这里商品表通过shop_id一对一关联商店表，实体类属性ownerId没定义，是怎么获取到的呢？有点模糊？

package com.imooc.o2o.entity;

import java.util.Date;

public class Shop {
    private Long shopId;
    private String shopName;
    private String shopDesc;
    private String shopAddr;
    private String phone;
    private String shopImg;
    private Integer priority;
    private Date createTime;
    private Date lastEditTime;

    //-1 不可用 0.审核中 1.可用
    private Integer enableStatus;

    //超级管理员给店家提醒
    private String advice;
    private  Area area;
    private PersonInfo owner;
    private ShopCategory shopCategory;
