实体类：

public class Student {
    private int id;
    private String name;
    private int age;
    public int getAge() {
        return age;
    }
    public int getId() {
        return id;
    }
    public String getName() {
        return name;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public void setId(int id) {
        this.id = id;
    }
    public void setName(String name) {
        this.name = name;
    }
}

测试类：StudentTest
import org.hibernate.Session;
import org.hibernate.SessionFactory;

import java.util.*;

import cn.edu.jmu.hibernate.model.*;

import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.tutorial.util.HibernateUtil;

public class StudentTest {

    public static void main(String[] args) {
         Student st = new Student();
            st.setId(6);
            st.setName("哈哈");
            st.setAge(20);
            
            Session session = HibernateUtil.getSessionFactory().getCurrentSession();//报错之一：21行的。。。
            session.beginTransaction();

            session.save(st);

            session.getTransaction().commit();
    }
}
自定义类（测试类中要用到）：HibernateUtil
package org.hibernate.tutorial.util;

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
            // Create the SessionFactory from hibernate.cfg.xml
           return new Configuration().configure().buildSessionFactory(
                new StandardServiceRegistryBuilder().build() );
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

}
