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。
