SOLVED

我做了什么来解决这个问题？

我将Persistence JPA2.1添加到库

初始错误

我遇到了这个错误:

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

不知道为什么我会遇到这个异常

主要类:

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());
       } 
     }
}

HibernateUtil 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;
}
}
