[Googoos🕊] 03. Spring | login Session & Join

01. Controller

 

MemberLoginController

package com.mygg.mygg.controller;

import com.mygg.mygg.dto.LoginDTO;
import com.mygg.mygg.service.MemberService;
import com.mygg.mygg.vo.MemberVO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;

import javax.annotation.Resource;
import javax.inject.Inject;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import java.util.Map;

@Controller
@RequestMapping("/member")
public class MemberLoginController {

    private final MemberService memberService;


    @Autowired
    public MemberLoginController(MemberService memberService) {
        this.memberService = memberService;
    }

    // login page
    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String loginGET(@ModelAttribute("loginDTO")LoginDTO loginDTO) {
        return "/member/login";
    }


    // login session
    @PostMapping("/user/login")
    public String loginPOST(LoginDTO dto, HttpServletRequest request) throws Exception {

        HttpSession session = request.getSession();
        System.out.println(dto.getEmail());
        Map<String,String> memberInform = memberService.login(dto);
        System.out.println(memberInform);
        if(memberInform.get("email").equals(dto.getEmail()) && memberInform.get("password").equals(dto.getPassword())){
        session.setAttribute("memberId",memberInform.get("id"));
            System.out.println("세션 생성");
            return "/member/loginSuccess";
        }else{
            System.out.println("비밀번호가 틀립니다.");
          return "redirect:./";
        }
    }

    // logout
    @RequestMapping(value = "/logout", method = RequestMethod.GET)
    public String logout(HttpSession session) throws Exception {
        session.invalidate();
        return "/member/logout";
    }

}

• Login Controller
• 로그인 상태를 유지하기 위해 Service 객체에서 LoginDTO에 있는 id 값으로 꺼내온 결과값을 세션에 저장해줘야한다.

 

MemberRegisterController

package com.mygg.mygg.controller;

import com.mygg.mygg.dto.MemberDTO;
import com.mygg.mygg.service.MemberService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/member")
public class MemberRegisterController {

    @Autowired
    private MemberService memberService;

    // Join page
    @GetMapping("/signup")
    public String registerGET() {
        return "/member/signup";
    }

    // Join 처리
    @PostMapping("/signup")
    public String registerPOST(MemberDTO memberDTO) {
        memberService.register(memberDTO);
        return "redirect:/member/login";
    }
}
