一、源码简介
该源码是一个java web项目工程,主要是测试Spring的web层MVC框架，主要包括src、WebRoot主目录，其中src为java源码目录，包括HelloController.java文件，WebRoot主要web工程的相关资源存放目录。项目截图如下所示，点击跳转查看GitHub源码（如需下载基于注释@RequestMapping的spring4以上版本完整MVC的项目源码,点击spring4-mvc项目）
二、项目快照（springmvc低版本）
1. mvc相关xml配置文件
<?xml version="1.0" encoding="UTF-8" ?>@b@<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">@b@@b@<beans>@b@@b@ <bean id="viewResolver"@b@ class="org.springframework.web.servlet.view.InternalResourceViewResolver">@b@ <property name="prefix" value="/WEB-INF/jsp/" />@b@ <property name="suffix" value=".jsp" />@b@ </bean>@b@@b@ <bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">@b@ <property name="mappings">@b@ <props>@b@ <prop key="/hello.do">helloController</prop>@b@ </props>@b@ </property>@b@ </bean>@b@@b@ <bean id="helloController" class="com.ideawu.HelloController">@b@ <!--@b@ <property name="helloManager" ref="helloManager" />@b@ -->@b@ </bean>@b@@b@</beans>
2. Controller层代码
package com.ideawu;@b@@b@import org.springframework.web.servlet.mvc.Controller;@b@import org.springframework.web.servlet.ModelAndView;@b@@b@import javax.servlet.http.HttpServletRequest;@b@import javax.servlet.http.HttpServletResponse;@b@@b@ @b@public class HelloController implements Controller {@b@ /*@b@ * private HelloManager helloManager;@b@ * @b@ * public void setHelloManager(HelloManager helloManager) {@b@ * this.helloManager = helloManager; }@b@ */@b@@b@ public ModelAndView handleRequest(HttpServletRequest request,@b@ HttpServletResponse response) throws Exception {@b@@b@ request.setAttribute("hello_1", "你好啊, Spring!");@b@ request.setAttribute("hello_2", "Hello World!");@b@@b@ return new ModelAndView("hello");@b@ }@b@@b@}3. 访问测试页，如http://127.0.0.1:9999/SpringMvc/hello.do，效果如下
下面基于spring4.1.4相关依赖包（spring-beans、spring-aop、spring-context、spring-expression、spring-mvc及spring-web等包），项目截图如下，项目本地下载，云盘下载
