第一次Hibernate測試給出錯誤[編輯]

Question

我是Hibernate初學者用戶，我創建了一個非常簡單的應用程序來測試它！ 但我得到這個錯誤在控制檯：

Initial SessionFactory creation failed.org.hibernate.HibernateException: Dialect class not found: org.openmeetings.app.hibernate.utils.MySQL5MyISAMDialect 
Exception in thread "main" java.lang.ExceptionInInitializerError 
    at util.HibernateUtil.buildSessionFactory(HibernateUtil.java:20) 
    at util.HibernateUtil.<clinit>(HibernateUtil.java:10) 
    at DAO.services.addProduit(services.java:9) 
    at test.main(test.java:11) 
Caused by: org.hibernate.HibernateException: Dialect class not found: org.openmeetings.app.hibernate.utils.MySQL5MyISAMDialect 
    at org.hibernate.dialect.DialectFactory.buildDialect(DialectFactory.java:81)

    at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1292) 
    at util.HibernateUtil.buildSessionFactory(HibernateUtil.java:15) 
    ... 3 more 

我的測試類：

import DAO.services; 
import DAO.Produit; 

public class test { 

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

     services s = new services(); 
     Produit p = new Produit("PC","Sony Vaio",(double)7500); 
     s.addProduit(p); 

    } 

} 

的hibernate.cfg.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

     session.beginTransaction(); 
     session.save(p); 
     session.getTransaction().commit(); 

    } 

} 

最後2班m y對象（產品和分類）及其配置文件！

您認爲什麼可能是此錯誤的來源？

謝謝:)

Answer 1

的方言與MySQL的MyISAM數據（如果這是你所擁有的）應該是：

org.hibernate.dialect.MySQLMyISAMDialect
