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：
|
1
|
create database hibernate; |
(b)切换数据库：
|
1
|
use hibernate; |
(c)创建Student表：
|
1
|
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：

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

希望本文所述对大家Hibernate框架程序设计有所帮助。
