实体类：Info.java

package hibernateTest;

public class Info {
    private int id;
    private String name;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;

    }
    public void setName(String name) {
        this.name = name;
    }

}

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());
    }
