Question

所以我有这个主要的

package Hibernate;


import java.util.List;
import org.hibernate.Session;
import org.hibernate.SessionFactory;

public class Hibernate {

/**
 * @param args the command line arguments
 */
private static SessionFactory sessionFactory = null;
public static void main(String[] args) {
    // TODO code application logic here
     Session session = null;
    try {
        try {
            sessionFactory = UtilHibernate.getSessionFactory();
            session = sessionFactory.openSession();

            List listapagos;
            listapagos = session.createNativeQuery("SELECT * FROM pagos").list();

            for (Object pagos : listapagos)
                System.out.println(pagos.toString());

            System.out.println("Finalizado.");
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    } finally {

        session.close();
    }
}
}

我只想从MySQL中的数据库中将表加载到List中，然后显示它

和HibernateUtililty类

import org.hibernate.cfg.Configuration;
import org.hibernate.SessionFactory;
import org.hibernate.*;
import org.hibernate.service.ServiceRegistry;


public class UtilHibernate {

public static final SessionFactory sessionFactory;


static {
    try {
        // Create the SessionFactory from standard (hibernate.cfg.xml) 
        // config file.
        sessionFactory = new Configuration().configure().buildSessionFactory();
    } catch (Throwable ex) {
        // Log the exception. 
        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }

}

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

所有内容都在同一个包中，包含hibernate.reveng.xml，hibernate.cfg.xml以及tables.java和hbm.xml文件。

这是我得到的错误

INFO: HHH000206: hibernate.properties not found
Initial SessionFactory creation failed.org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [hibernate.cfg.xml]
Exception in thread "main" java.lang.NullPointerException
at hibernate.Hibernate.main(Hibernate.java:42)
C:\Users\usuario\AppData\Local\NetBeans\Cache\8.1\executor-snippets\run.xml:53:   Java returned: 1

为什么它会给我这个错误，我该如何解决？

Answer 1

您需要将hibernate.cfg.xml放在resources文件夹（\ src \ main \ resources \ hibernate.cfg.xml）中

请参阅以下问题的答案： Location of hibernate.cfg.xml in project?

找不到cfg.xml资源（/hibernate.cfg.xml）
