java - org.hibernate.MappingNotFoundException : resource: hibernate. cfg.xml 未找到

Question

我尝试在 MYSQL 中连接，但在尝试添加配置下一个资源:hibernate.cfg.xml 时出现错误。并有下一个错误 org.hibernate.MappingNotFoundException:资源: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

        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <mapping class="DAO.logic.User" />

    </session-factory>
</hibernate-configuration>

ProjectName.iml(我删除了很多垃圾，导入maven jetty等):

尝试将 hibernate.cfg.xml 放在 src/main/resources 下。
