이전 포스트(Spring Framework 다운로드) 참조 => http://blog.naver.com/sungback/90036900896

0. http://www.springsource.org/download 링크를 따라가서

spring-framework-2.5.6-with-dependencies.zip 을 다운받아 압축 해제한다.

1. 이클립스에서 File -> New -> Dynamic Web Project -> hellospring 이라고 하자.

2. WEB-INF -> lib 폴더에 아래 그림처럼 jar 파일을 복사한다.

1) 압축 해제 폴더\dist\spring.jar

2) 압축 해제 폴더\dist\modules\spring-webmvc.jar

3) 압축 해제 폴더\lib\jakarta-commons\commons-logging.jar

3. web.xml 을 아래와 같이 수정한다.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>hellospring</display-name>
<servlet>
  <servlet-name>spring2</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>spring2</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>

<welcome-file-list>
  <welcome-file>index.html</welcome-file>
  <welcome-file>index.htm</welcome-file>
  <welcome-file>index.jsp</welcome-file>
  <welcome-file>default.html</welcome-file>
  <welcome-file>default.htm</welcome-file>
  <welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>

4. Java Resource: src -> 우클릭 -> New -> Class

아래 소스 작성

package hellospring.web;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class HelloController implements Controller {
protected final Log logger = LogFactory.getLog(getClass());

@Override
public ModelAndView handleRequest(HttpServletRequest request,
   HttpServletResponse response) throws Exception {
        logger.info("hello 예제 정상 작동");//로그 메세지 보여준다.
        request.setAttribute("name", "홍길동");//name 홍길동 셋팅.
        return new ModelAndView("hello.jsp");//hello.jsp 로 가라.
}
}

5. WebContent -> 우클릭 -> JSP -> hello.jsp

<%@ 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>Hello Spring 예제</title>
</head>
<body>
<h3>Hello Spring 예제</h3>
Hello!!! <%=request.getAttribute("name") %>
</body>
</html>
