Question

我试图在Eclipse中的动态Web项目中加入Hibernate v4。我正在使用Maven作为依赖项。我编写了所有代码并创建了实体类并映射了xml文件，但是在构建项目时我得到了这个错误

The project was not built since its build path is incomplete. Cannot find the class file for javax.naming.Referenceable. 
Fix the build path then try building this project MyProject

我写了HibernateUtil类：

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;

public class HibernateUtil {
private static SessionFactory sessionFactory = buildSessionFactory();

private static SessionFactory buildSessionFactory() {
    try {
        if (sessionFactory == null) {
            Configuration configuration = new Configuration()
                    .configure(HibernateUtil.class
                            .getResource("/hibernate.cfg.xml"));
            StandardServiceRegistryBuilder serviceRegistryBuilder = new StandardServiceRegistryBuilder();
            serviceRegistryBuilder.applySettings(configuration
                    .getProperties());
            ServiceRegistry serviceRegistry = serviceRegistryBuilder
                    .build();
            sessionFactory = configuration
                    .buildSessionFactory(serviceRegistry);
        }
        return sessionFactory;
    } catch (Throwable ex) {
        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}

public static void shutdown() {
    getSessionFactory().close();
}
}

编辑：我在关机方法中调用getSessionFactory方法时遇到此错误。谁知道会有什么问题？

问题在于您尝试在某处使用Referenceable接口类，并且该类在构建路径上不可用。就像它说的那样，你必须修复构建路径。通过提供具有javax.naming.Referenceable的包来完成此任务。

我觉得奇怪的是为什么重写HibernateUtil类？这可能不是你想要做的事情。而且我没有解释为什么你会写自己的。

我建议忘记HibernateUtil类并开始完全使用Hibernate框架。

编译时出现Hibernate错误
