[프로젝트명]우클릭 - [Properties] - [Project Facets]

- Dynamic web Module 3.1로 변경

- java 1.8로 변경

Step2 : src/main/webapp/WEB-INF/spring/root-context.xml 설정

[ Namespace ] - aop, mybatis 체크

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</bean>
    
    <mybatis-spring:scan base-package="com.dbtest.dao"/>

</beans>

Step3

package : com.dbtest.dao

- Interface : Mapper.java

- class : Test.java

Mapper.java

package com.dbtest.dao;

import org.apache.ibatis.annotations.Param;

// 인터페이스를 통해 DB에 접근 
public interface Mapper {
	public String memberId(@Param("memberId") String memberId); 
}

Test.java

package com.dbtest.dao;

public class Test {
	private String memberId;
	private String memberPw;
	public String getMemberId() {
		return memberId;
	}
	public void setMemberId(String memberId) {
		this.memberId = memberId;
	}
	public String getMemberPw() {
		return memberPw;
	}
	public void setMemberPw(String memberPw) {
		this.memberPw = memberPw;
	}
	@Override
	public String toString() {
		return "Test [memberId=" + memberId + ", memberPw=" + memberPw + "]";
	}
}

Step4

- src/main/resource 아래 mapper 폴더 생성

- src/main/resource 아래 Mapper.xml 파일 생성

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.dbtest.dao.Mapper">
  <select id="memberId" resultType="String">
    select pw from test where id = #{memberId}
  </select>
</mapper>

데이터 베이스 구성

- 테이블명 : test , 컬럼 : id, pw

Step5 : com.dbtest.controller.Homcontroller.java 수정

Homcontroller.java

package com.dbtest.controller;

import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

import javax.servlet.http.HttpServletRequest;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.dbtest.dao.Mapper;

@Controller
public class HomeController {
	
	private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
	
	@Autowired
	public Mapper mapper;
	
	@RequestMapping(value = "/", method = RequestMethod.GET)
	public String home(Locale locale, Model model) {
		logger.info("Welcome home! The client locale is {}.", locale);
		
		Date date = new Date();
		DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
		
		String formattedDate = dateFormat.format(date);
		
		model.addAttribute("serverTime", formattedDate );
		
		return "index";
	}
	
	@RequestMapping(value = "/list", method = RequestMethod.POST)
	public String list(HttpServletRequest request, Model model) {
		
		String memberId = request.getParameter("memberId"); 
		model.addAttribute("memberId", mapper.memberId(memberId));
		return "list";
	}
	
}

Step6 : index.jsp , list.jsp 파일 생성

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<%String context = request.getContextPath(); %>
<form action="<%=context%>/list" method="post">
	<input type="text" name="memberId">
	<input type="submit" value="test">
</form>
</body>
</html>

list.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
${memberId}
</body>
</html>

[프로젝트명] 우클릭 - Run on Server

데이터베이스에 저장된 id 입력 - test버튼 클릭 - 입력한 id에 대응되는 비밀번호가 출력되면 성공

끝
