java - GeoMesa Native API (Accumulo) - 多边形相交过滤器 : missing "the_geom" in SimpleFeature

Question

我正在通过 native API 将 shapefile(TM_WORLD_BORDERS-0.3.shp)中的数据提取到 geomesa(在 Accumulo 上)中。然后，我想再次使用 native Api，查询 geomesa 中包含用户给出的点(纬度、经度)的任何数据(基本上是 geomesa 中包含该点的任何多边形)。

或多或少模仿 http://docs.geotools.org/latest/userguide/library/main/filter.html 中的“问题。我点击了什么？:使用点检查多边形层”

GeoMesaQuery q = GeoMesaQuery.GeoMesaQueryBuilder.builder()
.within(-180.0,-90.0,180.0,90.0)   // needed or the query throws a null-pointer ex
.filter(ff.contains(ff.property("the_geom"), ff.literal(point)))
.build();

但是，当我运行查询时，我收到错误(累积):

我可以看到我的功能具有 *geom 类型，但不是“the_geom”类型。然后我尝试覆盖 SimpleFeatureView 'populate' 和 'getExtraAttributes' 方法，但 getExtraAttributes 不会让我绑定(bind)几何图形...(注意:我还尝试从 populate 签名中为 setAttribute 提供 gmtr，但出现相同的错误) .

GeoMesaIndex<Shapefile> index = AccumuloGeoMesaIndex.build(
                                                 config.getString("tableName"),
                                                 config.getString("zookeeperHostPort"),
                                                 config.getString("accumuloInstance"),
                                                 config.getString("user"),
                                                 config.getString("password"),
                                                 false,
                                                 new ShapefileValueSerializer(),
                                                 new SimpleFeatureView<Shapefile>() {
                                                    @Override
                                                    public void populate(SimpleFeature sf, Shapefile t, String string, byte[] bytes, Geometry gmtr, Date date) {
                                                        sf.setAttribute("the_geom", t.the_geom);
                                                 }

                                                    @Override
                                                    public List<AttributeDescriptor> getExtraAttributes() {
                                                        AttributeTypeBuilder atb = new AttributeTypeBuilder();
                                                        return Lists.newArrayList(
                                                            atb.binding(Geometry.class).buildDescriptor("the_geom")
                                                                                                                        );
                                                    }
                                                });

有错误:

综上所述，是否可以使用 GeoMesa 的 Native Api 使用过滤器进行多边形点包含检查？我无法使用 ff.property 查询几何图形(任何版本的“geom”，例如“the_geom”、“*geom”等)

Answer 1

添加为官方答案:可以使用 GeoMesa native API 进行多边形点包含检查 - 您只需确保在调用 insert here 时使用要查询的几何图形。 。然后几何图形就可以在名称“geom”下进行查询。
