內(nèi)容摘要
使用ArcGIS Server java ADF開發(fā)，如果需要空間關(guān)系查詢，可以有兩種辦法，
一種是通過com.esri.arcgisws.SpatialFilter這個包來實(shí)現(xiàn)，是一種SOAP的方式，
另外一種是使用傳統(tǒng)的AO的方式實(shí)現(xiàn)：com.esri.arcgis.geodatabase.SpatialFilter注意兩個包的命名一樣，很容易混淆。
過程描述
第一種方式的代碼如下：
?

      SpatialFilter filter = new SpatialFilter(); 
  String mapName=functionality.getMapDescription().getName();
  
  this.getWebContext().getWebGraphics().clearGraphics();
  WebPoint wPoint=(WebPoint)event.getWebGeometry().toMapGeometry(event.getWebContext().getWebMap());
  
  
   Geometry geom = AGSUtil.toAGSGeometry(wPoint);
   com.esri.arcgisws.PointN pontN = (com.esri.arcgisws.PointN)geom;
   Point aoPont = (Point)AGSUtil.createArcObjectFromStub(pontN, serverContext);
   
   filter.setFilterGeometry(geom); 
   filter.setSpatialRel(com.esri.arcgisws.EsriSpatialRelEnum.esriSpatialRelRelation); 
   filter.setWhereClause(""); 
   filter.setSearchOrder(com.esri.arcgisws.EsriSearchOrder.esriSearchOrderSpatial); 
   filter.setGeometryFieldName(""); 
   filter.setSpatialReferenceFieldName(""); 
   filter.setSpatialRelDescription(spatialType); 
   
   MapLayerInfo layerInfos[] = functionality.getLayerInfos(); 
   for(int layerIndex=0;layerIndex<layerInfos.length;layerIndex++){
    MapLayerInfo mapLayerInfo = (MapLayerInfo) layerInfos[layerIndex]; 
    Field[] fields=mapLayerInfo.getFields().getFieldArray();
    RecordSet recordSet = mapServer.queryFeatureData(mapName, layerIndex, filter); 
    ...
    }
    

第二種方式代碼如下：

?

      SpatialFilter spatialFilter= (SpatialFilter)serverContext.createObject(SpatialFilter.getClsid());
  
  WebPolygon wPgon=(WebPolygon)event.getWebGeometry().toMapGeometry(event.getWebContext().getWebMap());
  GraphicElement ge = new GraphicElement();
  ge.setGeometry(wPgon);
   ge.setSymbol(this.getWebContext().getWebQuery().getPolygonGraphicSymbol());
   this.getWebContext().getWebGraphics().addGraphics(ge);
  
   Geometry geom = AGSUtil.toAGSGeometry(wPgon);
   com.esri.arcgisws.PolygonN pgonN = (com.esri.arcgisws.PolygonN)geom;
   Polygon aoPgon = (Polygon)AGSUtil.createArcObjectFromStub(pgonN, serverContext);
   
   for(int layerIndex=0;layerIndex<pMap.getLayerCount();layerIndex++){
    ILayer layer=pMap.getLayer(layerIndex);
    FeatureLayer featureLayer=(FeatureLayer)layer;
    IFeatureClass featureClass=featureLayer.getFeatureClass();
    spatialFilter.setGeometryByRef(aoPgon);
    spatialFilter.setSpatialRel(esriSpatialRelEnum.esriSpatialRelWithin);
    spatialFilter.setGeometryField(featureClass.getShapeFieldName());
    IFeatureCursor featureCursor = featureClass.search(spatialFilter, true);
    IFeature feature = featureCursor.nextFeature();
    ...
    }
    

在一般的情況下，建議使用第一種方式空間查詢
