SpringMVC框架的多表查询和增删查改

必须声明本文章==》http://www.cnblogs.com/zhu520/p/7883268.html

一：

1）：我的运行环境

我使用myeclipse（你也可以使用eclipse），tomcat7

jar包 放在百度云，托到文章最后有链接下载即可（其实也可以根据我之前http://www.cnblogs.com/zhu520/p/7772823.html 去弄，不需要去网上下载（但是只是对myeclipse而言，eclipse还是要到网上下载的jar包的））

2）：包的情况

3）：配置的文件需要applicationContext.xml和springmvc.xml，不需要struts.xml配置

可以去看篇链接讲解了SpringMVC与Struts2区别 或者这篇 http://blog.csdn.net/gstormspire/article/details/8239182/
