MyBatis Domain 클래스 생성

MyBatis Mapper 인터페이스 생성

package com.iot.db.mapper;

MyBatis Mapper XML파일 생성

<?xml version="1.0" encoding="UTF-8"?>

	public List<UserInfo> listUserInfoFormData() throws Exception {
		return userInfoMapper.listUserInfo();
	}

}

컨트롤러 클래스 수정

서비스로 사용자리스트를 조회해서 modelMap에 사용자리스트(userlist)를 설정

package com.iot.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.iot.db.domain.UserInfo;

@Controller
public class IotController {

	public String hello_world(ModelMap modelMap) throws Exception {
		List<UserInfo> userlist = service.listUserInfoFormData();
		modelMap.addAttribute("userlist", userlist);
		return "/hello_world";
	}

}

hello_world.jsp에 데이터 전달

컨트롤러에서 전달받은 사용자리스트(userlist)를 반복해서 사용자정보를 출력

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

출처 : Get to Spring ApplicationContext from everywhere (The clean way)

Spring 컨터이너안의 Bean 객체를 어디에서든 얻어오는 Tip

ApplicationContextProvider 클래스

ApplicationContextProvider 클래스를 만들고, 이 클래스는 ApplicationContextAware 인터페이스를 구현합니다.

package com.iot.util;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class ApplicationContextProvider implements ApplicationContextAware {
	
	private static ApplicationContext ctx = null;

	public static ApplicationContext getApplicationContext() {
		return ctx;
	}

	public void setApplicationContext(ApplicationContext ctx) throws BeansException {
		this.ctx = ctx;
	}

}

ApplicationContext 환경파일 추가

이 Bean을 ApplicationContext 구성 파일에 설정합니다.

	<bean id="applicationContextProvider" class="com.iot.util.ApplicationContextProvider"></bean>

BeanUtils 클래스

사용하기 쉽게 유틸클래스를 만듭니다.

package com.iot.util;

import org.springframework.context.ApplicationContext;

public class BeanUtils {
	
	public static Object getBean(String beanId) {
		
		ApplicationContext applicationContext = ApplicationContextProvider.getApplicationContext();

		if( applicationContext == null ) {
			throw new NullPointerException("Spring의 ApplicationContext초기화 안됨");
		}
		
		/*
		String[] names = applicationContext.getBeanDefinitionNames();
		for (int i=0; i<names.length; i++) {
			System.out.println(names[i]);
		}
		*/
		
		return applicationContext.getBean(beanId);
	}
}

	DepartmentsService service = (DepartmentsService) BeanUtils.getBean("departmentsService");

Domain 객체

출처 : 혹시 DTO(VO) 작성하시나요? - SLiPP

프레임워크마다 VO, Command, Domain, DTO, TO 여러가지 이름으로 부르지만, MyBatis에서는 Domain이라고 부르고, Domain객체는 데이터베이스에서 조회된 데이터를 객체에 담아서 jsp에 실어 사용자에게 전달합니다.

package com.iot.domain;

import java.sql.Timestamp;

public class TbluserDomain {

	// pk
	private int seq;

	private String user_id;
	private String pass;
	private String nick;
	private Timestamp joindate;
	private String email;
	private String sex;

	private String delete_flag = "N";

	public void setSeq(int seq) {
		this.seq = seq;
	}

	public int getSeq() {
		return this.seq;
	}

	public void setUser_id(String user_id) {
		this.user_id = user_id;
	}

	public String getUser_id() {
		return this.user_id;
	}

	public void setPass(String pass) {
		this.pass = pass;
	}

	public String getPass() {
		return this.pass;
	}

	public void setNick(String nick) {
		this.nick = nick;
	}

	public String getNick() {
		return this.nick;
	}

	public void setJoindate(Timestamp joindate) {
		this.joindate = joindate;
	}

	public Timestamp getJoindate() {
		return this.joindate;
	}

	public void setEmail(String email) {
