实体类teacher

package com.luhy.hibernate.model;import javax.persistence.Entity;import javax.persistence.Id; @Entity public class Teacher {private int id;private String name;private String title;@Idpublic 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;}}

junit4测试类TeacherTest

package com.luhy.hibernate.model;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;import org.hibernate.service.ServiceRegistry;import org.hibernate.service.ServiceRegistryBuilder;import org.junit.AfterClass;import org.junit.BeforeClass;import org.junit.Test;import com.luhy.hibernate.model.Teacher;public class TeacherTest {private static SessionFactory sessionFactory = null;@BeforeClasspublic static void beforeClass(){Configuration cfg = new Configuration().configure();        ServiceRegistry serviceRegistry =new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry();sessionFactory = cfg.buildSessionFactory(serviceRegistry);}@Testpublic void testTeacherSave() {Teacher t = new Teacher();t.setId(2);t.setName("在");t.setTitle("oolk");        Session session = sessionFactory.openSession();        session.beginTransaction();               //事务开启        session.save(t);                             //保存对象        session.getTransaction().commit();        session.close();    }@AfterClasspublic static void afterClass(){sessionFactory.close();}}

工程目录结构如下图

写这个例子主要是想让新手在初学时需要注意一些技巧，像源码目录test，一般用来存放需要测试的类，还有测试类teacherTest中的静态方法 beforeClass 和 afterClass的用法
