我正在Jasper Report使用Java.
我有
主报告contains子报告contains子报告
我遇到的问题是主报告显示子报告，但子报告不显示其子报告。

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());
代码执行良好，没问题。但是，如果我查看 PDF，它不包含子报表中的表格。
任何帮助将不胜感激。
