人事子系统分层结构为：领域模型层（DomainModel）——数据访问层（Dao）——服务层（Sevice）——表示层（Web），在Web页面中采用了ObjectDataSource作为GridView的数据源，并为此增加了一个帮助类。
在数据访问层中充分体现了Spring.NET和NHibernate的无缝集成，只要继承HibernateDaoSupport就能很便捷的使用NHibernate，而不需要很深入了解NHibernate。

修改Config/Guushuuse.SalaryPrj.HR.config文件，新增object
<object id=”deptDao” type=”Guushuuse.SalaryPrj.HR.Dao.DeptDao, Guushuuse.SalaryPrj.HR”>
<property name=”HibernateTemplate” ref=”hibernateTemplate” />
</object>
\n
<object id=”employeeDao” type=”Guushuuse.SalaryPrj.HR.Dao.EmployeeDao, Guushuuse.SalaryPrj.HR”>
