Java “线程中出现异常”；“主要”；org.hibernate.HibernateException:运行hibernate应用程序时未找到hibernate.cgf.xml

我的Hibernate应用程序需要检索MySQL数据库中存储的数据，但我成功地将数据保存到数据库中，但检索失败

错误日志

log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.

hibernate.cfg.xml（配置文件）

DataInsertion.java（实现逻辑）

包装mypack

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class DataInsertion {

    public static void main(String[] args) {
        //new DataInsertion().insertInfo();
        new DataInsertion().getInfo();

    }

    public void insertInfo()
    {
        Configuration con = new Configuration();        //interation with hib
        con.configure("hibernate.cfg.xml");            //registering to xml

        SessionFactory SF = con.buildSessionFactory(); //creating session
        Session session = SF.openSession();           //opening new session
        DataProvider provider = new DataProvider();
        provider.setUser_id(1);
        provider.setUser_name("Goutham");
        provider.setUser_address("Hunsur");

        Transaction TR = session.beginTransaction();
        session.save(provider);
        System.out.println("Object saved successfully");
        TR.commit();                                 //saving transaction
        session.close();
        SF.close();
    }

   public void getInfo()
   {
       Configuration con = new Configuration();
       con.configure("hibernate.cgf.xml");

       SessionFactory SF = con.buildSessionFactory();
       Session session = SF.openSession();

       Object obj = session.load(DataProvider.class,new Integer(1));     //We are binding data into obj from DataProvider class
       DataProvider dp = (DataProvider) obj;                        //Typecasting into DataProvider
       System.out.println("Name:"+dp.getUser_name());
       System.out.println("Address:"+dp.getUser_address());
       session.close();
       SF.close();
   }

}

请告诉我

谢谢。

您在getInfo方法中给出了错误的名称hibernate.cgf.xml。这就是您面临问题的原因

您输入错误的文件名hibernate.cgf.xml应该是hibernate.cfg.xml

对不起，这是一个愚蠢的键入错误，我不认识。对不起，这是一个愚蠢的键入错误，我不认识。
