testmtm.java

hibernate实体映射.实体设计(两种方案),很简单的代码

package org.hibernate.mtm;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class TestMtM {

	private Session session;

	public TestMtM() {
		Configuration config = new Configuration().configure();
		SessionFactory factory = config.buildSessionFactory();
		this.session = factory.openSession();
	}

	private void insert(Tea t) {
		Transaction trans = this.session.beginTransaction();
		this.session.saveOrUpdate(t);
		trans.commit();
	}

	public static void main(String[] args) {
		TestMtM mtm = new TestMtM();
		Stu s1 = new Stu();
	
		s1.setSname("jack");
		Stu s2 = new Stu();
		s2.setSname("Tom");
		
		Tea t1 = new Tea();
		t1.setTname("TeBm");
		
		Tea t2 = new Tea();
	
		t2.setTname("TTt");
		
		t1.getS().add(s1);
		t1.getS().add(s2);
		t2.getS().add(s1);
		t2.getS().add(s2);
		mtm.insert(t1);
		mtm.insert(t2);

	}
