闲话不说 就开始了

 hibernate.cfg.xml:(申明 这里用的是SQL service 2005   若修改 这里修改 链接数据库    该数据库  名字LQQ  里面一张表格   在最后会发布)

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC 
 "-//Hibernate/Hibernate Configuration DTD3.0//EN" 
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<!-- Generated by MyEclipse Hibernate Tools.  -->
<hibernate-configuration>
	<session-factory>
		<property name="connection.username">sa</property>
		<property name="connection.url">
			jdbc:jtds:sqlserver://localhost:1433;DatabaseName=LQQ

		<property name="dialect">

		<property name="show_sql">true</property>
		<!-- POJO 类映射配置-->
		<mapping resource="sedion/xq/ORM/Stuinfo.hbm.xml" />
	</session-factory>
</hibernate-configuration>

 然后 贴出  HibernateSessionFactory.java:

package sedion.xq.hibernate;

import javax.swing.JOptionPane;

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

public class HibernateSessionFactory {
	private static SessionFactory sessionFactory;
	private static Configuration configuration = new Configuration();

	public HibernateSessionFactory() {
	}

	static {
		try {
			Configuration configure = configuration
					.configure("hibernate.cfg.xml");
			System.out.println(configure);
			sessionFactory = configure.buildSessionFactory();
		} catch (Exception e) {
			// TODO: handle exception
			System.out.println("HibernateSessionFactory  wrong!!");
			message("生成SessionFactory失败"+e);
		}
	}

	public static Session getSession() {
		System.out.println(sessionFactory.openSession());
		return sessionFactory.openSession();
	}
	public static void message(String mess){
		int type=JOptionPane.YES_NO_CANCEL_OPTION;
		String title="提示消息";
		JOptionPane.showMessageDialog(null,mess,title, type);
	}
}

然后 再贴出  ORM:

Stuinfo.java：

package sedion.xq.ORM;

public class Stuinfo {
	private String id;
	private String name;
	private String sex;
	private int age;
	private float weight;

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getSex() {
		return sex;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public float getWeight() {
		return weight;
	}

	public void setWeight(float weight) {
		this.weight = weight;
	}

}

 该类的映射文件如下：

Stuinfo.hbm.xml（自然可以根据这个表格  还原数据库的表格  表名：stuinfo）：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0
//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
	<class name="sedion.xq.ORM.Stuinfo" table="stuinfo">
		<id name="id" type="string">
			<column name="id" length="20" />
			<generator class="assigned" />
		</id>
		<property name="name" type="string" length="20" />
		<property name="sex" type="string" length="5" />
		<property name="age" type="integer" />
		<property name="weight" type="float" />
	</class>
</hibernate-mapping>

然后 再贴出  DAO层:

StudentDao.java：

package sedion.xq.DAO;

import java.util.List;

import javax.swing.JOptionPane;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;

import sedion.xq.ORM.Stuinfo;
import sedion.xq.hibernate.HibernateSessionFactory;
import sun.swing.UIAction;

public class StudentDao {
	private Transaction transaction;
	private Session session;
	private Query query;

	public StudentDao() {

	}

	// 显示
	public List findAllInfo() {
		session = HibernateSessionFactory.getSession();
		try {
			transaction = session.beginTransaction();
			String querysString = "from Stuinfo";
			query = session.createQuery(querysString);
			List<Stuinfo> list = query.list();
			System.out.println(list);
			transaction.commit();
			session.close();
			return list;
		} catch (Exception e) {

			message("findInfo.error" + e);
			e.printStackTrace();
			return null;
		}
	}

	// save message

	public boolean saveInfo(Stuinfo info) {
		try {
			session = HibernateSessionFactory.getSession();
			transaction = session.beginTransaction();
			session.save(info);
			transaction.commit();
			session.close();
			return true;
		} catch (Exception e) {

			message("saveInfo.error" + e);
			e.printStackTrace();
			return false;
		}
	}

	public boolean deleteInfo(String id) {
		try {
			session = HibernateSessionFactory.getSession();
			transaction = session.beginTransaction();
			Stuinfo info = new Stuinfo();
			info = (Stuinfo) session.get(Stuinfo.class, id);
			session.delete(info);
			transaction.commit();
			session.close();
			return true;
		} catch (Exception e) {
			message("deleteInfo.error" + e);
			e.printStackTrace();
			return false;
		}
	}

	public List<Stuinfo> findInfo(String id) {
		try {
			session = HibernateSessionFactory.getSession();
			transaction = session.beginTransaction();
			query = session.createQuery("from Stuinfo stu where stu.id like?");
			query.setString(0, id);
			List<Stuinfo> list = query.list();
			System.out.println(list);
			transaction.commit();
			session.close();
			return list;
		} catch (Exception e) {
			message("deleteInfo.error" + e);
			e.printStackTrace();
			return null;
		}
	}

	public boolean updateInfo(Stuinfo info,String id) {
		try {
			System.out.println(id+"didiididid");
			session = HibernateSessionFactory.getSession();
			transaction = session.beginTransaction();
			query = session.createQuery("delete from Stuinfo stu where stu.id like?");
			query.setString(0, id);
			query.executeUpdate();
			session.saveOrUpdate(info);
			transaction.commit();
			session.close();
			return true;
		} catch (Exception e) {
			message("updateInfo.error" + e);
			e.printStackTrace();
			return false;
		}
	}

	private void message(String mess) {
		int type = JOptionPane.YES_NO_CANCEL_OPTION;
		String title = "提示消息";
		JOptionPane.showMessageDialog(null, mess, title, type);
	}

}
