从* .hbm.xml和* .cfg.xml本地化到运行所有项目的Hibernate

我是hibernate编程的初学者，所以我试图运行我的第一个项目hibernate，但它不能在任何时间运行我运行它这对SOURSE代码项目从* .hbm.xml和* .cfg.xml本地化到运行所有项目的Hibernate

此捕获project exlorer和this is the complement project explorer是源代码：

Categorie.java

package dao; 

import java.util.Date; 
import java.util.HashSet; 
import java.util.Set; 

public class Categorie { 

    private Long idCategorie; 
    private String titre, description; 
    private Date date; 
    private Set<Produit> produits = new HashSet(); 
    public Categorie() { 
     super(); 
    } 

    public Categorie(String titre, String description, Date date) { 
     super(); 
     this.titre = titre; 
     this.description = description; 
     this.date = date; 
    } 

    public Long getIdCategorie() { 
     return idCategorie; 
    } 

    public void setIdCategorie(Long idCategorie) { 
     this.idCategorie = idCategorie; 
    } 

    public String getTitre() { 
     return titre; 
    } 

    public void setTitre(String titre) { 
     this.titre = titre; 
    } 

    public String getDescription() { 
     return description; 
    } 

    public void setDescription(String description) { 
     this.description = description; 
    } 

    public Date getDate() { 
     return date; 
    } 

    public void setDate(Date date) { 
     this.date = date; 
    } 

}

Produit.java

package dao; 

public class Produit { 

    private Long idProduit; 
    private String nom, description; 
    private Double prix; 

    public Produit() { 
     super(); 
    } 

    public Produit(String nom, String description, Double prix) { 
     super(); 
     this.nom = nom; 
     this.description = description; 
     this.prix = prix; 
    } 

    public Long getIdProduit() { 
     return idProduit; 
    } 

    public void setIdProduit(Long idProduit) { 
     this.idProduit = idProduit; 
    } 

    public String getNom() { 
     return nom; 
    } 

    public void setNom(String nom) { 
     this.nom = nom; 
    } 

    public String getDescription() { 
     return description; 
    } 

    public void setDescription(String description) { 
     this.description = description; 
    } 

    public Double getPrix() { 
     return prix; 
    } 

    public void setPrix(Double prix) { 
     this.prix = prix; 
    } 

}

Service.java

package dao; 

import org.hibernate.Session; 
import util.HibernateUtil; 
public class Services { 

    public void addProduit(Produit p){ 
     Session session = HibernateUtil.getSessionFactory().getCurrentSession(); 
     session.beginTransaction(); 
     session.save(p); 
     session.getTransaction().commit(); 
    } 
}

test.java

package dao; 

public class Test { 

    public static void main(String[] args) { 
     // TODO Auto-generated method stub 
     Services s =new Services(); 
     Produit p = new Produit("PC", "Sony viao", (double)7000); 
     s.addProduit(p); 
    } 

}

HibernateUtil.java

package util; 


import org.hibernate.*; 
import org.hibernate.cfg.*; 

public class HibernateUtil { 
    public static final SessionFactory sessionFactory; 

    static { 
     try { 
      // Création de la SessionFactory à partir de hibernate.cfg.xml 
      sessionFactory = new Configuration().configure("Hibernate.cfg.xml").buildSessionFactory(); 
     } catch (Throwable ex) { 
      // Make sure you log the exception, as it might be swallowed 
      System.err.println("Initial SessionFactory creation failed." + ex); 
      throw new ExceptionInInitializerError(ex); 
     } 
    } 

    // public static final ThreadLocal session = new ThreadLocal(); 

    public static SessionFactory getSessionFactory() { 
     return sessionFactory; 
    } 
}

就从这里它的Java代码，从现在它是个XML：

Categorie.hbm.xml

<?xml version="1.0"?> 
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 
<hibernate-mapping> 

    <class name="dao.Categorie" table="CATEGORIE"> 
     <id name="idCategorie" column="ID_CATEGORIE">

     </id> 
     <nom name="titre" column="TITRE"></nom> 
     <description name="description" column="DESCRIPTION"></description> 
     <prix name="date" column="DATE"></prix> 
     <set name="produit" table="CAT_PROD">

      <many-to-many class="dao.Produit" column="ID_PRODUIT"></many-to-many> 
     </set> 
    </class> 

</hibernate-mapping>

Produit.hbm.xml

<?xml version="1.0"?> 
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</id> 
<nom name="nom" column="NOM"></nom> 
<description name="description" column="DESCRIPTION"></description> 
<prix name="prix" column="PRIX"></prix> 

</class> 

</hibernate-mapping>

的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"> 

<hibernate-configuration> 
    <session-factory> 

     <!-- Database connection settings --> 
     <property name="connection.driver_class">com.mysql.jdbc.Driver</property> 
     <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property> 
     <property name="connection.username">root</property> 
     <property name="connection.password"></property>

     <!-- Drop and re-create the database schema on startup --> 

     <property name="hbm2ddl.auto">create</property> 

     <mapping resource="dao/Categorie.hbm.xml" /> 
     <mapping resource="dao/Produit.hbm.xml" /> 

    </session-factory> 
</hibernate-configuration>

这是从控制台erreurs

的问题是在你的hbm.xml文件，这需要与<property name="更换<nom name="，请参阅here样品HBM文件。
