JasperPrint jasperPrint = JasperFillManager.fillReport(filePath+"/Invoice.jasper", reportParameters, new JREmptyDataSource());
Path invoiceFilePath = storageService.getFilePath(FileCategoryEnum.INVOICE, orgId, invoiceFileName);
Resource resource = new UrlResource(invoiceFilePath.toUri());
if(resource.exists()) {
   resource.getFile().delete();
}
OutputStream outputStream = new FileOutputStream(invoiceFilePath.toFile());
JasperExportManager.exportReportToPdfStream(jasperPrint, outputStream);
outputStream.flush();
outputStream.close();

Any help is much appreciated.任何帮助深表感谢。

The subreport has no data source and doesn't generate any output (by default).子报表没有数据源并且不生成任何输出（默认情况下）。

There are (at least) two things that you can do.您可以（至少）做两件事。

  1. Pass a JREmptyDataSource to the subreport (like you do for the master report in your Java code):将JREmptyDataSource传递给子报表（就像您在 Java 代码中为主报表所做的那样）：

     <subreport isUsingCache="false"> <reportElement x="0" y="0" width="200" height="54" uuid="0b04fdb2-f4bb-4db2-935a-be96d92fa8db"/> <subreportParameter name="billingAddress"> <subreportParameterExpression><![CDATA[$P{billingAddress}]]></subreportParameterExpression> </subreportParameter> <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.JREmptyDataSource()]]></dataSourceExpression> <subreportExpression><![CDATA[$P{filePath} + "/BillingVenueSubReport.jasper"]]></subreportExpression> </subreport>

  2. Set whenNoDataType="AllSectionsNoDetail" in the subreport (at the <jasperReport> level).在子报表中设置whenNoDataType="AllSectionsNoDetail" （在<jasperReport>级别）。 That will result in the subreport printing all bands except the detail band when it has no data (which would do in your case because your subreport only uses the title band).这将导致子报表在没有数据时打印除详细信息波段之外的所有波段（在您的情况下会这样做，因为您的子报表仅使用标题波段）。
