org.hibernate.MappingException: Неизвестный объект: model.UserDetails

Question

Я не делаю никаких комментариев об аннотации..am с использованием javax.persistence Но я didnt underastand, почему hibernate не читает мой класс UserDetail.

UserDetails.java

package model; 

import javax.persistence.Entity; 
import javax.persistence.Id; 

@Entity 
public class UserDetails { 
    @Id 
    private int userId; 
    private String userName; 

    public int getUserId() { 
     return userId; 
    } 
    public void setUserId(int userId) { 
     this.userId = userId; 
    } 
    public String getUserName() { 
     return userName; 
    } 
    public void setUserName(String userName) { 
     this.userName = userName; 
    } 

    public static void main(String[] args) { 
     System.out.println("Successfull"); 
    } 

} 

HibernateTest.java

package model; 

import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import org.hibernate.boot.registry.StandardServiceRegistryBuilder; 
import org.hibernate.cfg.Configuration; 

public class HibernateTest { 

    public static void main(String[] args) { 
     // 
     ///TODO Auto-generated method stub 

     UserDetails user = new UserDetails(); 
     user.setUserId(1); 
     user.setUserName("Sasi"); 

      Configuration configuration = new Configuration(); 
      configuration.configure("/resources/hibernate.cfg.xml"); 
     StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()); 
     SessionFactory sessionFactory = configuration.buildSessionFactory(ssrb.build()); 
     Session session = sessionFactory.openSession(); 
     session.beginTransaction(); 
     session.save(user); 
     session.getTransaction().commit(); 

     System.out.println("Successfully"); 

    } 

} 

hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?> 
<!DOCTYPE hibernate-configuration PUBLIC 
     "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
     "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

    </session-factory>

Answer 1

Пробовали ли вы? кажется, используются для других конфигурационных файлов в соответствии с разделом Configuration (1.2)

ресурсы.

Надеется, что это помогает,
