異常線程 「main」 org.hibernate.MappingException：未知實體：bitronix.examples.hibernate.entities.User

Question

我Eclipse控制檯

Exception in thread "main" org.hibernate.MappingException: Unknown entity: bitronix.examples.hibernate.entities.User 

我的hibernate.cfg.xml在得到以下異常好比：

<hibernate-configuration> 
    <session-factory> 
     <property name="hibernate.connection.driver_class">org.postgresql.Driver</property> 
     <property name="hibernate.connection.password">postgres</property> 
     <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/bitronixH4</property> 
     <property name="hibernate.connection.username">postgres</property> 
     <property name="hibernate.connection.dialect">org.hibernate.dialect.PostgreSQLDialect</property> 
     <property name="hibernate.hbm2ddl.auto">create</property> 
     <mapping resource="bitronix/examples/hibernate/entities/User.hbm.xml" /> 
    </session-factory> 
</hibernate-configuration> 

我Test.java類就像

package bitronix.examples.hibernate.entities; 

public class Test { 
    public static void main(String[] args) { 
     Configuration configuration = new Configuration(); 
     configuration.configure("hibernate.cfg.xml"); 
     ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder() 
       .applySettings(configuration.getProperties()).build(); 
     SessionFactory sf1 = new Configuration() 
       .buildSessionFactory(serviceRegistry); 
     Session session = sf1.openSession(); 
     session.beginTransaction(); 
     User user = new User(); 
     user.setName("rrr"); 
     session.save(user); 
     session.getTransaction().commit(); 
    } 
} 

任何建議或幫助表示讚賞。

編輯：我User.java是這樣

public class User { 
private Integer id; 
private String name; 
//getters and setters 
} 

我User.hbm.xml是這樣

<hibernate-mapping > 
    <class name="bitronix.examples.hibernate.entities.User" table="test_user" > 
     <id name="id" type="int"> 
      <column name="id" /> 
      <generator class="identity" /> 
     </id> 
     <property name="name" type="string"> 
      <column name="name" /> 
     </property> 
    </class> 
</hibernate-mapping> 

Answer 1

的問題，很明顯，與配置代碼。您創建兩次Configuration。

只是做

SessionFactory sf1 = new Configuration().configure().buildSessionFactory(); 

我知道，它在休眠4.不贊成使用，但對Hibernate 5這是一個很好的方式。這種休眠4方法不會與Hibernate 5.工作

Hibernate 5 :- org.hibernate.MappingException: Unknown entity
