一个简单的hibernate程序

1.导入hibernate所需要的jar包

2.导入数据库需要的jar包，如mysql需要mysql-connector-java-5.0-bin.jar

3,创建实体类

package cn.itcast.hibernate.domain;

import java.util.Date;

public class User {
 private int id;
 private String name;
 private Date birthday;
 public int getId() {
  return id;
 }
 public void setId(int id) {
  this.id = id;
 }
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 public Date getBirthday() {
  return birthday;
 }
 public void setBirthday(Date birthday) {
  this.birthday = birthday;
 }
}
 

4.配置usr.hbm.xml

<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC

       "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

       "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="cn.itcast.hibernate.domain">

    <class name="User">

        <id name="id" column="id">
        <generator class="native"></generator>
        </id>
       
    <property name="name"/>
        <property name="birthday"/>
    </class>

</hibernate-mapping>
 

5.配置hibernate.cfg.xml

<!DOCTYPE hibernate-configuration PUBLIC
 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
 <session-factory name="foo">
  <property name="show_sql">true</property>
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
  <property name="hibernate.connection.username">root</property>
  <property name="hibernate.connection.password">root</property>
  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
  
  <property name="hibernate.hbm2ddl.auto">create</property>
  
  <mapping resource="cn/itcast/hibernate/domain/User.hbm.xml"/>
  
 </session-factory>
</hibernate-configuration>

6.做一个简单的测试

package cn.itcast.hibernate;

import java.util.Date;

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

import cn.itcast.hibernate.domain.User;

public class Base {

 /**
  * @param args
  */
 public static void main(String[] args) {
  Configuration cfg = new Configuration();
  cfg.configure();
  SessionFactory sf = cfg.buildSessionFactory();
  Session s = sf.openSession();
  Transaction ts = s.beginTransaction();
  User u = new User();
  u.setName("小王");
  u.setBirthday(new Date());
  s.save(u);
  ts.commit();
  s.close();
  System.out.println("end");
 }

}
