AO更新操作

AO操作图形数据库，一般的增删查改，（以修改为例）如下：

IServerContext sc=null;
IWorkspaceEdit wsEdit = null;
		    	try
		    	{
			    	sc=AOUtil.getServerContext(ConfigBean.getAOIP(), ConfigBean.getAOUserName(), ConfigBean.getAOPSW(), ConfigBean.getMapService());
			    	IWorkspace ws=AOUtil.getWorkSpaceFromWF(sc, ConfigBean.getPSRUserName(), ConfigBean.getPSRPSW(), "sde.DEFAULT");
			    	IFeatureWorkspace featureWorkspace = (IFeatureWorkspace) ws;
			    	
			    	wsEdit = (IWorkspaceEdit) featureWorkspace;//设置此ws开始编辑
			    	wsEdit.startEditing(false);
			    	wsEdit.startEditOperation();
			    	
		    		IFeatureClass featureC = featureWorkspace.openFeatureClass(featureClass.toUpperCase());
			    	IQueryFilter qf = (IQueryFilter)sc.createObject(QueryFilter.getClsid());
			    				 qf.setWhereClause("ID = '"+gisID+"'");
			    	IFeatureCursor featureCursor = featureC.IFeatureClass_update(qf, false);
			    	IFields fields = featureCursor.getFields();
			    	IFeature feature =featureCursor.nextFeature();
			    	while(feature!=null){
			    		for(int i=0; i<list.size();i++){
							Element element = (Element)list.get(i);//修改数据来源，我的是XML
							String tag = element.getName();
							String value = element.getText();
							//updateFields = updateFields + tag +" = '"+ value+ "',";
							feature.setValue(fields.findField(tag), value);
						}
			    		featureCursor.updateFeature(feature);
						feature=featureCursor.nextFeature();
					}
			    	
				}catch (Exception e) {
					System.out.println(e.getMessage());
		    		logger.error("获取设备图形信息错误！"); 
				}
				finally{
					try {
						wsEdit.stopEditOperation();
						wsEdit.stopEditing(true);//保存编辑
						count = 1;
					} catch (AutomationException e) {
						e.printStackTrace();
					} catch (IOException e) {
						e.printStackTrace();
					}
					AOUtil.releaseServerContext(sc);
				}
