annotation的配置

引入jar包 hibernate-annotations.jar，ejb3-persistence.jar，hibernate-commons-annotations.jar

创建类Teacher

package com.zhaohu.hibernate.model;

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

@Entity
public class Teacher {
 public int id;
 public String name;
 public 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;
 }

}
 

创建测试类

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

import com.zhaohu.hibernate.model.Teacher;

public class TestTeacher {
 public static void main(String[] args) {
  Teacher t = new Teacher();
  t.setId(1);
  t.setName("zhaohu");
  t.setTitle("only");
  Configuration config = new AnnotationConfiguration();
  SessionFactory sf = config.configure().buildSessionFactory();
  Session session = sf.openSession();
  session.beginTransaction();
  session.save(t);
  session.getTransaction().commit();
  session.close();
  sf.close();
 }
}
 

配置hibernate.cfg.xml文件

<mapping class="com.zhaohu.hibernate.model.Teacher"/>

测试插入数据库一条语句
