Question

使用产品：iserver10.1.2a 操作系统：win10 x64
数据类型： 文件型
问题详细描述：执行 dataExport.run() 导出操作直接jvm崩溃，使用idesktop 执行可生产，2d，3d都可以
问题重现步骤：

ExportSettingKMZ settingKMZ = new ExportSettingKMZ(dv,fileName);
DataExport dataExport = new DataExport();
ExportSettings settings = new ExportSettings();
settings.add(settingKMZ);
dataExport.setExportSettings(settings);
dataExport.run();
Runtime runtime = Runtime.getRuntime();
try {
    File file = new File(
            fileName);
    runtime.exec("explorer /n,/select, " + file.getAbsolutePath());
} catch (IOException e) {
    e.printStackTrace();
}

Answer 1

您好，请您单独下载组件产品进行使用，需要注意的是该方法只能导出4326坐标系的数据集。

坐标确认没问题，用idesktop 试了，能直接导出。问下，单独下载组件产品指的是什么

在官网下载组件产品

Answer 2

ExportSettingKMZ settingKMZ = new ExportSettingKMZ(dv,fileName);

dv 必须得是 Dataset[] datasets = {dv}; 是个数组啊，数组，传对象直接蹦；问题已解决
