Spring

和struts整合时的坚挺程序

<listener>

     <listener-class>

      org.springframework.web.context.ContextLoaderListener

     </listener-class>

   </listener>

 

 

 

 

 

 

 

 

           三大框架整合注意

 

1. 先将struts导入，（注意记得添加strtus-spring-plugin插件包）

2. 导入hibernate，顺便添加hibernate-    annotation支持

不建立数据源

不创建sessionFactory

 

3添加spring记得导入前四个包和 web包

不创建sessionFacotory

3. 当所有的都加进入之后，记得删除asm-2.2.5  xerot包

4.

5. 最后一定要记得 将spring的监听配置到web.xml
