使用java工具进行CQL查询within

问题描述 投票：-1回答：1

我需要找出某地1000米范围内的所有餐馆.我的餐馆层就是 引用：餐厅位置坐标为- 76.10, 10.51

我使用以下代码

GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory();
String getCapabilities = http://localhost:8080/geoserver/ows?service=wfs&version=1.1.0&request=GetCapabilities";
Map<String, Serializable> connectionParameters = new HashMap<>();
connectionParameters.put(WFSDataStoreFactory.URL.key, getCapabilities);
WFSDataStoreFactory dsf = new WFSDataStoreFactory();
WFSDataStore dataStore = dsf.createDataStore(connectionParameters);
String types[] = dataStore.getTypeNames();

String name = "cite:restaurents";
Point point = geometryFactory.createPoint(new Coordinate(76.10, 10.51));
// Filter filter = CQL.toFilter(String.format("DWITHIN(%s, POINT(76.10
// 10.51),1000, meters)", "geom"));
FilterFactory2 filterFactory = CommonFactoryFinder.getFilterFactory2();
Filter filter = filterFactory.dwithin(filterFactory.property("the_geom"), filterFactory.literal(point),
        1000, "meters");

SimpleFeatureSource source = dataStore.getFeatureSource(name);
source.getBounds();

SimpleFeatureCollection fc = source.getFeatures(filter);

SimpleFeatureIterator itr = fc.features();
while (itr.hasNext()) {
    SimpleFeature sf = itr.next();

    System.out.println(sf);
}

异常

你可以将其设置为CQL过滤器或使用 FilterFactory 但根据你选择的方式不同，规则也不同。

你可以使用CQL（既快又简单）。

Filter filter = CQL.toFilter("dwithin(\"the_geom\","+point+", 1000, meters)");
