회원 웹 기능 - 홈 화면 추가

 

홈 컨트롤러 추가

package hello.hellospring.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class HomeController {

    @GetMapping("/")
    public String home() {
        return "home";
    }
}

 

회원 관리용 홈

  • 컨트롤러가 정적파일보다 우선 순위가 높다.
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<body>

<div class="container">
    <div>
        <h1>Hello Spring</h1>
        <p>회원 기능</p>
        <p>
            <a href="/members/new">회원 가입</a>
            <a href="/members">회원 목록</a>
        </p>
    </div>
</div> <!-- /container -->

</body>
</html>

 

회원 웹 기능 - 등록

 

회원 등록 폼 컨트롤러

package hello.hellospring.controller;

import hello.hellospring.domain.Member;
import hello.hellospring.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;

@Controller
public class   MemberController {

    private final MemberService memberService;

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

    @GetMapping("/members/new")
    public String createForm() {
        return "members/createMemberForm";
    }
}

 

회원 등록 폼  HTML

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<body>

<div class="container">

    <form action="/members/new" method="post">
        <div class="form-group">
            <label for="name">이름</label>
            <input type="text" id="name" name="name" placeholder="이름을 입력하세요">
        </div>
        <button type="submit">등록</button>
    </form>
</div> <!-- /container -->

</body>
</html>

 

웹 등록 화면에서 데이터를 전달 받을 폼 객체

package hello.hellospring.controller;

public class MemberForm {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

 

회원 컨트롤러에서 회원을 실제 등록하는 기능

package hello.hellospring.controller;

import hello.hellospring.domain.Member;
import hello.hellospring.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;

@Controller
public class   MemberController {

    private final MemberService memberService;

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

    @GetMapping("/members/new")
    public String createForm() {
        return "members/createMemberForm";
    }

    @PostMapping("/members/new")
    public String create(MemberForm form) {
        Member member = new Member();
        member.setName(form.getName());

        memberService.join(member);

        return "redirect:/";
    }
}

 

회원 웹 기능 - 조회

 

회원 컨트롤러에서 조회 기능

package hello.hellospring.controller;

import hello.hellospring.domain.Member;
import hello.hellospring.service.MemberService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;

import java.util.List;

@Controller
public class   MemberController {

    private final MemberService memberService;

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

    @GetMapping("/members/new")
    public String createForm() {
        return "members/createMemberForm";
    }

    @PostMapping("/members/new")
    public String create(MemberForm form) {
        Member member = new Member();
        member.setName(form.getName());

        memberService.join(member);

        return "redirect:/";
    }

    @GetMapping(value = "/members")
    public String list(Model model) {
        List<Member> members = memberService.findMembers();
        model.addAttribute("members", members);
        return "members/memberList";
    }
}

 

회원 리스트 HTML

  • HTTP, HTML form 등 웹 MVC와 관련된 자세한 내용은 스프링 웹 MVC 강의에서 다룰 예정이다.
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<body>

<div class="container">
    <div>
        <table>
            <thead>
            <tr>
                <th>#</th>
                <th>이름</th>
            </tr>
            </thead>
            <tbody>
            <tr th:each="member : ${members}">
                <td th:text="${member.id}"></td>
                <td th:text="${member.name}"></td>
            </tr>
            </tbody>
        </table>
    </div>
</div> <!-- /container -->

</body>
</html>
