闲话不说 就开始了
web-xml：

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><property name="dialect">org.hibernate.dialect.SQLServerDialect</property><!--<property name="myeclipse.connection.profile">LoginSystem</property> --><property name="connection.password">sa</property><property name="connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property><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 exceptionSystem.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 messagepublic 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);}}

下面是6个action包里面的处理：
