マッピング（RESOURCE）が見つかりません

Question

みんな私はHibernateで新しく、私はこんにちは世界のアプリの仕事をするのに苦労しています。以下では、私のコードと同様に例外を掲載します。誰かが他のエラーを見つけて、「将来の」問題から私を救うことを願っています。

コード：

package org.arpit.javapostsforlearning; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.Id; 

@Entity(name = "User_table") 
public class User { 

    @Id 
    int userId; 

    @Column(name = "User_Name") 
    String userName; 

    String userMessage; 

    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 String getUserMessage() { 
     return userMessage; 
    } 

    public void setUserMessage(String userMessage) { 
     this.userMessage = userMessage; 
    } 

} 

この：

package org.arpit.javapostsforlearning; 

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

public class HibernateMain { 
    public static void main(String[] args) 
    { 
     Configuration configuration=new Configuration(); 
     configuration.configure(); 
     configuration.addClass(org.arpit.javapostsforlearning.User.class); 

     ServiceRegistry sr= new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build(); 
     SessionFactory sf=configuration.buildSessionFactory(sr); 

     User user1=new User(); 
     user1.setUserName("Arpit"); 
     user1.setUserMessage("Hello world from arpit"); 

     User user2=new User(); 
     user2.setUserName("Ankita"); 
     user2.setUserMessage("Hello world from ankita"); 

     Session ss=sf.openSession(); 

     ss.beginTransaction(); //saving objects to session 
     ss.save(user1); 
     ss.save(user2); 
     ss.getTransaction().commit(); 
     ss.close(); 

    } 

}

XMLSは、srcフォルダの下に格納されています。 <mapping class="User.hbm.xml"/>：ここ

Answer 1

のスクリーンショットです。しかし、あなたはリソースを使用しています。そのクラスをマップするときにクラスを使用できますが、リソースをマップする必要があります。だからちょうど <mapping resource="User.hbm.xml"/>
