实体类：

import javax.persistence.Entity;import javax.persistence.Id;@Entitypublic class foo {		private int id;	private String name;	private String total;		@Id	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 String getTotal() {		return total;	}	public void setTotal(String total) {		this.total = total;	}}

特别要注意配置文件的申请，一般是：

使用Annotation 注解形式就要写成：

还有在实例化的时候，要写成：

Configuration configuration = new AnnotationConfiguration();

只有AnnotationConfiguration可以认识注解形式的实体类。

完整调用类：

import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.AnnotationConfiguration;import org.hibernate.cfg.Configuration;public class test1 {	/**	 * @param args	 */	public static void main(String[] args) {		// TODO Auto-generated method stub		foo s = new foo;		s.setId(1);		s.setName(2);		S.settotal(ss);				Configuration configuration = new AnnotationConfiguration();		SessionFactory sessionFactory = configuration.buildSessionFactory();		Session session = sessionFactory.openSession();				//用事务方式储存\		session.beginTransaction();		session.save(s);		session.getTransaction().commit();		session.close();				//sessionFactory也要关闭		sessionFactory.close();					}}
