原因是：
public class HibernateUtils {
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory() {
Configuration configure = new Configuration().configure();// 绑定资源文件
Properties properties = configure.getProperties();// 获取资源文件中的属性
StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder();// 服务注册对象
ServiceRegistry serviceRegistry = ssrb.applySettings(properties).build();// 注册
return configure.buildSessionFactory(serviceRegistry);// 制造sessionFactory
}
/***
* 从classpath下的hibernate.cfg.xml文件中读取信息，然后创建一个SessionFactory*@return
* SessionFactory
*/
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
这个类中的SessionFactory无法被创建，需要通过在配置文件中配置sessionFactory，才可以在服务器启动时自动创建。可以使用spring集合加载。
