无法加载hibernate.cfg.xml

Question

我正在学习hibernate教程，并面临着这个问题。这是我的密码

public class HibernateTest {
    public static void main(String[] args) {
        System.out.println(args[0]);
        User user = new User();
        user.setId(1);
        user.setName("John Smith");
        SessionFactory sessionFactory = createSessionFactory();
        Session session = sessionFactory.openSession();
        session.beginTransaction();
        session.save(user);
        session.getTransaction().commit();
    }

    public static SessionFactory createSessionFactory() {
        Configuration configuration = new Configuration();
        configuration.configure();
        ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
                configuration.getProperties()).build();
        return configuration.buildSessionFactory(serviceRegistry);
    }
}

这是我的项目结构。

但我有个例外，说

Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found
    at org.hibernate.internal.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:173)
    at org.hibernate.cfg.Configuration.getConfigurationInputStream(Configuration.java:2095)

Answer 1

从错误中可以明显看出，hibernate.cfg.xml文件不在CLASSPATH中。

Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found

要将文件保存在CLASSPATH中，可以将其移动到/src/main/resources (或)将文件的当前位置放在CLASSPATH中。

Answer 2

将文件移到src/main/resources中，在构建时将其复制到类路径中。

Answer 3

hibernate.cfg.xml必须在类路径上。这样的文件被认为是一种资源，应该放在src/main/resources下，构建工具将它放在classes文件夹中。
