1 设置好配置文件,主要是有JDBC的连接字符串
Hibernate.cfg.xml
<!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="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://127.0.0.1/test</property>
<property name="connection.username">root</property>
<property name="connection.password">admin</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hbm2ddl.auto">create</property>
<mapping resource="cn/itcase/hibernate/domain/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>
数据对象配置文件
User.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.itcase.hibernate.domain">
<class name="User" table="user">
<id name="id">
<generator class="native" />
</id>
<property name="name"/>
<property name="birthday" />
</class>
</hibernate-mapping>
数据对象类
User.Java
package cn.itcase.hibernate.domain;
import java.util.Date;
public class User {
private int id;
private String name;
private Date birthday;
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 Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
}
测试文件
Main.Java
package cn.itcast.hibernate;
import java.util.Date;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import cn.itcase.hibernate.domain.User;
public class Base {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Configuration cfg=new Configuration();
cfg.configure();
SessionFactory sf=cfg.buildSessionFactory();
Session s=sf.openSession();
Transaction tx=s.beginTransaction();
User user=new User();
user.setBirthday(new Date());
user.setName("myname");
s.save(user);
tx.commit();
s.close();
System.out.println("end");
}
}
