Teacher类:

package com.zzk.hibernate.model;

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


@Entity

public class Teacher {
    private int id;
    private String name;
    private String title;
    
    @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 getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
    
    
    
}

配置文件:

        <mapping class="com.zzk.hibernate.model.Teacher"/>
         
    </session-factory>

</hibernate-configuration>


测试类:

package com.zzk.hibernate.model.test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

import com.zzk.hibernate.model.Student;

public class StudentTest {
    public static void main(String[] args) {
    	Student s = new Student();
    	s.setId(2);
    	s.setName("s1");
    	s.setAge(1);
    	
    	Configuration cfg = new Configuration();
        SessionFactory sf = cfg.configure().buildSessionFactory();
    	Session session = sf.openSession();
    	session.beginTransaction();//执行操作
        session.save(s);
        session.getTransaction().commit();//提交
        session.close();
        sf.close();
    }
}
