult bindingResult) throws JsonProcessingException {

        logger.info("-------------PUT member -----");

        

        // 2019.01.24 otrodevym : 유효성 검사

        MemberValid memberValid = new MemberValid();

        memberValid.validate(memberVo, bindingResult);

        

        

        ObjectMapper mapper = new ObjectMapper();

        if (bindingResult.hasErrors()) {

            List<FieldError> errors = bindingResult.getFieldErrors();

            HashMap<String, Object> map = new HashMap<>();

            map.put("errors", errors);

            map.put("check", "fail");

            return mapper.writeValueAsString(map);

        }

        memberService.memberUpdateInfo(memberVo);

        return mapper.writeValueAsString("success");

    }

MemberValid를 생성하고 validate를 호출하여 유효성 검사를 합니다.

유효성 검사에서 에러가 발생하면 bindingResult에 저장되고 에러를 View단으로 전달합니다.
