休眠不適用於Sql Server 2008

我是Hibernate noob。我最近開始學習Hibernate。我正在學習一個教程......但現在我迷了路。我一直在試圖解決這個問題...休眠不適用於Sql Server 2008

的hibernate.cfg.xml

    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; 
    } 




}

hibernateTest.java

package com.hibernate.dto; 

import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import org.hibernate.cfg.Configuration; 
import org.hibernate.service.ServiceRegistry; 
import org.hibernate.service.ServiceRegistryBuilder; 

public class HibernateTest { 

    public static void main(String[] args) { 

     UserDetails user = new UserDetails(); 

     user.setUserId(1); 
     user.setUserName("ahmed"); 



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

     Session session = sessionfact.openSession(); 
     session.beginTransaction(); 
     session.save(user); 
     session.getTransaction().commit(); 
     session.close(); 

    } 

}

現在當我嘗試運行它。我每次都會收到以下錯誤...但我仍然不確定它是什麼意思？請幫我...

我看着進入休眠罐子，但找不到org.hibernate.ejb.test.item

UPDATE

現在我得到這些錯誤

入住這 - > http://www.roseindia.net/hibernate/hibernateannotations/hibernate-annotations-tutorial.shtml 我得到你沒有把註釋權的感覺。 – AnujKu

你只需要嘗試不同的可能性和調試，並繼續嘗試，直到它得到解決。沒有大的錯誤 – AnujKu

正如我所看到的，您尚未在註釋中定義類的表名。 – AnujKu

我懷疑缺失的類是您正在關注的教程的一部分。爲了簡單起見，請在您的XML配置中註釋掉class-cache和collection-cache元素，並將use_query_cache屬性設置爲false。還註釋掉與緩存相關的其他任何屬性。

給定更新錯誤日誌，從XML配置中刪除hibernate.cache.region.factory_類屬性。就像我之前說過的那樣，讓代碼工作而不先緩存配置。

評論讓事情變得更加複雜。現在有三個錯誤:(線程中的異常「main」org.hibernate.HibernateException：無法實例化RegionFactory [org.hibernate.testing.cache.CachingRegionFactory] ' –

@Ahmed我編輯了我的答案。 – JamesB

我已添加新的錯誤日誌 –
