Java Hibernate NoSuchFieldError实例，但仅使用Struts 1？

我不熟悉Java和Hibernate（作为Rails和C#开发者）。无论如何，我有一个测试程序，可以与Hibernate配合使用，但我的实际web应用程序（Struts 1）会因以下原因崩溃：

严重：Servlet默认值的Servlet.service（）引发异常 java.lang.NoSuchFieldError:实例

我正在使用：

Hibernate 3.6.1及其注释

Struts 1与Apache互动程序

C3P0连接池

这是实际运行的程序。这是主要项目的一部分。只是一个简单的JAVA测试

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() );

  }
}

很好用。输出少量样本数据

现在，当我尝试在Struts中做同样的事情时，我得到了一个例外。这就是不起作用的东西：

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);
  }
}

HibernateUtil

中的

Configuration config=new Configuration（）

行是Struts中崩溃的行，而不是测试应用程序

以下是完整的异常转储：

谢谢

类路径中似乎有多个版本的Hibernate JAR。

@axtavt说得对。 我知道你已经解决了这个问题，我发表我的评论，因为这可能对其他人有所帮助

如果您使用的是maven依赖项，那么假设您已经有了自己的hibernate依赖项。后来，另一个依赖项（如org.codehaus.jackson或droolsspring）被添加到pom中。这可能会导致此错误，因为org.codehaus.jackson和drools spring对不同版本的hibernate有自己的依赖关系。添加org.codehaus.jackson或drools时排除hibernate spring将解决此问题
