（二）.SpringMVC 学习-SpringMVC Hello World!

    开发工具：Eclipse,maven

    数据库：MySql;

    运行环境：TomCat；

    JDK：JDK 1.7；

    项目工程为：Dynamic Web Project；

至于如何创建maven 项目可参考：http://www.cnblogs.com/candle806/p/3439469.html

创建maven 项目，下面将介绍，如何创建hello world!想快速开发springmvc，整合spring,可先安装spring插件，可参考我的：Spring插件安装，及快速开发Spring Web mavan 项目（http://my.oschina.net/hapier/blog/712611）

到此环境已经搭建成功，一个简单的helloworld已经over！

启动项目：由于项目配置 了tomcat插件【详见pom.xml】，启动项目可以配置命令【clean  tomcat7:run】直接启动,启动方式如下：
