客户端flex利用blazeds调用后台AO实现编辑数据

 

 

客户端flex利用blazeds调用后台AO实现编辑数据

--> 测试 环境： Eclipse Java EE 平台、 flex builder 、 Tomcat6.x 、 Adobe BlazeDS\

 Arcserver for java platform

--> 创建名为 “FlexToRemote” 的 Web 项目(基于BlazeDS，具体步骤掠过参加另一篇日志)；

--> 导入 ArcObject.jar （路径： %ARCGIS_HOME%java/lib ） ；

服务器 后台用AO 添加point 的代码 两个java类(PointDS.java和AOEditDS.java)如下：

package wlh;

import com.esri.arcgis.server.ServerConnection;

import com.esri.arcgis.server.*;

import com.esri.arcgis.system.ServerInitializer;

import com.esri.arcgis.carto.*;

import com.esri.arcgis.geodatabase.*;

import com.esri.arcgis.geometry.*;

import com.esri.arcgis.system.*;

public class AOEditDS {

    private String password = "1314525" ;

    private String user = "Administrator" ;

    private String domain = "pcwlhgis" ;

    private String host = "pcwlhgis" ;

    private String servicesName = "XIAMEN" ;

    private static  ServerConnection conn = null ;

    private static IServerContext serverContext = null ;

    private static IServerObjectManager som = null ;

    private static MapServer mapserver = null ;

    private static IMap maps = null ;  

   public void initServer(){ /** * 连接到 ArcGIS Sever */

try {

     new ServerInitializer().initializeServer( domain , user , password );

     conn = new ServerConnection();

    conn .connect( host );

     som = conn .getServerObjectManager();

     serverContext = som .createServerContext( servicesName , "MapServer" ); 

     mapserver =(MapServer) serverContext .getServerObject();         

     maps = mapserver .getMap( mapserver .getDefaultMapName());

     System. out .print( " 已连接到 ArcGIS Sever" );

     } catch (Exception e){

         e.printStackTrace();

         mapserver = null ;

         maps = null ;

         som = null ; }   }

   public boolean AddPoint(PointDS pointds){ /* 执行添加点的操作 , 传入的参数对象 PointDS * */

             // 先判断 Server 的连接状态

          if ( maps == null || mapserver == null || som == null || serverContext == null || conn == null )

                      this .initServer();

         if ( maps == null || mapserver == null || som == null || serverContext == null || conn == null )

         {

                      System. out .print( " 不能连接到 ArcGIS Server!" ); return false ;   

         }

         try {

           IFeatureLayer pFeatLayer=(IFeatureLayer) serverContext .createObject(FeatureLayer.getClsid());

           pFeatLayer=(IFeatureLayer) maps .getLayer(pointds.getLayerIndex());

           IFeatureClass pfeatureclass=pFeatLayer.getFeatureClass();

           IPoint point=(IPoint) serverContext .createObject(Point.getClsid());        

           point.setX(pointds.getX());       

           point.setY(pointds.getY());                

           point.setSpatialReferenceByRef( maps .getSpatialReference());

           IDataset dataset= new IDatasetProxy(pfeatureclass);                   

           IWorkspaceEdit pWorkspaceEdit= new IWorkspaceEditProxy(dataset.getWorkspace());

           pWorkspaceEdit.startEditing( true );

           pWorkspaceEdit.startEditOperation();                                      

           IFeatureBuffer FeatureBuffer = pfeatureclass.createFeatureBuffer();

           IFeatureCursor featureCursor = new FeatureCursor(pfeatureclass.IFeatureClass_insert( true ));

           FeatureBuffer.setShapeByRef((IGeometry) point);                                         

           java.util.Map hashmap=pointds.getHashmap();                                                     

        if (hashmap != null ){

              for (Object o : hashmap.keySet()){

            String field = String.valueOf(o);

            FeatureBuffer.setValue(FeatureBuffer.getFields().findField(field), hashmap.get(o));                                    

             }                 

         }

           featureCursor.insertFeature(FeatureBuffer);                                      

           featureCursor.flush();                                                  

           pWorkspaceEdit.stopEditOperation();

           pWorkspaceEdit.stopEditing( true );                  

           System. out .print( "\n 点已添加！ " );          

           Cleaner.release(point); // release Point of AO

           mapserver .refreshServerObjects();

           serverContext .releaseContext();

         } catch (Exception e) {

               e.printStackTrace(); mapserver = null ; maps = null ;

                   som = null ; return false ;     }                 

            return true ; }    }

 

 

 

package wlh;

public class PointDS {

    public double x ;

    public double y ;

    public int   layerIndex ;

    public java.util.Map hashmap ;

    public java.util.Map getHashmap() {

               return hashmap ;

    }

    public void setHashmap(java.util.Map hashmap) {

               this . hashmap = hashmap;

    }

    public double getX() {

               return x ;

    }

    public void setX( double x) {

               this . x = x;

    }

    public double getY() {

               return y ;

    }

    public void setY( double y) {

               this . y = y;

    }

    public int getLayerIndex() {

               return layerIndex ;

    }

    public void setLayerIndex( int layerIndex) {

               this . layerIndex = layerIndex;

    }

}

 

配置remoting-config.xml

客户端Flex 部分就两个文件，首先是和Java 相对应的“PointDS.as ”：然后是界面主文件mxml

package wlh

{

    import mx.controls.List;

    [ Bindable ]

   [RemoteClass(alias= "wlh.PointDS" )]

    public class PointDS

   {

       public function PointDS()

       {      }

    public var x:Number;

    public var y:Number;

    public var layerIndex:int;

    public var hashmap:Object;

    }

 }

 

 

利用[RemoteClass （alias="" ）] 元数据映射Java 端的FlexGroup 对象，注意这里的成员名一定要一致。

运行出现

SecurityError:Error#2048: 安全沙箱冲

突 :http://localhost:8081/FlexToRemote/FlexToRemote-debug/FlexToRemote.swf 不能从

http://pcwlhgis:8399/arcgis/rest/services/XIAMEN/MapServer?f=json 加载数据。

解决

运行成功
