校园商铺-4店铺注册功能模块-11店铺类别区域信息的获取
在js中用到的getshopinitinfo还未实现，现在实现这个方法
var initUrl = '/o2o/shopadmin/getshopinitinfo';//获取店铺的初始信息，还未定义
1 店铺类别
1.1 dao层
package com.csj2018.o2o.dao;

public interface ShopCategoryDao {
List<ShopCategory> queryShopCategory(@Param("shopCategoryCondition") ShopCategory shopCategoryCondition);
List<ShopCategory> queryAllShopCategory();
}
1.2 店铺类别mapper

### 1.4 店铺类别Service层
```#java
package com.csj2018.o2o.service;
import java.util.List;
import org.apache.ibatis.annotations.Param;
import com.csj2018.o2o.entity.ShopCategory;
public interface ShopCategoryService {
List
}
### 1.5 Service实现层
```#java
package com.csj2018.o2o.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.csj2018.o2o.dao.ShopCategoryDao;
import com.csj2018.o2o.entity.ShopCategory;
import com.csj2018.o2o.service.ShopCategoryService;
@Service
public class ShopCategoryServiceImpl implements ShopCategoryService{
@Autowired
private ShopCategoryDao shopCategoryDao;
@Override
public List<ShopCategory> getShopCategoryList(ShopCategory shopCategoryCondition) {
// TODO Auto-generated method stub
return shopCategoryDao.queryShopCategory(shopCategoryCondition);
}
}
1.6 Service验证

1.8验证controller层
浏览器打开地址：http://127.0.0.1:18080/o2o/shopadmin/getshopinitinfo
{"shopCategoryList":[{"shopCategoryId":2,"shopCategoryName":"咖啡","shopCategoryDesc":"咖啡奶茶有咖啡","shopCategoryImg":"kafei.png","priority":0,"createTime":null,"lastEditTime":null,"parent":null}],"success":true,"areaList":[{"areaId":2,"areaName":"南苑","priority":7,"createTime":null,"lastEditTime":null},{"areaId":3,"areaName":"北苑","priority":5,"createTime":null,"lastEditTime":null},{"areaId":1,"areaName":"东苑","priority":1,"createTime":null,"lastEditTime":null}]}
2.前端页面
3.修改店铺类别的mapper
对于店铺类别来说，我们希望所有的店铺都保存在二级类别下面。
主页是由一级类别组成，如二手市场、美容美发、美食饮品、休闲娱乐等
点击二级市场，展示二级类别，如二手车辆、二手书籍。店铺会存储在二级类别下面
