Java org.hibernate.MappingNotFoundException:未找到资源：hibernate.cfg.xml

我试图在MYSQL中连接，但在尝试加载项配置下一个资源：hibernate.cfg.xml时出错。并出现下一个错误org.hibernate.MappingNotFoundException:resource:hibernate.cfg.xml未找到

HibernateUtil：

package util;

   Imports

   public class HibernateUtil {
    private static SessionFactory sessionFactory;
    private static ServiceRegistry serviceRegistry;


    static{
        try {
            Configuration configuration = new Configuration();
            configuration.addResource("hibernate.cfg.xml");
            configuration.configure();
            serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
                    configuration.getProperties()).build();
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);
    } catch (HibernateException he) {
        System.err.println("Error creating Session: " + he);
        throw new ExceptionInInitializerError(he);
    }
}

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

Hibernate.cfg.xml：

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

试着把

hibernate.cfg.xml

放在

src/main/resources

是的，我的问题解决了。什么魔法？在project.iml中，我有下一行：我不确定IDEA是如何处理其内部文件的，但是

hibernate.cfg.xml

需要位于项目的类路径中，以便从代码中可见，并且默认情况下，

src/main/java

和

src/main/resources

下的所有内容都包含在类路径中
