hibernate3.6 环境搭建

今天下午弄了一个下午，终于把hibernate3.6的开发环境搭建好了，主要步骤如下：

1、新建实体类

 

public class Event {
 private int id;
 private String title;
 private Date date;
 public int getId() {
  return id;
 }
 public void setId(int id) {
  this.id = id;
 }
 public String getTitle() {
  return title;
 }
 public void setTitle(String title) {
  this.title = title;
 }
 public Date getDate() {
  return date;
 }
 public void setDate(Date date) {
  this.date = date;
 }

建立映射文件

 

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
      "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
          "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="com.hibernate.chapterone.pojo">
 <class name="Event" table="EVENTS">
 <id name="id" column="EVENT_ID">
 <generator class="native"/>
 </id>
 <property name="date" type="timestamp" column="EVENT_DATE"/>
 <property name="title"/>
 </class>
</hibernate-mapping>

 

3、新建

hibernate.cfg.xml

文件内容如下：

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
 <session-factory>
 <property name="hibernate.connection.url">
  jdbc:mysql://localhost/hibernate
 </property>
 <property name="hibernate.connection.driver_class">
  com.mysql.jdbc.Driver
 </property>
 <property name="hibernate.connection.username">root</property>
 <property name="hibernate.connection.password">vertrigo</property>
 <property name="hibernate.dialect">
  org.hibernate.dialect.MySQLDialect
 </property>
 <property name="hibernate.show_sql">true</property>
 <mapping resource="com/hibernate/chapterone/pojo/Event.hbm.xml" />
</session-factory>
</hibernate-configuration>

编写处理类：

 

public class HibernateUtil {
 private static final SessionFactory sessionFactory = buildSessionFactory();
 private static SessionFactory buildSessionFactory() {
 try {
 // Create the SessionFactory from hibernate.cfg.xml
 return new Configuration().configure().buildSessionFactory();
 }
 catch (Throwable ex) {
 // Make sure you log the exception, as it might be swallowed
 System.err.println("Initial SessionFactory creation failed." + ex);
 throw new ExceptionInInitializerError(ex);
 }
 }
 public static SessionFactory getSessionFactory() {
 return sessionFactory;
 }
}

 

public class EventManager {
 
 
public void  createtable(){
 
  Configuration cfg=new Configuration().configure();
  SchemaExport  export=new SchemaExport(cfg);
  export.create(true, true);
}
/**
 * 创建和添加数据
 * @param title
 * @param theDate
 */
private void createAndStoreEvent(String title, Date theDate) {
 Session session = HibernateUtil.getSessionFactory().getCurrentSession();
 session.beginTransaction();
 Event theEvent = new Event();
 theEvent.setTitle(title);
 theEvent.setDate(theDate);
 session.save(theEvent);
 session.getTransaction().commit();
 }
 
 public static void main(String[] args) {
  EventManager event=new EventManager();
  event.createtable();

  
 }

}

 

在src目录下，除需要加入hibernate.cfg.xml文件外，由于需要插入日志，需要添加log4j.properties文件

 

接下来就是导入的jar包了，这个问题花了我一下午的时间：

需要导入的包如下：

antlr-2.7.6.jar

commons-collections-3.1.jar

dom4j-1.6.1.jar

hibernate3.jar

javax.persistence.jar 这个包在下载的文件中是没有的，需要自己下载。可以在附件中下载,也可以通过导入用户库

javassist-3.12.0.GA.jar

jta-1.1.jar

slf4j-api-1.6.1.jar

 

有这些包，运行程序就没有问题了
