hibernate 框架的搭建
方法一
1、下载需要的jar包
网址
www.hibernate.org,推荐下载hibernate-distribution-3.3.2.GA-dist.zip
2、部署jar包
解压压缩包，拷贝解压文件根目录下的hibernate3.jar以及lib目录下的required文件夹下的所有jar,slf4j-simple-1.5.2需单独下载
3、创建hibernate配置文件
再解压文件的project\etc中，拷贝hibernate.cfg.xml放在src目录下
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="dialect">
org.hibernate.dialect.MySQLDialect
</property>
<property name="connection.url">
jdbc:mysql://localhost:3306/test
</property>
<property name="connection.username">root</property>
<property name="connection.password">123456</property>
<property name="connection.driver_class">
com.mysql.jdbc.Driver
</property>
<property name="myeclipse.connection.profile">MySql</property>
<property name="show_sql">true</property>
<property name="format_sql">false</property>
<mapping resource="entity/Users.hbm.xml" />
</session-factory>
</hibernate-configuration>
4、创建实体类和实体映射文件
package entity;
public class Users implements java.io.Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String name;
private String password;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="entity.Users" table="users">
<id name="id">
<generator class="native" />
</id>
<property name="name"/>
<property name="password"/>
</class>
</hibernate-mapping>
5、使用hibernate操作数据库
package util;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibUtil {
public static SessionFactory sf=null;
public static Session session=null;
public static Configuration cfg=new Configuration().configure();
public Session getSession(){
sf=cfg.buildSessionFactory();
session=sf.openSession();
return session;
}
public void closeAll(){
if(session!=null){
session.close();
}
if(sf!=null){
sf.close();
}
}
}
方法二
平台：myeclipse 8.6
前期准备：配置数据库连接
1.打开
窗体
2.鼠标单击任意一个，点击右键->New
3.如图，点击finish
Hibernate配置
1、选择所要构建hibernate的项目，右键->MyEclipse->Add Hibernate Capabilities,如下图
2.所选项如下图,然后next
3.直接next
4.选择使用的数据库
5.可以不创建SessionFactory,点击finish
6.添加实体类和实体映射文件（注：数据库中已存在相关的表），打开起初配好的的数据库连接，选择要映射的表
7.点击右键，选择Hibernate Reverse Engineering
8.配置如图所示，next
9.直接next
10.选择表，配置如图，finish
