切片地图服务使用Flex API编辑和更新切图

ArcGIS Flex API 2.0开始支持访问ArcGIS Server 10 的Feature Service进行编辑。

Flex：

    minWidth="955" minHeight="600"
    xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:s="library://ns.adobe.com/flex/spark"
    xmlns:mx="library://ns.adobe.com/flex/mx"
    xmlns:esri="http://www.esri.com/2008/ags" >
   
       
   
   
       
            url="http://localhost:8399/arcgis/rest/services/sde/world/MapServer"/ >
       
   
   
   
       
       
               map="{map}"
               graphicsLayer="{drawLayer}"
               drawEnd="drawTool_drawEnd(event)"/>
       
               url="http://localhost:8399/arcgis/rest/services/sde/world/FeatureServer/0"
               editsComplete="{featureLayer0_editsComplete(event)}"
               fault="trace(event)"/>
       
               url="http://localhost:8080/ArcObjectsServer/rest/update_cache"
               result="httpUpdateCache_resultHandler(event)"
               fault="trace(event)"/>

 

更新数据完成后，再通过基于ArcObjects开发的Web服务更新切图

Java：

    private String result(String objectids) {
        String result = "false";

        IServerContext serverContext = null;
        try {
            ResourceBundle rb = ResourceBundle.getBundle("wuyf.Config");

            String host = rb.getString("HOST");
            String username = rb.getString("USERNAME");
            String password = rb.getString("PASSWORD");
            String service = rb.getString("MAP_SERVER");
            int layerId = Integer.valueOf(rb.getString("LAYER_ID"));

            ServerInitializer serverInitializer = new ServerInitializer();
            serverInitializer.initializeServer(host, username, password);
            ServerConnection conn = new ServerConnection();
            conn.connect(host);

            IServerObjectManager som = conn.getServerObjectManager();
            serverContext = som.createServerContext(service, "MapServer");

            MapServer mapServer = (MapServer) serverContext.getServerObject();
            IFeatureLayer feaLayer = (IFeatureLayer) mapServer.getLayer(
                    mapServer.getDefaultMapName(), layerId);
            IFeatureClass feaClass = feaLayer.getFeatureClass();

            String mapName = mapServer.getDefaultMapName();
            Map map = (Map) mapServer.getMap(mapName);
            ILODInfos lodInfos = mapServer.getCacheDescriptionInfo(
                    map.getName()).getTileCacheInfo().getLODInfos();
            String layers = "";
            for (int i = 0, count = map.getLayerCount(); i < count; i++) {
                String layerName = map.getLayer(i).getName();
                if (layers != "") {
                    layers += ";";
                }
                layers += layerName;
            }
            String levels = "";
            for (int i = 0, count = lodInfos.getCount(); i < count; i++) {
                ILODInfo lodInfo = lodInfos.getElement(i);
                if (levels != "") {
                    levels += ";";
                }
                levels += String.format("%f", lodInfo.getScale());
            }

            String[] ids = objectids.split(",");
            String where = "";
            for (int i = 0, count = ids.length; i < count; i++) {
                if (where != "") {
                    where += " AND ";
                }
                where += "OBJECTID=" + ids[i];
            }
            QueryFilter filter = (QueryFilter) serverContext
                    .createObject(QueryFilter.getClsid());
            filter.setWhereClause(where);

            IFeatureCursor feaCursor = feaClass.search(filter, false);
            IFeature fea = feaCursor.nextFeature();
            while (fea != null) {
                IGeometry geo = fea.getShape();
                IEnvelope env = geo.getEnvelope();

                GeoProcessor gp = (GeoProcessor) serverContext
                        .createObject(GeoProcessor.getClsid());
                gp.setOverwriteOutput(true);

                ManageMapServerCacheTiles mc = new ManageMapServerCacheTiles();

                VarArray var = (VarArray) serverContext.createObject(VarArray
                        .getClsid());
                var.add(host);
                var.add(service);
                var.add(mapName);
                var.add(layers);
                var.add(levels);
                var.add("Recreate All Tiles");
                String extent =
                      String.format("%f", env.getXMin()) + " " +
                      String.format("%f", env.getYMin()) + " " +
                     String.format("%f", env.getXMax()) + " " +
                      String.format("%f", env.getYMax());
                var.add(extent);

                //注意，执行这个GP需要将soc帐号加入到agsadmin组
                IGeoProcessorResult gpResult = gp.execute(mc.getToolName() + "_" + mc.getToolboxAlias(),var, null);
                if (gp.getMessageCount() > 0) {
                    for (int i = 0, count = gp.getMessageCount(); i < count; i++) {
                        System.err.print(gp.getMessage(i));
                    }
                }

                fea = feaCursor.nextFeature();
            }

            result = "true";
        } catch (Exception ex) {
            ex.printStackTrace();
        } finally {
            try {
                serverContext.releaseContext();
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }

        return result;
    }
