Hibernate NoSuchFieldError INSTANCE但只适用于Struts 1？
我是Java和Hibernate的新手（成为Rails和C＃开发人员）。 无论如何，我有一个适用于Hibernate的测试程序，但我的实际Web应用程序（Struts 1）崩溃了：
SEVERE: Servlet.service() for servlet default threw exception java.lang.NoSuchFieldError: INSTANCE
我在用：
Hibernate 3.6.1 with Annotations
Struts 1 with Apache Tiles
C3P0 connection pool
这是实际工作的程序。 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() ); } }
工作得很好。 输出一些样本数据。
现在，当我尝试在Struts中做同样的事情时，我得到了exception。 这是不工作的 ：
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 listMsg = new ArrayList(); 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); } }
这是我的HibernateUtil类：
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; } }
HibernateUtil的Configuration config = new Configuration()行是在Struts中而不是测试应用程序崩溃的行。
这是完整的exception转储：

我究竟做错了什么？
谢谢！
看起来你在类路径中有几个版本的Hibernate jar。
删除这两个依赖对我有用。
org.hibernate hibernate-commons-annotations 3.0.0.ga runtime org.hibernate hibernate-annotations 3.3.0.ga
这些是我的hibernate依赖项。
org.hibernate hibernate-core 3.6.3.Final org.javassist javassist 3.17.1-GA asm asm-all 2.2 antlr antlr 2.7.7 org.hibernate hibernate-entitymanager 3.6.3.Final
@axtavt说的没错。 我知道你已经解决了这个问题，我发表评论，因为它可能对其他人有帮助。
如果您正在使用maven依赖项，请说您已经拥有自己的hibernate依赖项。 然后，另一个依赖项（如org.codehaus.jackson或drools-spring）被添加到pom中。 它可能会导致此错误，因为org.codehaus.jackson和drools-spring对不同版本的hibernate有自己的依赖。 当你添加org.codehaus.jackson或drools-spring解决概率时，排除hibernate。
