hibernate配置

[zuomingyu2]

Room.java Room.hbm.xml User.java User.hbm.xml 代码在后面
我save了2个User 但是只有
Hibernate: insert into t_User (age, sex, phone, address, room_id) values (?, ?, ?, ?, ?)
Hibernate: insert into t_User (age, sex, phone, address, room_id) values (?, ?, ?, ?, ?)
room_id里都为null

但是并没有 insert into Room（）自动生成表的时候t_User里有room_id这个字段
在配置文件里有这个
<mapping resource="com/User.hbm.xml" />
<mapping resource="com/Room.hbm.xml" />

public void testSave(){
		Session session=null;		
		try{
			session=HibernateSessionFactoy.getSession();
			session.beginTransaction();
			//保存对象
			
			Room room=new Room();
			room.setRoomName("听雨轩");
			
			User user1=new User();
			user1.setAddress("第1个地址");
			
			User user2=new User();
			user2.setAddress("第2个地址");
			
			session.save(user1);
			session.save(user2);
			session.getTransaction().commit();
		}catch(HibernateException e){
			if(session.getTransaction().isActive())
				session.getTransaction().rollback();
			e.printStackTrace();
		}finally{
			HibernateSessionFactoy.closeSession(session);
		}
		
	}

你在room类中没有建立与User类的关联！
