这更适用于自动化流程 .

首先从晶体输出原始字节：

ReportClientDocument reportClientDoc = new ReportClientDocument();

reportClientDoc.open(sourceReportFile, OpenReportOptions._openAsReadOnly);

ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream) reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);

//Release report.

reportClientDoc.close();

然后创建一个包含导出结果的新文件 .

File file = new File(exportedFileName);

FileOutputStream fileOutputStream = new FileOutputStream(file);

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(byteArrayInputStream.available());

int x = byteArrayInputStream.read(byteArray, 0, byteArrayInputStream.available());

byteArrayOutputStream.write(byteArray, 0, x);

byteArrayOutputStream.writeTo(fileOutputStream);

//Close streams.

byteArrayInputStream.close();

byteArrayOutputStream.close();

fileOutputStream.close();
