一步一步的我们试着使用Eclipse J2EE+Maven+Tomcat（Jetty） 搭建留住的web开发平台 Spring MVC的方法。
工具：Eclipse J2EE，Maven，，Tomcat
Eclipse J2EE+Maven+Tomcat（Jetty）：
Maven 3.3.3：
Tomcat 7.X：
1.安装基础环境：
没啥好说的，JDK，Eclipse，Maven，配置环境变量等。
2.打开Eclipse，做web开发，我们还需要安装一些插件。
Eclipse插件地址：Luna – （安装Web,XML,Java EE and OSGI Enterprise Development）
3.将Maven和Eclipse关联起来。略
4.新建Maven web项目。
5.修改pom.xml文件，将编译级别，需要的jar等信息写入pom.xml文件。然后Alt+F5刷新项目。

黄色蓝色或者砖红色，犹如童话世界。
