Hibernate не видит entity. Как пофиксить?

Прошу помочь с ошибкой org.hibernate.MappingException: Unknown entity: hibernate.entity.User
Никак не могу решить, где-то что-то я проглядел
данные БД рабочие
Гуглил, chatGPT мучал
ищу проблему уже два дня, заранее спасибо

Добрый вечер.
А кто пропишет в файл конфигурации, что этот класс является entity?)

Обратите внимание на эту строку -
<mapping class="hibernate.entity.User"/>

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="connection.url">jdbc:mysql://localhost:3306/spring_course</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.username">root</property>
        <property name="connection.password">springcourse</property>
        <property name="current_session_context_class">thread</property>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
       
         <mapping class="hibernate.entity.User"/>
    </session-factory>
