如何使用 JasperReports 导出 CSV
How can I export CSV with JasperReports
我想用 JasperReports 导出 CSV 文件。我正在使用 REST,但我不知道如何设置 ExporterOutput。它可以与 PDF/XLSX 一起使用,但是我无法让它导出 CSV。
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()));
我已将编写器 OutputStreamExporterOutput 从 SimpleOutputStreamExporterOutput 更改为 SimpleWriterExporterOutput
