（二）.SpringMVC 學習-SpringMVC Hello World!

    開發工具：Eclipse,maven

    數據庫：MySql;

    運行環境：TomCat；

    JDK：JDK 1.7；

    項目工程爲：Dynamic Web Project；

至於如何建立maven 項目可參考：http://www.cnblogs.com/candle806/p/3439469.html

建立maven 項目，下面將介紹，如何建立hello world!想快速開發springmvc，整合spring,可先安裝spring插件，可參考個人：Spring插件安裝，及快速開發Spring Web mavan 項目（http://my.oschina.net/hapier/blog/712611）

到此環境已經搭建成功，一個簡單的helloworld已經over！

啓動項目：因爲項目配置 了tomcat插件【詳見pom.xml】，啓動項目能夠配置命令【clean  tomcat7:run】直接啓動,啓動方式以下：
