회원관리

홈화면=======================================================

home controller 

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";
    }
}

 

localhost:8080 을 들어가면 @GetMapping 호출이 됨-> home.html 실행

 

스프링 컨트롤러가  static보다 우선순위

 

회원 웹 홈

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

<div class="container">
    <div>
        <h1>Hello Spring</h1>
        <p>회원기능</p>
        <p>
            <a href="/members/new">회원가입</a>
            <a href="/members">회원 목록</a>
        </p>
    </div>
</div>

</body>
</html>

 

home.html로 감

 

회원가입이면  /members/new

회원목록이면 /members

 

회원 등록=====================================================

memberController

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 MemberService memberService;

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

    @GetMapping("/members/new")
    public String createForm(){

        return "members/createMemberForm";
    }

 

members/createMemberForm        회원가입 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>

</body>
</html>

 

memberForm

package hello.hellospring.controller;

public class MemberForm {
    private String name;

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

}

 

memberController

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

}

 

 

등록하면 /members/new    method= post 형식으로 넘어감

postMapping으로 전달(데이터를 form에 넣어서 전달)

memberForm에 string name이 setname을 통해 input name이 들어감

getname으로 꺼냄

 

 

회원 조회=====================================================

MemberController

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

키가 members 첫번째 객체 꺼내서 member담고 memberList.HTML의  id와 name을 출력

getname으로 출력을 함

 

 

 

 

memberList.html

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

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


</body>
</html>

 

${} 모델안의 있는 것을 꺼냄
