错误无法找到cfg.xml资源[hibernate.cfg.xml]

Question

当我运行createStudentDemo类时，出现以下错误：

INFO：HHH000412：Hibernate Core {5.4.11.Final}

线程“ main”中的异常org.hibernate.internal.util.config.ConfigurationException：无法找到cfg.xml资源[hibernate.cfg.xml]

在org.hibernate.boot.cfgxml.internal.ConfigLoader.loadConfigXmlResource（ConfigLoader.java:53）

在org.hibernate.boot.registry.StandardServiceRegistryBuilder.configure（StandardServiceRegistryBuilder.java:215）

在org.hibernate.cfg.Configuration.configure（Configuration.java:258）

在org.hibernate.cfg.Configuration.configure（Configuration.java:244）

在com.luv2code.hibernate.demo.CreateStudentDemo.main（CreateStudentDemo.java:15）

我不明白为什么会出现此错误

这是我的createStudentDemo类的代码：

package com.luv2code.hibernate.demo;

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

import com.luv2code.hibernate.demo.entity.Student;

public class CreateStudentDemo {

    public static void main(String[] args) {
        // create session factory

        SessionFactory factory= new Configuration()
                                .configure("hibernate.cfg.xml")
                                .addAnnotatedClass(Student.class)
                                .buildSessionFactory();


        // create session

        Session session = factory.getCurrentSession();

        try {

            //create a student object
            System.out.println("creating new student object");
            Student tempStudent = new Student("Paul", "Wall", "[email protected]");


            //start a transaction

            session.beginTransaction();

            // save the student object

            System.out.println("Saving the student...");
            session.save(tempStudent);

            //commit transaction

            session.getTransaction().commit();

            System.out.println("Done !");
        }

        finally {
            factory.close();
        }
    }

}

这是我班上的学生的代码：

package com.luv2code.hibernate.demo.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="student")
public class Student {

    public Student() {

    }
    @Id
    @Column(name="id")
    private int id;

    @Column(name="first_name")
    private String firstName;

    @Column(name="last_name")
    private String lastName;

    @Column(name="email")
    private String email;

    public Student(String firstName, String lastName, String email) {

        this.firstName = firstName;
        this.lastName = lastName;
        this.email = email;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return "Student [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + ", email=" + email + "]";
    }


}

这是我的hibernate.cfg.xml文件的代码：

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

        <!-- Set the current session context -->
        <property name="current_session_context_class">thread</property>

    </session-factory>

</hibernate-configuration>

这是我的文件的位置：

有人可以帮我吗？

您hibernate.cfg.xml应该在类路径中。将其放在src文件夹中。
