需求分析
在项目中，会有两个作业范围，分别是机构作业范围和快递员作业范围，这两个作业范围的逻辑是一致的，就是在地图中进行画出范围，就是其作业范围。
实现分析
对于作业范围是一个由多个坐标点组成的多边形，并且必须是闭合的多边形，这个就比较适合用MongoDB来存储。
现在想一个实际需求，用户小王下了订单，如何找到属于该服务范围内的快递员呢？这个就需要使用MongoDB的$geoIntersects查询操作，其原理就是查找小王的位置坐标点与哪个多边形有交叉，这个就是为其服务的快递员。
ServiceScopeEntity
/*** 服务范围实体*/
@Data
@Document("sl_service_scope")
public class ServiceScopeEntity {@Id@JsonIgnoreprivate ObjectId id;/*** 业务id，可以是机构或快递员*/@Indexedprivate Long bid;/*** 类型 {@link com.sl.ms.scope.enums.ServiceTypeEnum}*/@Indexedprivate Integer type;/*** 多边形范围，是闭合的范围,开始经纬度与结束经纬度必须一样* x: 经度，y：纬度*/@GeoSpatialIndexed(type = GeoSpatialIndexType.GEO_2DSPHERE)private GeoJsonPolygon polygon;private Long created; //创建时间private Long updated; //更新时间
}/*** 服务类型枚举*/
public enum ServiceTypeEnum {ORGAN(1, "机构"),COURIER(2, "快递员");/*** 类型编码*/private final Integer code;/*** 类型值*/private final String value;ServiceTypeEnum(Integer code, String value) {this.code = code;this.value = value;}public Integer getCode() {return code;}public String getValue() {return value;}public static ServiceTypeEnum codeOf(Integer code) {return EnumUtil.getBy(ServiceTypeEnum::getCode, code);}
}ScopeService
在ScopeService中主要定义了如下方法：
- 新增或更新服务范围
- 根据主键id删除数据
- 根据业务id和类型删除数据
- 根据主键查询数据
- 根据业务id和类型查询数据
- 根据坐标点查询所属的服务对象
- 根据详细地址查询所属的服务对象
/*** 服务范围Service*/
public interface ScopeService {/*** 新增或更新服务范围** @param bid 业务id* @param type 类型* @param polygon 多边形坐标点* @return 是否成功*/Boolean saveOrUpdate(Long bid, ServiceTypeEnum type, GeoJsonPolygon polygon);/*** 根据主键id删除数据** @param id 主键* @return 是否成功*/Boolean delete(String id);/*** 根据业务id和类型删除数据** @param bid 业务id* @param type 类型* @return 是否成功*/Boolean delete(Long bid, ServiceTypeEnum type);/*** 根据主键查询数据** @param id 主键* @return 服务范围数据*/ServiceScopeEntity queryById(String id);/*** 根据业务id和类型查询数据** @param bid 业务id* @param type 类型* @return 服务范围数据*/ServiceScopeEntity queryByBidAndType(Long bid, ServiceTypeEnum type);/*** 根据坐标点查询所属的服务对象** @param type 类型* @param point 坐标点* @return 服务范围数据*/List<ServiceScopeEntity> queryListByPoint(ServiceTypeEnum type, GeoJsonPoint point);/*** 根据详细地址查询所属的服务对象** @param type 类型* @param address 详细地址，如：北京市昌平区金燕龙办公楼传智教育总部* @return 服务范围数据*/List<ServiceScopeEntity> queryListByPoint(ServiceTypeEnum type, String address);
