单纯Hibernate环境的搭建

单纯Hibernate环境的搭建

所谓单纯Hibernate环境,是指不与Spring集成而单独使用Hibernate在完成持久层工作的环境的搭建

习惯了SSH集成的小盆友可能不太记得如何单独使用Hibernate了

搭建步骤：

1.引入JDBC驱动jar包和Hibernate的Jar包

2.在src中创建Hibernate的配置文件（使用MyEclipse的XML创建向导即可）

以下是一个典型的配置文件示例：

<?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>
<property name="myeclipse.connection.profile">mysql</property>
<property name="connection.url">
jdbc:mysql://localhost:3306/edu
</property>
<property name="connection.username">root</property>
<property name="connection.password"></property>
<property name="connection.driver_class">
com.mysql.jdbc.Driver
</property>
<property name="dialect">
org.hibernate.dialect.MySQLDialect
</property>
<property name="format_sql">true</property>
<property name="show_sql">true</property>
<property name="hbm2ddl.auto">create</property>
<mapping resource="com/edu/conf/hibernate/hbm/user.hbm.xml" />
</session-factory>赛尔号丽莎布布配招
</hibernate-configuration>

3.创建映射文件，并添加到配置文件
4.实现Dao，典型的Hibernate的初始化代码

public class BaseDao {
private static SessionFactory sf = null;
//加载SessionFactory
static {运费
sf = new Configuration()
.configure("com/edu/conf/hibernate/hiernate.xml")
.buildSessionFactory();
}
public Session getSession(){
return sf.openSession();
}
}
public class UserDao extends BaseDao{
public boolean addUser(User user){
Session session = this.getSession();
Transaction trans = session.beginTransaction();
session.save(user);
trans.commit();
return true;
}
}
