Java “错误”；未找到映射（资源）：hibernateeexposed/Person.hbm.xml；

我是Hibernate新手，我正在尝试使用IntelliJ Idea中的Maven在Java中创建一个小应用程序。 我在上面的标题中遇到了这个错误，而在堆栈中相同问题的答案直到现在都没有帮助我

这个文件“Person.hbm.xml”是什么。我必须创造它？ 一旦它是一个映射资源，Hibernate不应该自己创建它吗

当我运行我的小程序时，出现了以下错误：

Exception in thread "main" org.hibernate.boot.MappingNotFoundException: Mapping (RESOURCE) not found : HibernateExposed/Person.hbm.xml : origin(HibernateExposed/Person.hbm.xml)
    at org.hibernate.boot.spi.XmlMappingBinderAccess.bind(XmlMappingBinderAccess.java:56)

    at Main.Main.main(Main.java:16)

下面是我试图坚持的实体类：

import javax.persistence.Entity;
import java.sql.Date;

@Entity
public class Produto {


    private String nome;
    private int cod;
    private float valor;
    private Date dataValidade;

    protected Produto() {
    }

    public Produto(String nome, int cod, float valor, Date dataValidade) {
        this.nome = nome;
        this.cod = cod;
        this.valor = valor;
        this.dataValidade = dataValidade;
    }



    /*public Produto getProdutoPorNome(String nome) {

        Produto buscaResult  = //Resultado da busca.
    }
    */

    public boolean excluirProduto(int cod) {

        boolean deuCerto=false;

        return deuCerto;
    }
}

我的主要课程是：

package Main;

import Persistencia.HibernateUtils;
import ProcessoDeVenda.Produto;
import org.hibernate.Session;
import org.hibernate.SessionFactory;

import java.util.Date;

public class Main {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Session sessao;

        HibernateUtils hiber = new HibernateUtils();
        SessionFactory session = hiber.getSessionFactory();
        Produto produto;

        try {
            sessao = session.openSession();

            Date data = new Date(05, 12, 2018);
            float valor = (float) 42000.0;

            produto = new Produto("Carro", 1, valor, (java.sql.Date) data);

            System.out.println(produto.toString());

        }catch (Exception sqlException) {
            System.out.println(sqlException);
        }

    }

}

项目结构，包含hibernate.cfg.xml文件的位置

和我的hibernate.cfg.xml文件内容： 查看“映射资源”标记

org.h2.Driver
jdbc:h2:~/PDV
卢卡斯
我的通行证
1.
org.hibernate.dial.h2方言
线
org.hibernate.cache.NoCacheProvider
真的
更新

现在，我尝试直接在hibernate.cfg.xml上映射类。（为什么hibernate不自己做这个？我用的是膏油…）

我已经删除了

<mapping resource="HibernateExposed/Person.hbm.xml" />

在我的位置上，我绘制了这个类：

   <mapping class="src.main.java.ProcessoDeVenda.Produto" />

错误就变成这样了：
