hibernate4.0 buildSessionFactory过时问题

1. xml改用下面方法获取session
   

Configuration cg=new Configuration().configure();

ServiceRegistry  sr = new ServiceRegistryBuilder().applySettings(cg.getProperties()).buildServiceRegistry();

SessionFactory sf = cg.buildSessionFactory(sr);

       2.annotation下

 

    Configuration cg=new Configuration().addPackage("packageName").addAnnotatedClass(XXX.class).configure();

    ServiceRegistry  sr = new ServiceRegistryBuilder().applySettings(cg.getProperties()).buildServiceRegistry();

    SessionFactory sf = cg.buildSessionFactory(sr);

---------------------------------------------------------------------------------------------------------------------------------

cg = new Configuration().configure();
ServiceRegistry  sr = new ServiceRegistryBuilder().applySettings(cg.getProperties()).buildServiceRegistry();    
sf= cg.buildSessionFactory(sr);
session = sf.openSession();

测试运行时出现的问题

hibernate.cfg.xml的表头需要与XXX.hbm.xml的表头一致 否则会报invalid configuration异常
