비밀번호 찾기 form

• 해당 input에 적절하게 입력하지 않을 시 css로 error효과를 넣기위해 div 삽입

<form class = "content" action="pw_auth.me" method="post">

인증번호 발송 Controller

    public ModelAndView pw_auth(HttpSession session, HttpServletRequest request, HttpServletResponse response) throws IOException {

        }

 

인증번호 입력한 값이 동일하지 확인하는 Controller

@RequestMapping(value = "/pw_set.me", method = RequestMethod.POST)
public String pw_set(@RequestParam(value="email_injeung") String email_injeung,
            @RequestParam(value = "num") String num) throws IOException{
        
        if(email_injeung.equals(num)) {
            return "YM/pw_new";
        }
        else {
            return "YM/pw_find";
        }
} //이메일 인증번호 확인

 

새비밀번호 입력 후 DB업데이트 Controller

@RequestMapping(value = "/pw_new.me", method = RequestMethod.POST)
    public String pw_new(MemberVO vo, HttpSession session) throws IOException{
        int result = memberSV.pwUpdate_M(vo);
        if(result == 1) {
            return "jj/loginForm";
        }
        else {
            System.out.println("pw_update"+ result);
            return "YM/pw_new";
        }
}
