建议是有一点点是一点点基础的人又没有hibernate基础和经验的人比较适合(所谓一点点基础是最起码不要我介绍一些配置文件的什么的)注意我用的JDBC驱动cominettdsTdsDriver
大家一起努力学习吧
建立PO对象
建PO对象CustomerOrder以及它们的hibernate配置文件

上面的PO已经建立完成下面是一个测试类

public class Test {
SessionFactory sessionFactory = new Configuration(nfigure()addClass(

public void saveCustomer(Customer customer) throws Exception {

public void testmethod()throws Exception

}
}
ok下面是一个hibernate的配置hibernatecfgxml(位于应用目录下面)
