package hibernateTest;
public class Info {
private int id;
private String name;
public int getId() {
return id;

主方法类:
package hibernateTest;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class MainTest {
public static void main(String[] args) {
Configuration cfg=new Configuration();
cfg.configure("hibernateTest/hibernate.cfg.xml");//加载配置文件
SessionFactory sf = cfg.buildSessionFactory();
Session session = sf.openSession();
Transaction tx=session.beginTransaction();//开启事务
Info info = new Info();
info.setName("bb");//添加信息
session.save(info);//保存信息
tx.commit();//事务提交
session.close();
sf.close();
System.out.println(info.getName());
}
}
