SSH 入门例子

struts1.2.9+spring2.0.6+hibernate3.0.5 整合开发的一个例子

一个小例子，看看struts1.2.9+spring2.0.6+hibernate3.0.5 是如何整合在一起进行javaweb开发的


一个简单的OA小系统，下面是预览图和项目结构

 

 

这个SSH整合的例子，用到了许多经典的整合技巧，能帮助初学者清晰的理解整合的步骤和技巧，我们也可以使用这个框架为模版，来搭建自己SSH的环境。


首先我列出关键的整合步骤


1.建立WEB项目的目录结构

   a.strtus的 ActionServlet 配置在web.xml 中

   b.将spring的监听器 配置在web.xml

   c.字符乱码过滤器 配置在web.xml

2.编写spring的配置文件 applicationContext.xml

 

  a. 配置数据源

  b.让spring来管理SessionFactory

  c.配置事务

  d.配置Hibernate 属性以及映射文件

  e.定义DAO和DAO代理

  f.根据需要配置AOP

  g.定义struts的配置
