Question

我正在使用Spring Data Mongo DB并尝试执行使用Spring Data Query Method Repository，GeoJSON Near Search和QueryDSLPredicate的查询。当我提出这样的请求时：

loads/near?latitude=38.8895&longitude=-77.0353&kilometers=100&plannedStops.address.state=REEFE&page=0&size=10&sort=plannedStops.address.state,asc

Spring Data Mong DB创建以下查询，完全忽略Predicate（plannedStops.address.state = REEFE）：

03:34:30.807 [http-nio-8080-exec-7] DEBUG o.s.d.m.r.query.MongoQueryCreator - Created query Query: { "plannedStops.location" : { "$nearSphere" : { $java : Point [x=38.889500, y=-77.035300] }, "$maxDistance" : 0.01567855942887398 } }, Fields: null, Sort: { "plannedStops.address.state" : -1}

03:37:00.830 [http-nio-8080-exec-4] DEBUG o.s.data.mongodb.core.MongoTemplate - find using query: { "plannedStops.location" : { "$nearSphere" : { "x" : 38.8895 , "y" : -77.0353} , "$maxDistance" : 0.01567855942887398}} fields: null for class: class Load in collection: load

当位置对象GeoJson位于Load对象上时，这没有问题，但是当它位于PlannedStops对象中时，Spring Data Mongo DB不包含谓词。所涉及的代码如下，是否有一些我缺少的东西可以让它工作？

    @Repository
    public interface LoadRepository extends MongoRepository<Load, String>,
        QueryDslPredicateExecutor<Load> , QuerydslBinderCustomizer<QLoad> {

      Long countByPlannedStopsLocationNear(Point location, Distance distance);

      Page<Load> findByPlannedStopsLocationNear(Point location, Distance distance, Predicate predicate,
          Pageable pageable);
    }


    @Document
    @QueryEntity
    @ApiModel
    public class Load {

      @Id
      private String id;
      private List<PlannedStop> plannedStops = new ArrayList<>();
      }


    @QueryEntity
    @Document
    @ApiModel
    public class PlannedStop {

      private Address address = new Address();
      private BigDecimal longitude;
      private BigDecimal latitude;
      @JsonIgnore
      @GeoSpatialIndexed(type = GeoSpatialIndexType.GEO_2DSPHERE)
      private GeoJsonPoint location;

    }

@QueryEntity
@Document
@ApiModel
public class Address {

  private String streetAddress1;
  private String streetAddress2;
  private String city;
  private String state;
  private String zipCode;
  private String country;
}

Service Layer
      @Override
      public LoadResponse listNear(final Double longitude, final Double latitude,
          final Integer kilometers, final Predicate predicate, final Pageable pageable) {

        if ((longitude == null) || (latitude == null) || (kilometers == null)) {
          throw new IllegalArgumentException("Longitude, Latitude, and Kilometers are missing");
        }
        // Client's current location
        Point point = new Point(latitude, longitude);
        // convert feet to miles before sending to service
        Distance distance = new Distance(kilometers, Metrics.KILOMETERS);

        LoadResponse loadResponse = new LoadResponse();
        loadResponse.setCount(loadRepository.countByPlannedStopsLocationNear(point, distance));
        loadResponse.setData(Lists
            .newArrayList(loadRepository.findByPlannedStopsLocationNear(point, distance, predicate, pageable)));

        return loadResponse;

      }

Controller Layer
      public ResponseEntity<LoadResponse> listNear(
          @RequestParam(value = "longitude") final Double longitude,
          @RequestParam(value = "latitude") final Double latitude,
          @RequestParam(value = "kilometers") final Integer kilometers,
          @QuerydslPredicate(root = Load.class) final Predicate predicate,
          final Pageable pageable) {

        LoadResponse data = loadService.listNear(longitude, latitude, kilometers, predicate, pageable);

        if (data == null) {
          return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }
        return new ResponseEntity<>(data, HttpStatus.OK);
      }

Spring Data Query Method不能与GeoJson和Predicate一起使用
