　　web

lib引入Spring框架libs/*.jar

touch web.xmlspring

touch jsp/hello.jsp
　　文件名稱很重要！spring-mvc

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
"hello world"
</body>
</html>

touch www.xi.com.mvcController.javamvc

package www.xi.com;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class mvcController {

    private static final Log logger = LogFactory.getLog(mvcController.class);

    @RequestMapping("/hello")
    public String hello() {
        logger.info("hello called");

        return "hello";
    }

}

執行訪問：
http://localhost:8080/SpringMVC/helloapp

顯示：框架

「hello world」
