如何从连接表中为附加属性创建多对多的Hibernate映射？

<hibernate-mapping>
    <class name="com.example.entity.MainEntity" table="main_entity">
        <id name="id" column="id">
            <generator class="assigned"/>
        </id>
        <list name="custom_properties" table="custom_properties" lazy="true">
            <key column="main_entity_id"/>
            <list-index column="index"/>
            <one-to-many class="com.example.entity.CustomProperty"/>
        </list>
    </class>
    <class name="com.example.entity.CustomProperty" table="custom_properties">
        <id name="id" column="id">
            <generator class="assigned"/>
        </id>
        <property name="name" column="name"/>
        <property name="value" column="value"/>
    </class>
</hibernate-mapping>

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

public class HibernateUtil {
    private static SessionFactory sessionFactory;
    static {
        Configuration configuration = new Configuration();
        configuration.addAnnotatedClass(com.example.entity.MainEntity.class);
        configuration.addAnnotatedClass(com.example.entity.CustomProperty.class);
        configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
        configuration.setProperty("hibernate.connection.url", "jdbc:mysql://localhost:3306/mydatabase?useSSL=false&serverTimezone=UTC");
        configuration.setProperty("hibernate.connection.username", "your_username");
        configuration.setProperty("hibernate.connection.password", "your_password");
        sessionFactory = configuration.buildSessionFactory();
    }
    public static Session getSession() {
        return sessionFactory.openSession();
    }
}
