1)引入SSH jar文件

Struts 核心 jar

Hibernate 核心 jar

Spring

core 核心功能

web 对web模块的支持

aop aop支持

orm 对hibernate支持

jdbc/tx jdbc相关包、事务相关包

2)配置

web.xml

初始化 struts和spring功能

struts

配置请求路径与映.xml 射action的关系

Spring

IOC容器配置

bean-base.xml [共用信息]

bean-dao.xml

bean-service.xml

bean-action.xml

3)开发

entity/dao/service/action‘

实例代码

项目结构
