1、导入jar包

hibernate.jar
antlr-2.7.6.jar
commons-collections-3.1.jar
jta-1.1.jar
dom4j-1.6.1.jar
javassist-3.4.GA.jar
slf4j-api-1.5.2.jar
slf4j-log4j12-1.5.2.jar
如果使用C3P0数据源实现数据库连接：c3p0-0.9.0.4.jar
如果使用mysql数据库，Mysql JDBC驱动： mysql-connector.jar

2、写配置文件

建立一个User实体类，测试用。

package cn.itcast.hibernate.domain;import java.util.Date;public class User {private long id;private String name;private Date birthday;public long getId() {return id;}public void setId(long 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;}}

写User.hbm.xml配置文件：

<?xml version="1.0"?><!DOCTYPE hibernate-mapping PUBLIC        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping package="cn.itcast.hibernate.domain"><class name="User" table="itcast_user"><id name="id"><generator class="native" /></id><property name="name" /><property name="birthday" /></class></hibernate-mapping>

写Hibernate主配置文件hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?><!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><!-- 1，数据库连接信息 --><property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property><property name="connection.url">jdbc:mysql:///rowsy</property><property name="connection.driver_class">com.mysql.jdbc.Driver</property><property name="connection.username">root</property><property name="connection.password">root</property><!-- 2，其他配置 --><property name="show_sql">true</property><property name="hbm2ddl.auto">update</property><!-- 3，导入映射文件 --><mapping resource="cn/itcast/hibernate/domain/User.hbm.xml" /></session-factory></hibernate-configuration>

3、测试

写一个测试类：

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 {public static void main(String[] args) {SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();Session session = sessionFactory.openSession();User user = new User();user.setBirthday(new Date());user.setName("ronnie");Transaction transaction=session.beginTransaction();session.save(user);transaction.commit();session.close();}}

4、运行成功！
