Hibernate configuredSession factory：null

Question

所有我在日志中收到以下消息：
2013-05-14 01：32：47,079} ABSOLUTE {INFO org.hibernate.cfg.Configuration} 1 {：2074 - HHH000041：已配置的SessionFactory：null

我的应用最终因为太多连接而失败了。我有一种令人难以忘怀的感觉，这些都是相关的。我已经读过这个了;在这个网站上，但我无法真正找到解决方案。这是我的SessionFactoryUtil和我的hibernate.cfg.xml的代码。任何指针都将非常感激。

public class SessionFactoryUtil {

private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;

private static SessionFactory configureSessionFactory() 
        throws HibernateException {

    Configuration configuration = new Configuration();
    configuration.configure();
    serviceRegistry = new ServiceRegistryBuilder()
            .applySettings(configuration.getProperties())
            .buildServiceRegistry();

    sessionFactory = configuration.buildSessionFactory(serviceRegistry);

    return sessionFactory;
}


public static SessionFactory getInstance() {
    return configureSessionFactory();
    //return sessionFactory;
}

public Session getCurrentSession() {
    return sessionFactory.getCurrentSession();
}

public static void close() {
    if (sessionFactory != null) {
        sessionFactory.close();
        sessionFactory = null;
    }
}

}

Answer 1

Configured SessionFactory: null没问题。那是因为你在程序启动后初始化会话工厂。

我认为问题是<property name="conneciton.provider_class">中的错误输入，应该是<property name="connection.provider_class">。
