初始SessionFactory创建失败：java.lang.NoClassDefFoundError：javax / persistence / EntityListeners

Question

解决

  

我将Initial SessionFactory creation failed: java.lang.NoClassDefFoundError: javax/persistence/NamedStoredProcedureQuery 添加到了库

内心错误已解决，但现在我另一个：

Initial SessionFactory creation failed: java.lang.NoClassDefFoundError: javax/persistence/EntityListeners

有什么想法吗？

我有错误：

public class Main {

/**
 * @param args the command line arguments
 */
    public static void main(String[] args) {
       GenericDAO clienteDAO = new GenericDAO();
       List<Cliente> list = clienteDAO.getAll(Cliente.class);
       System.out.println(list.size());
       for(Cliente c : list)
         {System.out.println("-> " + c.getNombre());
       } 
     }
}

不知道为什么我会得到那个例外

主要类：

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {
    try {
        // Create the SessionFactory from standard (hibernate.cfg.xml) 
        // config file.
        sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
    } catch (Throwable ex) {
        // Log the exception. 
        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }
}

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

HibernateUtil 类：

我的 hibernate.cfg.xml

hibernate-jpamodelgen-1.2.0.Final.jar

库（我还添加了从评论中下载的hibernate-jpa-2.0-api-1.0.1.Final.jar）

我不知道为什么我会收到这个错误。 如果你问我，我已经添加了drop 1 [] -- result: [] 。 希望可以有人帮帮我。感谢

Answer 1

点击以下链接下载hibernate-jpa-2.0-api-1.0.1.Final.jar并将其放入项目库中，希望您的应用程序能正常运行。

http://repo1.maven.org/maven2/org/hibernate/javax/persistence/hibernate-jpa-2.0-api/1.0.1.Final/hibernate-jpa-2.0-api-1.0.1.Final.jar

Answer 2

我遇到了同样的问题。在我的情况下， hibernate-jpa-2.1-api-1.0.0.Final.jar 解决了这个问题，以及hibernate-core.jar，hibernate-validator.jar，hibernate-commons-annotations.jar和hibernate-entitymanager.jar
