web工程单独使用hibernate（用于测试以及hibernate入门）

1 首先下载hibernate包地址：http://hibernate.org/orm/

2 新建web工程，添加hibernate的lib参考包（将第一步解压的文件里的lib文件夹下required文件夹下的jar包复制到web工程的webroot的web-inf的lib下）

3 文件结构如图

4 Test类用作测试效果：代码：

package com.sinosoft;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.hibernate.cfg.Configuration;public class Test {public static void main(String[] args) {    Configuration cfg=new Configuration();    cfg.configure("hibernate.cfg.xml");    @SuppressWarnings("deprecation")    SessionFactory sf=cfg.buildSessionFactory();    Session session = sf.openSession();    Transaction tx=session.beginTransaction();        Person person = new Person();    person.setName("lxy");    session.save(person);    tx.commit();    session.close();    sf.close();    }}

将Test类以java application运行即可检测效果。

5 注意事项： *<property name = "dialect">org.hibernate.dialect.OracleDialect</property>这个语句一定要和jar包驱动对应，不然会报hibernate_sequence找不到。

                 *以下报错可以忽略，仍能达成实验效果。

  *上述Test类的main方法里的

 Transaction tx=session.beginTransaction();这句意为已打开事务 如若添加tx.begin();语句则会报错。
希望大家能够调试成功。
