JasperReports export to xlsx, not xls

问题

I can't find how to export a file in .xlsx in JasperReports 4.1.1. The class:

JRXlsExporter

has not a Xlsx equivalent. And i can't find a parameter to set the output format from xls to xlsx.

回答1:

The JRXlsxExporter class should be used for exporting at XLSX format.

Sample of using exporter with JasperReports prior 5.5.2 version

Till JasperReports 5.5.1 this code can be used for generating report at xlsx format:

JRMapArrayDataSource dataSource = new JRMapArrayDataSource(data);

JasperReport jasperReport = JasperCompileManager.compileReport(reportJRXMLSource);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, dataSource);

JRXlsxExporter exporter = new JRXlsxExporter();
exporter.setParameter(JRXlsExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRXlsExporterParameter.OUTPUT_FILE_NAME, outputFileName);

exporter.exportReport();

Since 5.5.2 version of library the JRAbstractExporter.setParameter(JRExporterParameter, Object) method is deprecated.

Sample of using exporter with modern JasperReports versions

In this example I used JRS 6.4.1 version:

JasperReport jasperReport;
try (InputStream inputStream = JRLoader.getResourceInputStream(jrxmlFilePath)) {
    jasperReport = JasperCompileManager.compileReport(JRXmlLoader.load(inputStream));
}
Map<String, Object> params = new HashMap<>();

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, new JREmptyDataSource());

SimpleXlsxReportConfiguration configuration = new SimpleXlsxReportConfiguration();
configuration.setOnePagePerSheet(true);
configuration.setIgnoreGraphics(false);

File outputFile = new File("output.xlsx");
try (ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
     OutputStream fileOutputStream = new FileOutputStream(outputFile)) {
    Exporter exporter = new JRXlsxExporter();
    exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
    exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(byteArrayOutputStream));
    exporter.setConfiguration(configuration);
    exporter.exportReport();
    byteArrayOutputStream.writeTo(fileOutputStream);
}

Instead of using JRExporter.setParameter method we have to use implementation of XlsReportConfiguration interface. In example above I used SimpleXlsxReportConfiguration implementation of XlsReportConfiguration for defining settings specific to JRXlsxExporter exporter.

This answer is to help users with JASPER REPORT VERSION >5.6 (latest versions), hence remove the deprecated code.

In later version >5.6 the JRXlsxExporter.setParameter(..) has been deprecated.

You should use

JRMapArrayDataSource dataSource = new JRMapArrayDataSource(data);

JasperReport jasperReport = JasperCompileManager.compileReport(reportJRXMLSource);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, dataSource);

JRXlsxExporter exporter = new JRXlsxExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
File outputFile = new File("excelTest.xlsx");
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outputFile));
SimpleXlsxReportConfiguration configuration = new SimpleXlsxReportConfiguration(); 
configuration.setDetectCellType(true);//Set configuration as you like it!!
configuration.setCollapseRowSpan(false);
exporter.setConfiguration(configuration);
exporter.exportReport();

回答3:

All you need to do is put the format in the request path, like this:

@RequestMapping( value = "/ActivityReport.xlsx", method = RequestMethod.GET )
public ModelAndView generateActivityReportXLS( HttpServletRequest request, HttpServletResponse response ) {


    List<ActivityDisplay> list = activityManager.listActivities();

    Map<String, Object> parameterMap = new HashMap<>();
    parameterMap.put( "datasource", new JRBeanCollectionDataSource( list ) );
    return new ModelAndView( "activitiesXLSView", parameterMap );
}

回答4:

JRXlsExporter is available in in JasperReports 4.5 and later versions.
