    <property name="suffix" value=".jsp"/>
</bean>

<bean id="/hello" class="com.scy.controller.HelloController"/>

HelloController.java

package com.scy.controller;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HelloController implements Controller {

    @Override
    public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse resp) throws Exception {
        ModelAndView mv = new ModelAndView();
        mv.addObject("msg", "Hello! SpringMVC~");
        mv.setViewName("hello");  // 通过前后缀拼接 --> /WEB-INF/jsp/hello.jsp
        return mv;
    }
}

你好.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>

${msg}

</body>
</html>
