Hibernate NoSuchFieldError INSTANCE，但僅適用於Struts 1？

我是Java和Hibernate的新手（是Rails和C＃開發人員）。無論如何，我有一個測試程序，它正常工作與休眠，但我實際的Web應用程序（的Struts 1）與崩潰：Hibernate NoSuchFieldError INSTANCE，但僅適用於Struts 1？

SEVERE: Servlet.service() for servlet default threw exception java.lang.NoSuchFieldError: INSTANCE

我使用：

Hibernate 3.6.1 with Annotations

Struts 1 with Apache Tiles

C3P0 connection pool

這裏是程序，一個通常爲作品。這是主要項目的一部分。只是一個簡單的JAVA測試。

public class TestUser { 

    public static void main(String[] args) { 

    SessionFactory factory = HibernateUtil.getSessionFactory(); 
    Session session = factory.getCurrentSession(); 
    session.beginTransaction(); 

    String queryString = "from User where UserName = 'Quake'"; 
    Query query = session.createQuery(queryString); 

    User quake = (User)query.uniqueResult(); 
    session.getTransaction().commit(); 

    System.out.println(quake.getEmail()); 
    System.out.println("Active? " + quake.isActive()); 


    UserRepository userRepo = new UserRepository(); 

    System.out.println("User Quake: " + userRepo.findAll().get(0).getEmail()); 

    } 
}

工作得很好。輸出一些樣本數據。

現在，當我嘗試在Struts中做同樣的事情時，我得到了異常。這是什麼NOT WORK：

public class ListUsers extends org.apache.struts.action.Action { 

    /* forward name="success" path="" */ 
    private static final String SUCCESS = "success"; 

/** 
* This is the action called from the Struts framework. 
* @param mapping The ActionMapping used to select this instance. 
* @param form The optional ActionForm bean for this request. 
* @param request The HTTP Request we are processing. 
* @param response The HTTP Response we are processing. 
* @throws java.lang.Exception 
* @return 
*/ 
@Override 
public ActionForward execute(ActionMapping mapping, ActionForm form, 
     HttpServletRequest request, HttpServletResponse response) 
     throws Exception { 


    List<String> listMsg = new ArrayList<String>(); 

    listMsg.add("Message A"); 
    listMsg.add("Message B"); 
    listMsg.add("Message C"); 
    listMsg.add("Message D"); 

    request.setAttribute("listMsg", listMsg); 



    UserRepository userRepo = new UserRepository(); // CRASHES HERE (see HibernateUtil) 
    String email = userRepo.first().getEmail(); 


    return mapping.findForward(SUCCESS); 
    } 
}

這是我的HibernateUtil類：

public class HibernateUtil { 

    private static final SessionFactory sessionFactory = buildSessionFactory(); 

    private static SessionFactory buildSessionFactory() { 
    try { 
     // Create the SessionFactory from hibernate.cfg.xml 
     Configuration config = new Configuration(); // THIS LINE CRASHES IN STRUTS 

     // Add annotated classes 
     config.addAnnotatedClass(User.class); 

     config.configure(); 
     return config.buildSessionFactory(); 

    } catch (Throwable ex) { 
     // Make sure you log the exception, as it might be swallowed 
     System.err.println("Initial SessionFactory creation failed. WTFQNIL: " + ex); 
     throw new ExceptionInInitializerError(ex); 
    } 
    } 

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

的Configuration config = new Configuration()線在HibernateUtil的是，在Struts的崩潰行，但不是測試應用程序。

我在做什麼錯？

謝謝！

看起來你在類路徑中有幾個Hibernate jars版本。

這裏是我的JARS for Hibernate的屏幕截圖。我創建了一個全球圖書館。 http://dl.dropbox.com/u/471665/jars.png – cbmeeks 2011-02-24 16:29:48

+1指向我的一般區域。原來，我有一箇舊版本的hibernate-annotations，我不需要，因爲Hibernate 3.6帶有註釋支持？無論如何，現在的作品。 – cbmeeks 2011-02-24 18:36:10

@cbmeeks：的確，這是原因。 – axtavt 2011-02-24 19:12:13

@axtavt說得對。我知道你已經解決了這個問題，我發表了我的評論，因爲它可能對其他人有幫助。

如果您使用的是maven依賴關係，假設您已經擁有自己的hibernate依賴關係。後來，另一個依賴項（如org.codehaus.jackson或drools-spring）被添加到pom中。它可能會導致這個錯誤，因爲org.codehaus.jackson和drools-spring在不同版本的hibernate上有自己的依賴關係。在添加org.codehaus.jackson或drools-spring將解決問題時排除冬眠。

刪除這兩個依賴關係爲我工作。

這是我的Hibernate依賴。
