java代码如何通过AE将GDB转成shp

hotsaysauce2 2016-04-05 07:02:07

网上资料很少，现在可以连接到ArcgisEngine，也可以把gdb转成shp格式，但是无法解析中文，gdb出现中文的部分转成shp以后是乱码，估计方法用的不对



public static void main(String[] args) {

		System.out

				.println("Starting BrowseFileGDB - An ArcObjects SDK Developer Sample");



try {

			EngineInitializer.initializeEngine();

			AoInitialize aoInit = new AoInitialize();

			// Initialize ArcGIS license

			initializeArcGISLicenses(aoInit);

			QueryGDB qb = new QueryGDB();



			String inFGDB = "D:\\test.gdb";



			FileGDBWorkspaceFactory factory = new FileGDBWorkspaceFactory();

			Workspace workspace = new Workspace(factory.openFromFile(inFGDB, 0));

			String shapepath = "D:\\LayerData_temp";

			File dir = new File(shapepath);

			

			makeDir(dir);

			

			IWorkspaceFactory pFact = new ShapefileWorkspaceFactory();

			IWorkspace pOutWorkspace = pFact.openFromFile(shapepath, 0);

			

			IQueryFilter queryFilter = new QueryFilter();

			

			String whereSql = "\"shiCode\"='150000' and \"OBSERVE_TIME\" = \'2016/3/7 11:00:00\'";

			

			queryFilter.setWhereClause(whereSql);

			

			IEnumDataset enumDataset = workspace.getDatasets(esriDatasetType.esriDTFeatureClass);

			IDataset ds = enumDataset.next();

			

			FeatureClass featureClass = null;

			while (ds != null) {

			

				if(layerName.equals(ds.getName())){

					System.out.println(ds.getName());

					featureClass = new FeatureClass(ds);

				

				}

				ds = enumDataset.next();

			}//生成shp文件

		    qb.ExportToShapefile(featureClass,queryFilter, pOutWorkspace);

		} catch (Exception e) {

			System.out.println("Error: " + e.getMessage());

			System.out.println("Sample failed.  Exiting...");

			e.printStackTrace();

			System.exit(-1);

		}

private void ExportToShapefile(IFeatureClass pFeatureClass,IQueryFilter queryFilter,

			IWorkspace outWorkspace) {

		try {

			IDataset inDataSet = new IDatasetProxy(pFeatureClass);

			IFeatureClassName inFCName = (IFeatureClassName) inDataSet

					.getFullName();

			IDataset outDataSet = (IDataset) outWorkspace;

			IWorkspaceName outWorkspaceName = (IWorkspaceName) outDataSet

					.getFullName();

			IFeatureClassName outFCName = new FeatureClassName();

			IDatasetName dataSetName = (IDatasetName) outFCName;

			dataSetName.setWorkspaceNameByRef(outWorkspaceName);

			dataSetName.setName(pFeatureClass.getAliasName().toString());

			IFeatureDataConverter featureDataConverter = new FeatureDataConverter();

		

			featureDataConverter.convertFeatureClass(inFCName, queryFilter, null,

					outFCName, null, null, "", 1000, 0);

		} catch (Exception e) {

			e.printStackTrace();

		}
