personidcardoperation.java

一款仿msdn聊天程序,用java编写,很好用!

package org.lxh.hibernate.demo04.oper;

import java.util.List;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.cfg.Configuration;
import org.lxh.hibernate.demo04.pojo.IDCard;
import org.lxh.hibernate.demo04.pojo.Person;

public class PersonIDCardOperation {
	private Session session = null;

	public PersonIDCardOperation() {
		this.session = new Configuration().configure().buildSessionFactory()
				.openSession();
	}

	// 先插入一个用户
	public void insert(Person per) {
		this.session.save(per);
		this.session.beginTransaction().commit();
	}

	public void update(Person per) {
		this.session.update(per);
		this.session.beginTransaction().commit();
	}
	
	public void delete(String id)
	{
		String hql = "DELETE FROM Person WHERE id=?" ;
		Query q = this.session.createQuery(hql) ;
		q.setString(0, id) ;
		q.executeUpdate() ;
		this.session.beginTransaction().commit() ;
	}

	// 最好再去编写一个专门用于更新身份证的操作
	public void update(IDCard ic)
	{
		this.session.update(ic) ;
		this.session.beginTransaction().commit() ;
	}
	
	public Person queryById(String id) {
		Person per = null;
		String hql = "FROM Person AS p where p.id=?";
		Query q = this.session.createQuery(hql);
		q.setString(0, id);
		List all = q.list();
		if (all.size() > 0) {
			per = (Person)all.get(0);
		}
		return per;
	}

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		PersonIDCardOperation po = new PersonIDCardOperation();
//		Person per = new Person() ;
//		per.setName("lxh");
//		per.setAge(new Integer(20));
//
//		// 准备好一张身份证
//		IDCard ic = new IDCard();
//		ic.setSerial("888888888888888");
//		ic.setExpiry(12);
//
//		per.setIdCard(ic);
//		ic.setPerson(per);
//		po.insert(per) ;
		po.delete("ff80808113106de40113106de8620001");
