Question

我想用JasperReports导出CSV文件。我正在使用REST，我不知道如何设置ExporterOutput。它适用于PDF / XLSX但是我无法获得CSV的解决方案。

JasperPrint jasperPrint = storageManager.generateYearAggregateXLS(id, year);
    response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
    response.setHeader("Content-Disposition", "attachment;filename=Agregaty.xlsx");
    response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");

    JRCsvExporter exporter = new JRCsvExporter();
    exporter.setExporterInput(new SimpleExporterInput(jasperPrint));

    exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(response.getOutputStream()));

    SimpleCsvReportConfiguration configuration = new SimpleCsvReportConfiguration();
    exporter.setConfiguration(configuration);
    exporter.exportReport();

在exporter.setExporterOutput我有以下问题： The method setExporterOutput(WriterExporterOutput) in the type JRAbstractExporter<CsvReportConfiguration,CsvExporterConfiguration,WriterExporterOutput,JRCsvExporterContext> is not applicable for the arguments (SimpleOutputStreamExporterOutput)

它与excel完美配合。

我找到了解决方案而且非常简单：

exporter.setExporterOutput(new SimpleWriterExporterOutput(response.getOutputStream()));

我已将 OutputStreamExporterOutput 中的编写器 OutputStreamExporterOutput 更改为 SimpleWriterExporterOutput
