해볼것 

  • Member 테이블은 간단하게 소스코드로 작성 
  • 1. 엔티티, Dao , Controller 작성
  • 2. 직접 서버 연동해 결과창 확인해보기

시작 전 폴더, 클래스 , jsp 파일 생성 

Member.java

package site.metacoding.demo.domain;

import org.springframework.stereotype.Component;

import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class Member {
	private Integer id;
	private String name;
	private String password;
	private String email;
	
}

MemberDao.java

package site.metacoding.demo.domain;

import java.util.ArrayList;
import java.util.List;

import org.springframework.stereotype.Component;

@Component // Dao를 Ioc 컨테이너에 띄워줌, 다른 곳에서 굳이 한번더 객체 생성 해줄 필요없어짐.
public class MemberDao {

	public Integer Insert(String name, String password, String email) {
		System.out.println("Insert 성공");
		System.out.println(name);
		System.out.println(password);
		System.out.println(email);
		return 1;

	}

	public Integer Update(Integer id, String password) {
		System.out.println("Update 성공");
		System.out.println(password);
		return 1;
	}

	public Integer deleteById(Integer id) {
		System.out.println("Delete 성공");
		System.out.println(id);
		return 1;
	}
	
	// 회원 정보 보기는 아직DB 연결을 하지 않아서 임의로 데이터 생성 후 리
	public Member findById(Integer id) {
		Member m1 = new Member(1,"cos","1234","cos@naver.com");
		Member m2 = new Member(2,"ssar","12345","ssar@naver.com");
		
		if(id == 1) {
			return m1;
		}
		else if(id == 2) {
			return m2;
		}
		else {
			return null;
		}
		
	}
	
	// 모든 회원 정보는 리스트 타입
	public List<Member> findByAll() {
		Member m1 = new Member(1,"cos","1234","cos@naver.com");
		Member m2 = new Member(2,"ssar","12345","ssar@naver.com");
		
		List<Member> memberList = new ArrayList<>();
		memberList.add(m1);
		memberList.add(m2);
		
		return memberList;
		
	}

}

MemberController.java

package site.metacoding.demo.web;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;

import site.metacoding.demo.domain.Member;
import site.metacoding.demo.domain.MemberDao;

@Controller
public class MemberController {

	// MemberDao를 사용
	private MemberDao memberDao;
	public MemberController(MemberDao memberDao) {
		this.memberDao = memberDao;
	}

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

	@PostMapping("/member/join")
	public String join(String name, String password, String email) {
		Integer result = memberDao.Insert(name, password, email);
		if (result == 1) {
			return "member/loginForm";
		} else {
			return "error/serverError";
		}
	}

	@GetMapping("/member/{id}")
	public String detail(@PathVariable Integer id, Model model) {
		Member memberPS = memberDao.findById(1);
		model.addAttribute("member", memberPS);
		return "member/detail";

	}

}

<결과 화면>

Detail화면 Controller에서 임의로 id를 1로 주었다.

회원가입 화면 

Dao의 return값이 1일 경우

Dao에서 결과 return 값을 -1로 임의로 설정 했을 경우
