geotools查询总结+创建Point对象

5、按条件查询要素集

这里类似于mybatis的查询数据库，这里可以实现空间检索，也就是说通过经纬度图形，可以找到与它有相交的周边的所有要素。

Object geom = feature.getAttribute(geometryPropertyName);
Geometry geometry = reader.read(geom.toString());
Geometry boundary = geometry.getBoundary();
Filter filter = ff.intersects(ff.property(geometryPropertyName), ff.literal(boundary));
SimpleFeatureCollection features = sourceFeatureStore.getFeatures();
 SimpleFeatureIterator iterator = features.features();
while (iterator.hasNext()) {
      SimpleFeature next = iterator.next();
      Object geom = next.getAttribute(geometryPropertyName);
}

            GeometryBuilder builder = new GeometryBuilder();
            GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory( null );
            //SimpleFeatureType TYPE = ;
            Point p = geometryFactory.createPoint(new Coordinate(110,37));
            Point pointOnLine = polyFinder.findNearestPolygon(p);
