属性hibernate.cfg.xml

Question

如何将属性从hibernate.cfg.xml作为字符串加载到我的java程序？

我想用这个属性创建IDataBaseTester，或者告诉我从hibernate.cfg.xml创建IDataBaseTester的另一种方法

用于创建会话的HibernateUtil

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            return new AnnotationConfiguration().configure().buildSessionFactory();

        }
        catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public static void shutdown() {
        // Close caches and connection pools
        getSessionFactory().close();
    }

}

您不能在Hibernate 4中使用AnnotationConfiguration，只需使用Configuration。

从hibernate.cfg.xml获取属性

Configuration configuration = new Configuration().configure();
Properties properties = configuration.getProperties();

或

StandardServiceRegistryBuilder registryBuilder = 
        new StandardServiceRegistryBuilder().configure();
Map map = registryBuilder.getSettings();

或者您可以尝试使用ConfigLoader
