The following ORM objects are defined in broadleaf: province, city, and area.

Key point: to define an ORM object in the broadleaf framework, you must first define an interface and then declare it in the persistence-unit configuration. If this parameter is not declared, the following error occurs: No persistent classes found for Query Class.

Iprovince:

import java.io.Serializable;import javax.annotation.Nonnull;public interface IProvince extends Serializable{        @Nonnull    public int getProv_Code();    @Nonnull    public String getProv_Name();}
