系统管理_部门管理：
|-增删改查
|-页面效果显示
=====================================================================
架子搭建：
1、创建action
2、struts.xml，注意替换的是选中区域中role.
3、页面
4、第3步中的departmentAction，spring中没有，要添加注解。
5、创建service层
6、注入service
注意：注入的是service 而不是serviceImpl。
7、service层添加注解和事务
8、创建dao
=====================================================================
功能实现：
1、action
2、service
3、serviceImpl
4、jsp页面
（1）删除不用的链接
（2）路径替换
（3）列表：修改循环
添加：修改表单
修改：修改与添加页面相似 及 隐藏字段
列表：
添加：
修改：
