利用Hibernate生产表

<mapping resource="com/zhiqi/model/Admin.hbm.xml"/><mapping resource="com/zhiqi/model/Role.hbm.xml"/><mapping resource="com/zhiqi/model/Group.hbm.xml"/><mapping resource="com/zhiqi/model/Action.hbm.xml"/>

设计1对多，多对多的关系

往数据库里添加一些数据，做好关联关系

然后

package com.zhiqi.service;import java.util.Iterator;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.junit.After;import org.junit.Before;import org.junit.Test;import com.zhiqi.model.Action;import com.zhiqi.model.Admin;import com.zhiqi.model.Group;import com.zhiqi.model.Role;import com.zhiqi.util.HibernateUtil;public class FirstTest {private SessionFactory sessionFactory=HibernateUtil.getSessionFactory();private Session session;@Beforepublic void setUp() throws Exception {session=sessionFactory.openSession(); // 生成一个session    session.beginTransaction(); // 开启事务}@Afterpublic void tearDown() throws Exception { session.getTransaction().commit(); // 提交事务 session.close(); // 关闭session}@Testpublic void firstCreateTable(){}@Testpublic void firstSetData(){}@Testpublic void firstGetData(){Admin admin1=(Admin)session.get(Admin.class, Integer.valueOf(1));Admin admin2=(Admin)session.get(Admin.class, Integer.valueOf(2));Admin admin3=(Admin)session.get(Admin.class, Integer.valueOf(3));//System.out.println(admin1);//System.out.println(admin2);//System.out.println(admin3);//System.out.println(admin1.getRole());//System.out.println(admin2.getRole());//System.out.println(admin3.getRole());//某角色的组//Role role2=(Role)session.get(Role.class, Integer.valueOf(2));////Iterator it=role2.getGroupSet().iterator();//while(it.hasNext()){//System.out.println((Group)it.next());//}//某组的权限//Group group2=(Group)session.get(Group.class, Integer.valueOf(2));//Iterator it=group2.getActionSet().iterator();//while(it.hasNext()){//System.out.println((Action)it.next());//}//某组的角色//Group group3=(Group)session.get(Group.class, Integer.valueOf(3));//Iterator it=group3.getRoleSet().iterator();//while(it.hasNext()){//System.out.println((Role)it.next());//}//角色的管理员Role role2=(Role)session.get(Role.class, Integer.valueOf(2));Iterator it=role2.getAdminSet().iterator();while(it.hasNext()){System.out.println((Admin)it.next());}}}

这样就可以用Hibernate来操作数据库了。
