Hibernate开发第一个例子

1、首先下载以下文件：slf4j-1.5.8  hibernate-distribution-3.3.2.GA-dist
2、在myEclipse中建立hibernate 的User Libraries 库：
   Window—Prefrerences—Java—Build Path—User Libraries

3、新建java项目 并引入自定义hibernate库以及操作mysql的驱动程序
   |-hibernate3.jar
   |-lib\required(全部)
   |-slf4j-1.5.8\slf4j-1.5.8\slf4j-nop-1.5.8.jar

4、建立Student.java

package org.kevin.hibernate.model; public class Student {    private int id;    private String name;    private String description;    public Student() {    }    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 String getDescription() {       return description;    }    public void setDescription(String description) {       this.description = description;    } }

5、建立模型的映射文件：
Student.hbm.xml

<?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="org.kevin.hibernate.model">     <class name="Student" table="Student">        <id name="id" column="id">            <generator class="native" />        </id>        <property name="name" />        <property name="description" />     </class> </hibernate-mapping>

6、建立hibernate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://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration>     <session-factory>         <!-- Database connection settings -->         <property name="connection.driver_class">com.mysql.jdbc.Driver</property>         <property name="connection.url">jdbc:mysql://localhost/hibernate</property>         <property name="connection.username">root</property>         <property name="connection.password">123456</property>         <!-- JDBC connection pool (use the built-in) -->         <!-- <property name="connection.pool_size">1</property> -->         <!-- SQL dialect -->         <property name="dialect">org.hibernate.dialect.MySQLDialect</property>         <!-- Enable Hibernate's automatic session context management -->         <!-- <property name="current_session_context_class">thread</property>  -->         <!-- Disable the second-level cache  -->         <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>         <!-- Echo all executed SQL to stdout -->         <property name="show_sql">true</property>         <!-- Drop and re-create the database schema on startup -->         <property name="hbm2ddl.auto">update</property>         <mapping resource="org/kevin/hibernate/model/Student.hbm.xml"/>     </session-factory> </hibernate-configuration>

7、建立测试文件

import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; import org.kevin.hibernate.model.Student; public class StudentTest {          public static void main(String[] args) {                    Student s = new Student();                    s.setId(2);                    s.setName("kevin");                    s.setDescription("description");                    Configuration cfg = new Configuration();                    SessionFactory sf = cfg.configure().buildSessionFactory();                    Session session = sf.openSession();                    session.beginTransaction();                    session.save(s);                    session.getTransaction().commit();                    session.close();          } }

以上步骤在documentation中有，可参考!
