Spring 시작 및 maven 설정 - controller에서 jsp로 값 넘기기까지

Spring 시작하기

Controller를 통해서 jsp 화면까지 호출

intelliJ -Project 생성

Maven 선택 후, SDK와  archetype 선택

GroupId와 ArtifactId를 정해주자.

Maven 셋팅하는 부분.

전 그냥 디폴트 그대로 사용했어요.

Project Name까지 지어주면 끝

기본적으로 생성되는 파일들

pom.xml 설정

spring 버전은 통일하기 때문에 properties로 관리해요.

maven에서 tomcat을 실행시키기 위해 plugins를 추가했어요.

Maven Reimport

pom.xml 파일에서 오른쪽 버튼을 클릭하면 나옵니다.

web.xml 설정

Run Configuration 설정

Run Configuration 창에서 + 버튼을 누르고 Maven을 선택

이름 지어주고, Command line에 입력하면 끝!

Working directory는 알아서 입력 되있음

실행!! console에 이렇게 뜨면 tomcat 실행 성공!

index.jsp

실행해보자!!

성공!!

main 밑에 java 폴더를 생성하고, Source Root로 설정

패키지명과 파일명은 원하는데로~

Controller

package springstudy.startstudy.web;

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

/**
 * Created by HeeChul on 2016. 2. 25..
 */

@Controller
@RequestMapping("/springstudy/startstudy")
public class StartStudyController {
   @RequestMapping("/helloWorld")
   public void helloWorld(Model model) {
      model.addAttribute("name", "Chori");
      model.addAttribute("hello", "Hello Spring Study!!!");
   }
}

resources 밑에 spring 폴더를 만들고, core-servlet.xml 생성

core-servlet.xml

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

        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <context:component-scan base-package="springstudy">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" />
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Repository" />
    </context:component-scan>

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

controller의 RequestMapping과 동일하게

webapp 밑에 jsp 폴더를  만들고, springstudy 폴더를 만든 후, startstudy 폴더 생성

메소드의 RequestMapping과 동일하게 helloWorld.jsp 생성!

helloWorld.jsp

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Chori Spring Study</title>
    </head>
    <body>
        <h2>Welcom!!</h2>
        <h2>
            ${name}, ${hello}
        </h2>
    </body>
</html>

controller에서 model의 attribute에 추가했던 name과 hello를 el태그를 사용하여 출력.

서버를 재기동 한뒤,

RequestMapping에 설정한 대로 주소창에 호출!!

성공!!!

설명은 나중에...
