建立Annotation版本的HelloWorld

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;
	}

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

import com.zzk.hibernate.model.Student;
