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 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);
}
}
