配置----Hibernate可配置的编程方式，驱动、URL、数据库访问岁用户名、密码等用使用Java代码手动加载！

public class ProgramQuery extends TestCase {public void test() {Configuration cfg = new Configuration().addResource("org/wxp/model/Users.hbm.xml").addResource("org/wxp/model/Dep.hbm.xml")//.addClass(org.wxp.model.Dep.class).setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect").setProperty("hibernate.connection.url", "jdbc:mysql://localhost/test").setProperty("hibernate.connection.driver_class", "com.mysql.jdbc.Driver").setProperty("hibernate.show_sql", "true").setProperty("hibernate.format_sql", "true");SessionFactory sessions = cfg.buildSessionFactory();Session session = sessions.openSession();Query query = session.createQuery("FROM Users");List list = query.list();for (Iterator iterator = list.iterator(); iterator.hasNext();) {Users users = (Users) iterator.next();System.out.println(users.getUserId() + "||" + users.getUserName()+ "||" + users.getLoginName()+"||"+users.getDep().getDepartName());}}}

注意：

如果工程中存在多个xxxx.hbm.xml或者Annotation的实体类文件，则必须全部在此加载进来（使用hibernate.cfg.xml没这个必要），否则会报错：

org.hibernate.MappingException: An association from the table tb_user refers to an unmapped class: org.wxp.model.Dep

org.wxp.model.Dep 就是你没有加载进来的类。
