Spring Boot API 서버 테스트 4

1. 기존 API 테스트

get url 변경 : test -> members
method 명 변경 : testMembers -> getMembers
postman 사용
New http Request 생성
API 출력결과 확인

url : GET/ http://localhost:8080/members

2. 파라미터 사용 메소드 추가

id 파라미터를 통해 단일 멤버 호출 API 작성

MemberController.java

	@Autowired
	private MembersService service;
	
	@GetMapping(path="/members")
	public List<Member> getAllMembers() {
		return service.getAllMembers();
	}
	
	@GetMapping(path="/members/{id}")
	public Member getMember(@PathVariable Integer id) {
		return service.getMember(id);
	}

MemberService.java

package com.example.demo.service;

import java.util.List;

import com.example.demo.dto.Member;

public interface MembersService {
	List<Member> getAllMembers();
	Member getMember(Integer id);
}

MemberServiceImpl.java

package com.example.demo.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.example.demo.dao.MembersDAO;
import com.example.demo.dto.Member;
import com.example.demo.service.MembersService;

@Service
public class MembersServiceImpl implements MembersService{
	@Autowired
	private MembersDAO dao;
	
	@Override
	public List<Member> getAllMembers(){
		return dao.getAllMembers();
	}
	
	@Override
	public Member getMember(Integer id) {
		return dao.getMember(id);
	}
}

MembersDAO.java

package com.example.demo.dao;

import java.util.List;

import org.springframework.stereotype.Repository;

import com.example.demo.dto.Member;

@Repository
public interface MembersDAO {
	List<Member> getAllMembers();
	Member getMember(Integer id);
}

mapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.demo.dao.MembersDAO">
	<select id="getAllMembers" resultType="com.example.demo.dto.Member">
		SELECT * FROM members
	</select>
	<select id="getMember" parameterType="int" resultType="com.example.demo.dto.Member">
		SELECT * FROM members WHERE id= #{id}
	</select>
</mapper>

3. 추가 메소드 출력 확인

url : GET/ http://localhost:8080/members/1
