org.hibernate.UnknownEntityTypeException: Unable to locate persister: com.hibernate2.pojo.News at org.hibernate.internal.SessionFactoryImpl.locateEntityPersister(SessionFactoryImpl.java:797)

使用的是hibernate5的方法:

ServiceRegistry serviceRegistry =
new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();

没有获得导致配置文件中信息:

<mapping resource="com/hibernate2/pojo/News.hbm.xml"/>

添加:

Configuration configuration = new Configuration().configure();
configuration.addResource("com/hibernate2/pojo/News.hbm.xml");
ServiceRegistry serviceRegistry =
new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();

暂时解决;

或者使用hibernate4的方法

ServiceRegistry serviceRegistry =
new ServiceRegistryBuilder().applySettings(configuration.getProperties())
.buildServiceRegistry();
