那些遇到过的问题

在iReport中有许多单独的 - 未完成的数据集

use*_*520 4 java jasper-reports subreport ireport

我正在使用iReport 2.0.4将一些数据从java应用程序导出到excel.

我的问题是我的子报告在顶级报告下进行分组,但我希望它们是离散报告.目前它看起来像这样

订单 - 订单
   行1
    收据 - 收据
       行1 -
       收据行2
    发票 - 发票
       行1 -
       发票行2
订单 - 订单
   行2
    收据 -
       收到行1
       ........

我希望它在一个电子表格中成为3个单独的报告.像这样

订购
    所有订单行
收货
    所有收货行
发票
    所有发票行

目前,我将订单作为主报告,收据和发票作为子报告,放入详细信息带订单.

如果可能的话,获得此布局的最佳方式是什么？

You can fill and compile three separate reports and then use JRPdfExporterParameter.JASPER_PRINT_LIST parameter for building the single report using code like this:

JasperReport ordersReport = JasperCompileManager.compileReport(srcOrdersReport);
JasperPrint jpOrdersReport = JasperFillManager.fillReport(ordersReport, ordersParamsMap, ordersDataSource);

JasperReport receiptsReport = JasperCompileManager.compileReport(srcReceiptsReport);
JasperPrint jpReceiptsReport = JasperFillManager.fillReport(receiptsReport, receiptsParamsMap, receiptsDataSource);

JasperReport invoicesReport = JasperCompileManager.compileReport(srcInvoicesReport);
JasperPrint jpInvoicesReport = JasperFillManager.fillReport(invoicesReport, invoicesParamsMap, invoicesDataSource);

List<JasperPrint> printList = new ArrayList<JasperPrint>();

printList.add(jpOrdersReport);
printList.add(receiptsReport);
printList.add(invoicesReport);

JRExporter exporter = new JRPdfExporter();
exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT_LIST, printList);

exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM, output);
exporter.exportReport();

You can look at this sample for your JR version - 2.0.4 for more details.

  • Second way. Using several datasets and list components

You can add several datasets in iReport 4.x version to the single report. Every dataset may contain its own query. The list component can use its own dataset.

In this sample (build with iReport 4.5.1) I've placed 3 list components to the Title band:
