Я работаю с библиотекой geoTools. Моя цель — вернуть функции из geoServer. Я правильно подключен к DataStore, но не могу получить содержимое функций коллекции.
Когда я пытаюсь:
SimpleFeatureCollection collection = featureSource.getFeatures();
При отладке моего кода ответ collectionFeature
содержит cashedSize = -1
, а typeContent
содержит правильные propertyNames
, но без данных о функциях.
Я думаю, что проблема в зависимостях, но я не могу это исправить.
Это мой код:
CRS.decode("EPSG:4326", true);
// URL
StringBuilder completeUrl = new StringBuilder();
completeUrl.append(url);
completeUrl.append("/geoserver/wfs?SERVICE=wfs&version=");
completeUrl.append(version);
completeUrl.append("&REQUEST=GetCapabilities");
String getCapabilities = completeUrl.toString();
logger.info("URL" + getCapabilities);
// Connexion to WFS
Map<String, String> connectionParameters = new HashMap<String, String>();
connectionParameters.put("WFSDataStoreFactory:GET_CAPABILITIES_URL", getCapabilities);
connectionParameters.put("WFSDataStoreFactory:MAXFEATURES", "50");
DataStore dataStore = DataStoreFinder.getDataStore(connectionParameters);
SimpleFeatureSource featureSource = dataStore.getFeatureSource(layer);
SimpleFeatureCollection collection = featureSource.getFeatures();
return collection; `
