需求分析

在现有地点中解析其地点优先级,最小到区县,当前区县可指定作业优先级,当绑定优先级数据后的数据应在选择时优先展示。

行政优先级维护

采用百度地图数据行政区域编码维护,考虑到现有数据是人工维护,获取其省市区县可能不准确,所以先根据其经纬度定位后可准确获取其省市区县,然后再进行编码维护。

示例

地点北京市东城区天安门，百度坐标116.403963,39.915119

API:

https://lbsyun.baidu.com/index.php?title=webapi/district-search https://lbsyun.baidu.com/index.php?title=webapi/guide/webservice-geocoding-abroad



 Map<String, String> map = IbsBMapUtils.reverseGeocoding("116.403963", "39.915119");
                String province = map.get("province");

List<IbsBMapUtils.Districts> districts = IbsBMapUtils.regionSearch(province.substring(0, 2));
                for (IbsBMapUtils.Districts district : districts) {
                    DivisionDo divisionDo = new DivisionDo();
                    divisionDo.setProvinceCode(district.getCode());
                    divisionDo.setProvinceName(district.getName());
                    divisionDo.setWarehouseCode(locationConfigDO.getWarehouseCode());
                    List<IbsBMapUtils.Districts> districtsList = district.getDistricts();
                    if (org.apache.commons.collections.CollectionUtils.isNotEmpty(districtsList)) {
                        for (IbsBMapUtils.Districts districts2 : districtsList) {
                            divisionDo.setCityCode(districts2.getCode());
                            divisionDo.setCityName(districts2.getName());
                            List<IbsBMapUtils.Districts> districts3 = districts2.getDistricts();
                            if (org.apache.commons.collections.CollectionUtils.isNotEmpty(districts3)) {
                                for (IbsBMapUtils.Districts district3 : districts3) {
                                    divisionDo.setRegionName(district3.getName());
                                    divisionDo.setRegionCode(district3.getCode());
                                    divisionRepository.insert(divisionDo);
                                }
                            } else {
                                divisionRepository.insert(divisionDo);
                            }
                        }
                    } else {
                        divisionRepository.insert(divisionDo);
                    }
                }

当前区域指定优先级作业后数据优先展示

例如北京市有N个区,指定了N个规划路线,当东城区指定了由最近的骑手配送时，则点击东城区商家的配送线路优先展示


List<MunicipalLevel>  list = MunicipalLevelMapper.selectMunicipalLevelList("北京市-东城区");

       if(CollectionUtils.isEmpty(list)){
           return Collections.emptyList();
       } else {
	List<String> riderList = divisionMapper.getRiderByProvince("11001", "北京市","东城区");
               //错误实例
			if (CollectionUtils.isNotEmpty(riderList)) {
                   for (String riderName : riderList) {
                       List<RirderListResponse> listResponses = list.stream().filter(vo -> StringUtils.isNotEmpty(vo.getRirderName()) && vo.getRiderName().equals(riderName)).collect(Collectors.toList());
                       if (CollectionUtils.isNotEmpty(listResponses)) {
                           for (int i = 0; i < listResponses.size(); i++) {
                               RirderListResponse response = listResponses.get(i);
                               final List l = list;
                               l.set(i, l.set(j, l.get(i)));
                           }
                       }
                   }
               }

       }
       log.warn("响应{}", JSONObject.toJSONString(list));

bug修复

当前查询出东城区绑定优先级为1.2.3.4时，查询出来的顺序更新索引位置会变为4.3.2.1，且考虑到list会多个且可重复重新更改代码

List<MunicipalLevel>  list = MunicipalLevelMapper.selectMunicipalLevelList("北京市-东城区");


       if(CollectionUtils.isEmpty(list)){
           return Collections.emptyList();
       } else {
              List<String> riderList = divisionMapper.getRiderByProvince("11001", "北京市","东城区");
               riderList = riderList.stream().filter(item -> responseList.stream().map(RouteListResponse::getName).collect(Collectors.toList()).contains(item)).collect(Collectors.toList());
               Collections.reverse(riderList);
                   Collections.reverse(riderList);
                   for (int i = 0; i < riderList.size(); i++) {
                       for (MunicipalLevel res : list) {
                           if(res.getName().equals(riderList.get(i))){
                               Collections.swap(list, list.indexOf(res), i);
                           }
                       }
                   }
               }
       }

bug再次修复终极版

当存在多个优先级相同的区域路线时，会因为本身在list的位置不同，导致最后只有第一个正确，其他元素位置不正确


if(CollectionUtils.isEmpty(list)){
            return Collections.emptyList();
        } else {
              // List<String> riderList = divisionMapper.getRiderByProvince("11001", "北京市","东城区");
                //riderList = riderList.stream().filter(item -> responseList.stream().map(RouteListResponse::getName).collect(Collectors.toList()).contains(item)).collect(Collectors.toList());
                    //Collections.reverse(riderList);
                    //借助外部元素记录交换元素位置
                    if (CollectionUtils.isNotEmpty(supplierList)) {
                    int a = 0 ;
                    for (int i = 0; i < riderList.size(); i++) {
                        for (MunicipalLevel res : list) {
                            if(res.getName().equals(riderList.get(i))){
                                Collections.swap(list, list.indexOf(res), i);
                                a++;
                            }
                        }
                    }
                }
