内容摘要
使用ArcGIS Server java ADF开发，如果需要空间关系查询，可以有两种办法，
一种是通过com.esri.arcgisws.SpatialFilter这个包来实现，是一种SOAP的方式，
另外一种是使用传统的AO的方式实现：com.esri.arcgis.geodatabase.SpatialFilter注意两个包的命名一样，很容易混淆。
过程描述
第一种方式的代码如下：
 

 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);
     ...
     }

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); 
    ...
    }

第二种方式代码如下：

 

 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();
     ...
     }

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();
    ...
    }

在一般的情况下，建议使用第一种方式空间查询
