hibernate Annotation 注解形式 实例 事务 hibernate.cfg.xml

实体类：

import javax.persistence.Entity;
import javax.persistence.Id;


@Entity
public 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：

 <mapping resource="com/model/foo.hbm.xml"/>

<mapping class = "com.model.foo.hbm.xml"/>

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();
		
		
	}

}
