Spring MVC 3.x注解方式实例源码
首先说明一下使用的版本：JDK：1.6 Tomcat：6.0 Spring：3.2，使用到的Jar包截图：工程结构截图：接下来：web.xml文件配置：<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"

HelloController代码内容：package com.project.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/hello")
public class HelloController {
@RequestMapping("/index")
public ModelAndView index(HttpServletRequest request,HttpServletResponse response) throws Exception {
ModelAndView modelView = new ModelAndView();
modelView.addObject("msg","Hello Index");
modelView.setViewName("index");
System.err.println("执行index！");
return modelView;
}
@RequestMapping("/show")
public ModelAndView show(HttpServletRequest request,HttpServletResponse response) throws Exception {
ModelAndView modelView = new ModelAndView();
modelView.addObject("msg","Hello show");
modelView.setViewName("index");
System.err.println("执行show！");
return modelView;
}
}
OK，运行效果如图：
