Question

使用产品：iobjects 11

数据类型：shape

 【代码如下】

 DatasourceConnectionInfo connectionInfo = new DatasourceConnectionInfo();

 connectionInfo.setEngineType(EngineType.VECTORFILE);

connectionInfo.setServer(getPrefixPath() + xycsShpPath);

connectionInfo.setAlias("xycsShp"); connectionInfo.setPassword("");

 Datasource ds = new Workspace().getDatasources().open(connectionInfo);

Datasets datasets = ds.getDatasets();

DatasetVector dsline = (DatasetVector) datasets.get("shx");

double nodeSnap = dsline.getTolerance().getNodeSnap();

connectionInfo.dispose(); return nodeSnap;

【报错】 Caused by: javax.management.RuntimeErrorException: 创建文件格式解析器失败 at com.supermap.data.Datasources.open(SourceFile:152) ~[com.supermap.data-11.2.0-230721-8998-104039.jar:?]
