我的bean工厂类，bean被填充但是，主报告类字段显示但是子报告列表没有显示，请帮助，我已经长了一些白头发试图解决这个问题

   List<InvoiceDTO> iList = new getData();


  String masterReportFileName = "/home/johnson3yo/Desktop/shop/evesi.jrxml";
  String subReportFileName = "/home/johnson3yo/Desktop/shop/evis_sub.jrxml";
  JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(iList);

   JasperReport jasperMasterReport = JasperCompileManager .compileReport(masterReportFileName);
   JasperReport jasperSubReport = JasperCompileManager .compileReport(subReportFileName);

   Map<String, Object> parameters = new HashMap<String, Object>();
     parameters.put("subreportParameter", jasperSubReport);
 JasperPrint jp =    JasperFillManager.fillReport(jasperMasterReport, parameters, beanColDataSource);
    byte[] val = JasperExportManager.exportReportToPdf(jp);

Answer 1

我能够通过将jrxml编译为jasper来解决它，愚蠢的我。

jasper子报表未显示在JRBeanCollectionDataSource
