程序设计

1、系统总体方案。

本系统采用经典的j2ee的三层机构，即表现层、中间层（业务逻辑层）、持久层。

vis图插不进去，拉到把

2、程序详细设计。

2.1、数据库设计。

        2.1.1、基础数据

        用户权限、角色、用户组基础数据设计。

        2.1.2、业务数据

        业务对象：主帖、复帖、用户、分类模块。

        根据业务需求将T_USER表扩展如下：

             

       对象用户、好友、好友信息关系。

2.2、PO层设计。

              2.2.1、实体类。

              每个数据库表代表一个实体类，具体设计如下：

             

       Notice：BaseObject源码如下

      

       2.3、DAO设计。

             

       Notice：BaseHibernateDAO源码

             

       2.4、SERVICE层设计。

             

      

       2.5、WEB层设计。

             

             

              Notice：BaseAction源码

             

       2.6、页面设计

       略

       2.7、Hibernate、Spring、Struts、Log4j配置文件

      

Notice：action-Servlet源码
