HibernateUtil工具類的使用

標籤：app   open   actor   整合   工具   cto   util   builder   style   

為了簡化代碼的重複性，使用HibernateUtil工具類對Hibernate有關的代碼進行整合

主要實現有，getSessionFactory()，getSession()，closeSession()

public class HibernateUtil {  private static final SessionFactory sessionFactory=buildSessionFactory();  private static  Session session;  private static SessionFactory buildSessionFactory(){Configuration configuration=new Configuration().configure(); //執行個體化配置ServiceRegistry serviceRegistry=new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();//產生服務登記    return configuration.buildSessionFactory(serviceRegistry);}//擷取sessionFactorypublic static SessionFactory getSessionFactory(){return sessionFactory;}//擷取sessionpublic static Session getSession(){return sessionFactory.openSession();}//關閉sessionpublic static void closeSession(){if(session!=null){session.close();}}}
