PrivilegeService.java
public interface PrivilegeService extends DaoSupport<Privilege> { //查询所有顶级的权限 List<Privilege> findTopList(); }
PrivilegeServiceImpl.java
@Service @Transactional public class PrivilegeServiceImpl extends DaoSupportImpl<Privilege> implements PrivilegeService{ public List<Privilege> findTopList() { return getSession().createQuery(// "FROM Privilegea p WHERE p.parent IS NULL")// .list(); } }
web.xml增加
<!-- 用于做初始化工作的监听器，一定要配置到spring的 contextConfigLocation之后，因为要用到spring的容器对象--> <listener> <listener-class>cn.itcast.oa.util.InitListener</listener-class> </listener>
懒加载
登录时加载了用户，用户关联的对象都没有加载，但在第二个请求又访问了用户关联的对象，抛懒加载异常
Privilege.hbm.xml
