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。
