【问题描述】：

任何人都可以举一个简单的例子来调用一个jasper报告，其中子报告在一个java程序的子报告中。像这样（Generate Jasper report with subreport from java）：

JasperReport jasperMasterReport = JasperCompileManager.compileReport(masterReportSource);
JasperReport jasperSubReport1 = JasperCompileManager.compileReport(subReportSource1);
JasperReport jasperSubReport2 = JasperCompileManager.compileReport(subReportSource2);

Map<String, Object> parameters2 = new HashMap()<String, Object>;
parameters2.put("subreportParameter2", jasperSubReport2);

Map<String, Object> parameters1 = new HashMap()<String, Object>;
parameters1.put("subreportParameter1", JasperFillManager.fillReportToFile(jasperSubReport1, parameters2, connection));

JasperFillManager.fillReportToFile(jasperMasterReport, parameters1, connection);

谢谢。

    【解决方案1】：

    您可以将子报表路径作为主报表参数传递，并像这样获取子报表的数量。 

                String file = /pathToMainReport/name.jrxml;
            String subreport1 = /pathToSubReport/name1.jasper;
            String subreport2 = /pathToSubReport/name2.jasper;      

            JasperReport jreport = JasperCompileManager.compileReport(file);


            Map<String, Object> map = new HashMap<String, Object>();

            map.put("SUBREPORT_DIR1", subreport1);
            map.put("SUBREPORT_DIR2", subreport2);

            JasperPrint jprint = JasperFillManager.fillReport(jreport, map, connection);

    • 感谢 pariad neupane 的回答，但我想你给我看例子，主报告中的两个子报告：（（MasterReport Subreport1）和（MasterReport Subreport2）），但是我的问题很困难：（MasterReport Subreport1 Subreport2）。
    • 好吧，看看这个博客。 hamroblog-sristi.blogspot.com/2011/04/…
    • 谢谢，我会努力的。
    • 是的，hamroblog-sristi.blogspot.com/2011/04/... 它可以工作，但我确实想要使用参数调用报告的示例 java 代码 （用于 MasterReport）和 （用于 Subreport1）。
