【问题描述】：
我有来自 java 的 1 个子报告调用的报告，显示了详细带页面的 jasper 主报告，但未显示详细带页面的 jasper 子报告。在报告主 4 页中，第 1 和第 4 页是静态的，第 2 页显示列表，第 3 页显示子报告，但第 1、2、4 页显示空白子报告。单独生成子报告并编译两个报告，在主报告、子报告和 java 代码下方
主报告

java代码
private void masterWordReport(InfluencerManagementData data) {
final InputStream subStream = this.getClass().getResourceAsStream("/subReport.jrxml");
final InputStream stream = this.getClass().getResourceAsStream("/ChannelBuzz_Influencer_JasperReport.jrxml");
try {
List<InfluencerManagementData> influencerSubReport = data.getInfluencerSubReport();
final JRBeanCollectionDataSource bookMarkListSource = new JRBeanCollectionDataSource(data.getBookmarkedInfluencersData(), false);
final JRBeanCollectionDataSource subReportListSource = new JRBeanCollectionDataSource(influencerSubReport, false);
// Compile the Jasper report from .jrxml to .japser
final JasperReport masterReport = JasperCompileManager.compileReport(stream);
final JasperReport subReport = JasperCompileManager.compileReport(subStream);
// Adding the additional dynamic parameters to the pdf.
final Map<String, Object> parameters = new HashMap<>();
parameters.put("bookMarkList", bookMarkListSource);
parameters.put("REPORT_DIR", "C:\\Users\\Sachin\\Desktop\\ChannelBuzz\\codebase\\backend\\channelBuzz-CMT\\src\\main\\resources\\");
parameters.put("influencerSubReport", subReport);
// final JasperPrint pdfPrint = JasperFillManager.fillReport(masterReport, parameters, new JREmptyDataSource());
final JasperPrint pdfPrint = JasperFillManager.fillReport(masterReport, parameters, subReportListSource);
// JasperFillManager.fillReportToFile(masterReport,
// "C:\\Users\\Sachin\\Pictures\\Saved Pictures\\test\\master_report.jrprint", parameters, subReportListSource);
final String filePath = "C:\\Users\\Sachin\\Pictures\\Saved Pictures\\test\\";
// Export to Word
JRDocxExporter exporter = new JRDocxExporter();
exporter.setExporterInput(new SimpleExporterInput(pdfPrint));
File exportReportFile = new File(filePath+"MasterReport" + ".docx");
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(exportReportFile));
exporter.exportReport();
System.out.println("Genrating the word fle report via jasper.");
} catch (Exception e) {
e.printStackTrace();
}
}
我尝试了所有解决方案，但没有显示请检查此代码中是否缺少某些内容
我想在主报告中显示子报告，我想显示 4 页子报告
