Question

我想在数据集中设置参数值，实际值是在主报表参数字段中设置但不填充数据集参数，因为两者都是同名。即使在默认值选项中也没有显示设置主报表参数我正在使用ireport 4.0.2。你能告诉我如何动态设置数据集中的参数值，我正在通过HashMap。

提前感谢您的帮助。

            JasperReport report = JasperCompileManager.compileReport(design);
            JasperPrint print = JasperFillManager.fillReport(report,map, con);

            OutputStream pdfOP = new FileOutputStream(new File(
                    "/home/user/Desktop/OfferLetter.pdf"));

            JasperExportManager.exportReportToPdfStream(print, pdfOP);
            pdfOP.close();
            con.close();

我得到了答案，希望能帮到某个人。

我更改了列表数据源配置并映射了数据集的主报表参数。

  Right Click on List(component) -> Edit list(Component) -> Data source -> use connection expression -->Add parameter and map with default value of main report.

设置动态值数据集参数/ Mainreport参数-IREPORT的默认值
