Geotools - 在parces旁边

Question

我有一个问题需要帮助。我在postgis中有parces map layer，它包含多边形。该层遵循不重叠的拓扑规则。 我怎样才能获得与geotools api所选功能“旁边”的功能？ “旁边”功能的功能至少有一个相同的边缘。

例如在这张图片中，当选择特征A时，我需要获得特征B，C，D，而不是获得特征E。

任何帮助都很高兴！谢谢！

我通过此代码解决了我的问题

public static void getRoundFeature（SimpleFeature feature，SimpleFeatureSource featureSource）{     FilterFactory2 ff = CommonFactoryFinder.getFilterFactory2（）;     GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory（null）;     几何g =（几何）feature.getAttribute（“the_geom”）;

Polygon polygon = geometryFactory.createPolygon(g.getCoordinates());
//Polygon poly = (Polygon) feature;
Filter filter = ff.intersects(ff.property("the_geom"), ff.literal(polygon));
try {
    SimpleFeatureCollection featureCollection = featureSource.getFeatures(filter);
    //System.out.println("feature around: "+ featureCollection.size());
    FeatureIterator iter = featureCollection.features();
    while(iter.hasNext()){
        SimpleFeature rfeature = (SimpleFeature) iter.next();
        System.out.println("so to: "+rfeature.getAttribute("soto")+ "so thua: "+rfeature.getAttribute("sothua"));
    }

} catch (IOException e) { LOGGER.log(Level.FINER, e.getMessage(), e);
}

}
