现在，如何使用子报告为Jasper报告编写带有XML数据源的Java代码？我试过这个：

JasperPrint print = new JasperPrint();
JRPdfExporter exporter = new JRPdfExporter();
JasperDesign design, design1;
JasperReport report, report1;
JasperReport jasperReport;
JasperDesign jd1;


jd1 = JRXmlLoader.load("C:/Users/bferrao/Desktop/jasper/TransactionReport_subreport1.jrxml");
jasperReport = JasperCompileManager.compileReport(jd1);

Map parameters = new HashMap();
parameters.put("Subreport_1", jasperReport);

design = JRXmlLoader.load("C:/Users/bferrao/Desktop/jasper/TransactionReport_subreport2.jrxml");
report = JasperCompileManager.compileReport(design);
parameters.put("Subreport_2", report);

Document document = JRXmlUtils.parse(new File("C:/Users/bferrao/Desktop/jasper/TransactionReport.xml"));
parameters.put(JRXPathQueryExecuterFactory.PARAMETER_XML_DATA_DOCUMENT, document);

JRXmlDataSource jrxmlds = new JRXmlDataSource(new File("C:/Users/bferrao/Desktop/jasper/TransactionReport.xml"), "/Report");
design1 = JRXmlLoader.load("C:/Users/bferrao/Desktop/jasper/TransactionReport.jrxml");
report1 = JasperCompileManager.compileReport(design1);
JasperFillManager.fillReportToFile(report1, "C:/Users/bferrao/Desktop/jasper/master_report.jrprint", parameters, jrxmlds);

exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "D:\\temp\\Report3.pdf");
exporter.exportReport();

查看您的stackoverflow我已经修改了我的主报告和java构建报告。如何传递XML数据源？我还在报告空白。

Answer 1

在Java代码中，您将两个subReport添加为参数Subreport_1和Subreport_2，但主报告仅声明一个名为“SUBREPORT_DIR”的参数。

我做了类似于Java代码的事情（总结）：

   // first compile the sub reports
   jasperReport = JasperCompileManager.compileReport(jd1);
   jasperReport = JasperCompileManager.compileReport(jd1);
   report = JasperCompileManager.compileReport(design);

   // then add the compiled reports to your parameters
   Map parameters = new HashMap();
   parameters.put("Subreport_1", jasperReport);
   parameters.put("Subreport_2", report);

   // and finally send the sub-reports to the main report as parameters
   JasperFillManager.fillReportToFile(report1, "D:/temp/master_report.jrprint", parameters, jrxmlds);

您必须在master jrxml：

中将子报表声明为此参数

<parameter name="Subreport_1" class="java.lang.Object"/>
<parameter name="Subreport_2" class="java.lang.Object"/>

...

<subreport runToBottom="false">
    <reportElement uuid="ce3bf2a2-9131-4d75-800b-25d4a71791c3" 
         positionType="Float"    isPrintRepeatedValues="false" 
         x="0" y="179" width="468" height="28" isRemoveLineWhenBlank="true"/>
    <subreportParameter name="XML_DATA_DOCUMENT">
        <subreportParameterExpression><![CDATA[$P{XML_DATA_DOCUMENT}]]></subreportParameterExpression>
    </subreportParameter>
    <subreportExpression><![CDATA[$P{Subreport_1}]]></subreportExpression>
</subreport>

并且可以删除以下参数，因为它似乎未在您的代码中使用：

<parameter name="SUBREPORT_DIR" class="java.lang.String" isForPrompting="false">
        <defaultValueExpression><![CDATA["C:\\Users\\bferrao\\Desktop\\jasper\\"]]></defaultValueExpression>
</parameter>

您必须要小心的另一件事是子报告中的数据源可见性。
