Struts2.2+Spring3.1+Hibernate3.6整合(登录示例及CRUD操作)

一 运行环境: XP3+Myeclipse6.6+Tomcat7
二 项目框架版本号:Struts2 version: 2.2.1.1,Spring version: 3.1,Hibernate version:3.6,在Hibernate下有个jar为:javassist-3.12.0.GA.jar,在这个示例中用的是:javassist-3.7.ga.jar,这二个在这个示例中都可以用,没问题,一般原则用新版本的
项目所用jar文件如下图

三 具体实现如下:

1 配置文件:

Web.xml

Xml代码 
Struts2.xml文件如下:
