Jasper Reports генерирует пустой PDF

0 голосов
/ 22 октября 2019

Я настраиваю сервлет для генерации PDF из студии jaspersoft. Как я могу создать заполненный PDF?

Я уже пробовал много решений для генерации PDF, но PDF генерирует с пустым результатом.

Вот код для моего сервлета: 

     @WebServlet("/JasperServlet")
        public class JasperServlet extends HttpServlet {
            private static final long serialVersionUID = 1L;

    /**
     * Default constructor.
     */
    public JasperServlet() {
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
     *      response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        try {
            InputStream jrxmlInput = this.getClass().getClassLoader().getResource("payment_receipt_ar_new.jrxml").openStream();

            JasperDesign design = JRXmlLoader.load(jrxmlInput);
            JasperReport jasperReport = JasperCompileManager.compileReport(design);
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap());
            JRPdfExporter pdfExporter = new JRPdfExporter();
            pdfExporter.setExporterInput(new SimpleExporterInput(jasperPrint));
            ByteArrayOutputStream pdfReportStream = new ByteArrayOutputStream();
            pdfExporter.setExporterOutput(new SimpleOutputStreamExporterOutput(pdfReportStream));
            pdfExporter.exportReport();
            System.out.println("size: " + String.valueOf(pdfReportStream.size()) );
            response.setContentType("application/pdf");
            response.setHeader("Content-Length", String.valueOf(pdfReportStream.size()));
            response.addHeader("Content-Disposition", "inline; filename=jasper.pdf;");

            OutputStream responseOutputStream = response.getOutputStream();
            responseOutputStream.write(pdfReportStream.toByteArray());
            responseOutputStream.close();
            pdfReportStream.close();



        } catch (JRException e) { // TODO Auto-generated
            e.printStackTrace();
        }
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
     *      response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        // TODO Auto-generated method stub


    }

}

и вот здесь payment_receipt_ar_new.jrxml:

Пожалуйста, помогите мне, он генерирует пустой pdf.

Я ожидаю, что вывод покажет заполненный pdf с некоторыми статическими и параметрическими данными. Но сейчас он генерирует пустой PDF.

Если вы хотите заголовок, заголовки и т. Д., Но не детализировать диапазон, если есть пустой результат, установите атрибут WhenNoDataType = AllSectionsNoDetail. Это подтвердит, что проблема связана с тем, что из источника данных не возвращается набор результатов. https://community.jaspersoft.com/wiki/empty-report-problem
