设置PDF导出器的输出文件名 [英] Set output file name for PDF exporter

问题描述

我正在使用 JasperReports 5.6

我使用PDFCreator生成pdf。

我的pdf生成成功，但我无法设置名称到该PDF文件。

I am using JasperReports 5.6
I generate pdf using PDFCreator.
My pdf is generated successfully, but i can't set name to that PDF file.

PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet();
printRequestAttributeSet.add(MediaSizeName.ISO_A4);
PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet();
printServiceAttributeSet.add(new PrinterName("PDFCreator", null));   
JRPrintServiceExporter exporter = new JRPrintServiceExporter(); 
exporter.setExporterInput(new SimpleExporterInput(tempFileName));
SimplePrintServiceExporterConfiguration configuration = new SimplePrintServiceExporterConfiguration();
configuration.setPrintRequestAttributeSet(printRequestAttributeSet);
configuration.setPrintServiceAttributeSet(printServiceAttributeSet);
configuration.setDisplayPageDialog(false);
configuration.setDisplayPrintDialog(false);
exporter.setConfiguration(configuration);   
exporter.exportReport();

我的pdf名称是使用PDFCreator工具设置的。
我想通过该pdf文件的名称。

由于 exporter.setParameter（JRExporterParameter.OUTPUT_FILE_NAME，d：/adc.pdf）; 方法现在弃用。

请告诉我解决方法如何设置文件名

My pdf name are set using that PDFCreator tool
I want to pass the name to that pdf file.
Since exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "d:/adc.pdf"); method is now deprecated.
Please tell me solution how to set that out file name

推荐答案

我不知道认为有一种方法可以将文件名传递给PDFCreator，因为整个想法是它是一个虚拟打印机。因此，对于发送文档的程序，它可能正在某个物理打印机上打印，因此输出文件名将无关紧要。

I don't think there's a way to pass a file name to PDFCreator, because the whole idea is that it is a virtual printer. So to the program that sending the document, it could be being printed on a physical printer somewhere, hence an output file name would be irrelevant.

每当我需要输出报告时作为PDF我使用 JasperExportManager ，这是一个更简单的解决方案。 exportReportToPdfFile 方法接受输出文件路径作为字符串。示例：

Whenever I need to output reports as PDFs I use JasperExportManager, which is a much simpler solution. The exportReportToPdfFile method accepts the output file path as a string. Example:

JasperPrint filledReport = JasperFillManager.fillReport("report.jrxml", params);
JasperExportManager.exportReportToPdfFile(filledReport, "report.pdf");

或者，您可以保持代码大致相同但更改 JRPrintServiceExporter 到 JRPdfExporter 。设置输出格式的新方法（现在 setParameter 已弃用）是构造 ExporterOutput 然后调用 setExporterOutput 出口商。

Alternatively, you can keep your code largely the same but change your JRPrintServiceExporter to a JRPdfExporter. The new way to set the output format (now that setParameter is deprecated) is to construct an ExporterOutput and then call setExporterOutput on your exporter.
