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