简单的 Hibernate Test

Test.java

 

import org.hibernate.cfg.*;

import org.hibernate.*;

 

public class Test {

   public static void main(String[] args) throws Exception {

      Student student = new Student();

      student.setName("Jack");

      student.set...;// 设置student 对象

 

      Configuration config = new Configuration();// 1. Configuration类，读配置文件和映射文件

      //read hibernate.cfg.xml and hbm.xml

      config = config.configure();

 

      SessionFactory sf = config.buildSessionFactory();// 2. SessionFactory 工厂类 接口

      Session session = sf.openSession();// 3. Session 核心

 

      Transaction trans = session.beginTransaction();

 

      session.save(student);

      //User user = session.load(User.class,new Long(1001));

      //session.update(user);

      //session.delete(user);

 

      trans.commit();

      session.close();

   }

}
