Hibernate 与数据库的关系是ORM关系,对象映射数据库。

那么如何通过对象对数据库进行各种对象的ddl与dml操作呢?

数据库对象操作的〈database-object ../〉+ SchemaExport

1、hibernate.cfg.xml



br />"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">



......

create

true

true



lt;/hibernate-configuration>

2、lovejk.hbm.xml



br />"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">





create table testjk(name varchar(256));






3、执行

public static void main(String[] args) throws Exception
{
//实例化Configuration,,这行代码默认加载hibernate.cfg.xml文件
Configuration conf = new Configuration().configure();
//以Configuration创建SessionFactory
SessionFactory sf = conf.buildSessionFactory();
//      //创建SchemaExport对象
SchemaExport se = new SchemaExport(conf);
//      //设置输出格式良好的SQL脚本
se.setFormat(true);
//          //设置保存SQL脚本的文件名
se.setOutputFile("d:\\1.sql");
//      //输出SQL脚本,并执行SQL脚本
se.create(true, true);
sf.close();
}

总结:简单粗暴!
