spring-mvc.xml

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

  <context:component-scan base-package="com.org.controller" />  <!-- 注解扫描 -->
  <bean

    <property name="prefix" value="/" />  <!-- 配置访问jsp文件访问路径 -->
    <property name="suffix" value=".jsp" />
  </bean>

</beans>

Controller层TestContorller.xml

package com.org.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class TestContorller {

  @RequestMapping(value = "hello")
  public ModelAndView helAndViewlo() {
    ModelAndView mav = new ModelAndView();
    mav.addObject("msg", "Hello,word!");
    mav.setViewName("index");
    return mav;
  }
}

创建jsp页面 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>
    ${msg}
</body>
</html>
