hibernate3.3.2学习札记（二）

hibernate3.3.2学习笔记（二）
写一个annotation版的，不废话了，先加入三个jar包一个是hibernate-annotations.jar，ejb3-persistence.jar，hibernate-commons-annotations.jar，如图

一、建立一个teacher表，有id，name,title
二、建立一个Teacher类，代码如下

import javax.persistence.Entity;import javax.persistence.Id;@Entitypublic class Teacher {private int id;private String name;private String title;public String getTitle() {return title;}public void setTitle(String title) {this.title = 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;}}

三、在hibernate.cfg.xml中加入如下

<mapping name="code">public class TeacherTest {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubTeacher teacher = new Teacher();teacher.setId(3);teacher.setName("wang");teacher.setTitle("教授");Session session = new AnnotationConfiguration().configure().buildSessionFactory().openSession();session.beginTransaction();session.save(teacher);session.beginTransaction().commit();session.close();}}

运行测试类会出现Hibernate: insert into Teacher (name, title, id) values (?, ?, ?)
