Question

我在我的java代码中添加了JRBeanCollectionDataSource，并在我的mainreport和subreport中添加了参数。但我无法在jrxml中打印参数。请告诉我我需要什么使用jrxml中的参数。

JAVA CODE：

      List<InvoiceDTO> invoiceList = new ArrayList<InvoiceDTO>();
      invoiceList.add(invoice);
      JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(invoiceList);
      JasperPrint report = null;
      parameters.put("invoiceList",invoiceList);
      report = JasperFillManager.fillReport(stream, parameters, new JREmptyDataSource());

在子报告中，我已经分配了参数，但它无法正常工作。

<textField>
            <reportElement x="164" y="3" width="75" height="14" />
            <textFieldExpression><![CDATA[$P{invoiceList}]]>    </textFieldExpression>
        </textField>

Answer 1

在主报告中将列表用作字段变量。

<field name="yourList" class="java.util.ArrayList">
        <fieldDescription><![CDATA[]]></fieldDescription>
</field>

，数据源表达式应为

<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{yourList}, false)]]></dataSourceExpression>
<subreportExpression><![CDATA[$P{SUBREPORT_DIR} + "ageing-esr-40-srpski-subreport1.jasper"]]></subreportExpression>

从控制器端，您应该通过列表

JasperReport jasperMasterReport = (JasperReport) JRLoader.loadObjectFromFile(your_jasper_file_path);    
JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(dataList, false);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperMasterReport, parameters, beanColDataSource);

假设你有InvoiceDTO类并且有一些成员

String name;
String email;

您只需

即可从子报表访问此内容

<field name="name" class="java.lang.String"/>
<textFieldExpression><![CDATA[$F{name}]]></textFieldExpression>

希望这会有所帮助。

如何在jrxml中使用java.util.Collection参数？
