微信开发准备第二步 springmvc mybatis项目结构搭建

前面一篇有说道如何在MyEclipse中搭建maven项目，这里将继续介绍如何在搭建好的基础maven项目中引入我们常用的javaweb框架——SpringMVC！

①在建立好的maven项目中的pom.xml文件引入依赖，代码如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

 <version>0.0.1-SNAPSHOT</version>
 <name>wechat</name>
 <url>http://maven.apache.org</url>

②修改项目路径下的web.xml文件如下：
