要导出的Java代码

Map<String, Object> map = new HashMap<String, Object>();
        map.put("title", title);
        map.put("username", user);
        map.put("usergroup", usergroup);
        map.put("startDate", startDate);
        map.put("endDate", endDate);
        map.put("sponsorName", "Barclays");
        map.put("logo", GenericExporter.class.getResourceAsStream("/res/logo.gif"));

        // get collection datasource
        JRBeanCollectionDataSource jrBeanCollectionDataSource = new JRBeanCollectionDataSource(resultObjects);
        // compile master and sub
        InputStream masterReportStream = GenericExporter.class.getResourceAsStream(masterReport.getFilename());
        InputStream subReportStream = GenericExporter.class.getResourceAsStream(subReport.getFilename());
        InputStream subsubstream = GenericExporter.class.getResourceAsStream("/res/DetailedStockReportSub_Sub.jrxml");

        JasperReport masterCompile = JasperCompileManager.compileReport(JRXmlLoader.load(masterReportStream));
        JasperReport subCompiled = JasperCompileManager.compileReport(JRXmlLoader.load(subReportStream));
        JasperReport subsubcompiled = JasperCompileManager.compileReport(JRXmlLoader.load(subsubstream));

        // put sub report in map
        map.put("subreport", subCompiled);
        map.put("subreport2", subsubcompiled);

        // fill report
        JasperPrint jasperFillRepor = JasperFillManager.fillReport(masterCompile, map, jrBeanCollectionDataSource);




            JRPdfExporter jrPdfExporter = new JRPdfExporter();
            jrPdfExporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperFillRepor);
            jrPdfExporter.setParameter(JRExporterParameter.OUTPUT_STREAM, outpuStream);
            // run export
            jrPdfExporter.exportReport();

            return new ByteArrayInputStream(outpuStream.toByteArray());

代码执行正常，没问题。但是，如果我查看PDF，它不包含子报告中的表格。

任何帮助将不胜感激。

Answer 1

Jasper是废话。表格没有适当的控制权。它甚至无法与子报告一起正常工作。

我最终使用了iTEXt，它更好，你可以更好地控制你想要显示的数据。
