config.ConfigurationException: 找不到 cfg.xml 资源 [hibernate.cfg.xml]

问题描述

我正在构建一个休眠应用程序，它可以从数据库中创建、修改和查询表。该项目运行得很好，没有出现这个错误，当我现在尝试运行它时，我突然发现了这个错误。 'hibernate.cfg.xml' 放置在 'src' 文件夹中，如下所示。我在 Netbeans Apache IDE 12.2 上运行它（不确定这是否相关）。

MainApp.java

package hiberApp;

import util.HiberUtil;
import org.hibernate.SessionFactory;

/*

 */
public final class MainApp {
    
    private static final SessionFactory SESSION_FACTORY = HiberUtil.getSessionFactory(HiberUtil.Mapping.ANN);

    public static void main(String[] args) {
        
//        final DataLoad dataLoad = new DataLoad();
//        dataLoad.createData(SESSION_FACTORY);
//        final DataQueries dataQueries = new DataQueries();
//        dataQueries.showAll(SESSION_FACTORY);
       
    }
}

HiberUtil.java

package util;

import model.*;
import java.io.File;
import static java.lang.Math.log;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public final class HiberUtil {
    
//     static Logger log = LoggerFactory.getLogger(HiberUtil.class); 
    /**

    public enum Mapping {
       /**

        */
       XML,/**

       ANN;
    } 
    /**

    public static SessionFactory getSessionFactory(Mapping mapping) {
   
        switch(mapping){
            case XML:
                return(getXMLSessionFactory());
            case ANN:
                return(getANNSessionFactory());
            default:
               return(getXMLSessionFactory());
        }  
    }
  
    public static SessionFactory getXMLSessionFactory() {
        try {
            File mappingDir = new File("src\\xmlMaps");
            Configuration config = new Configuration().configure();

            config.setProperty("hibernate.show_sql","false");
            config.addDirectory(mappingDir);
            SessionFactory sf = config.buildSessionFactory();
                   
//            log.trace("Session Factory created "+java.time.LocalDate.Now());
           
            return (sf);
        }
        catch (Throwable ex) {
          
            System.err.println("Initial SessionFactory creation Failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

 public static SessionFactory getANNSessionFactory() {
        try {
            Configuration config = new Configuration().configure();
            config.setProperty("hibernate.show_sql","false");
                      
            config.addAnnotatedClass(Coach.class)
            .addAnnotatedClass(Matches.class)
            .addAnnotatedClass(Person.class)

            .addAnnotatedClass(Position.class)
            .addAnnotatedClass(Stadium.class)
            .addAnnotatedClass(Team.class);
            SessionFactory sf = config.buildSessionFactory();

            throw new ExceptionInInitializerError(ex);
        }
    }

}

错误：
