Hibernate环境搭建与配置方法(Hello world配置文件版)

本文实例讲述了hibernate环境搭建与配置方法。分享给大家供大家参考，具体如下：

1.下载hibernate jar包：hibernate-release-4.3.5.final，导入必要的jar包，路径为：hibernate-release-4.3.5.final\lib\required。

包含的jar包有10个。

2.建立新的java项目。

3.学习自己建立user library：

(a)项目右键——build path——configure build path——add library.
(b)选择user-library,在其中新建library，命名为hibernate。
(c)在library中加入hibernate所需要的jar包（路径为：hibernate-release-4.3.5.final\lib\required），hello world就够了，其他的还要加。

4.引入数据库的jdbc驱动。我用的mysql：mysql-connector-java-5.1.7-bin.jar

(a)创建数据库：

create database hibernate;

(b)切换数据库：

use hibernate;

(c)创建student表：

create table student(id int primary key,name varchar(20),age int);

5.建立hibernate的配置文件hibernate.cfg.xml，强烈建议在hibernate-release-4.3.5.final\documentation\manual\en-us\html_single路径下的帮助文档中copy。

地点：1.1.4. hibernate configuration。 内容修改后：

<?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>
  <!-- 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">xxx</property>
  <property name="connection.password">xxxx</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.internal.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="com/huxing/hibernate/model/student.hbm.xml"/>
 </session-factory>
</hibernate-configuration>

建立student类：

public class student {
  private int id;
  private string name;
  private int age;
 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 int getage() {
  return age;
 }
 public void setage(int age) {
  this.age = age;
 }
}

建立student的映射文件：student.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="com.huxing.hibernate.model">
 <class name="student" table="student">
  <id name="id" column="id">
  </id>
  <property name="name" type="string" column="name"/>
  <property name="age" type="int" column="age"/>
 </class>
</hibernate-mapping>

最后测试：

import org.hibernate.session;
import org.hibernate.sessionfactory;
import org.hibernate.cfg.configuration;
import com.huxing.hibernate.model.student;
public class studenttest {
 public static void main(string[] args) {
  student a = new student();
  a.setid(123);
  a.setage(32);
  a.setname("hello hibernate!");
  configuration cfg = new configuration();
  sessionfactory cf = cfg.configure().buildsessionfactory();
  session session = cf.opensession();
  session.begintransaction();
  session.save(a);
  session.gettransaction().commit();
  session.close();
  cf.close();
 }
}

希望本文所述对大家hibernate框架程序设计有所帮助。
