任何人都可以举一个简单的例子来调用java子程序中子报表中子报表的jasper报表。这样的事情(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);
MasterReport.jrxml

感谢。

您可以将子报表路径作为主报表参数传递,并获取此类子报表的数量。
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);
