从子报表生成PDF

我想从 Java 代码

生成pdf

String jrxmlFileLocation = "D:\\OrderSet.jrxml";
String jasperFileLocation = "D:\\OrderSet.jasper";
String outputPDFFile = "D:\\VisitsSummaryReport.pdf";
JasperCompileManager.compileReportToFile(jrxmlFileLocation, jasperFileLocation);
JasperCompileManager.compileReportToFile("D:\\Final_PatinetConsultation.jrxml", "D:\\Final_PatinetConsultation.jasper");

它已成功编译以及如何从此报告生成pdf文件，请在此代码中帮助我。

我看到这个链接但不明白 enter link description here

我使用像这样的结果集

String condition = "data = "+data;
PreparedStatement psOrderSet = conn.prepareCall("{call Sp_tbPatientOrderSet_GetAll(?)}",ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
psOrderSet.setString(1,condition);
ResultSet rsOrderSet = psOrderSet.executeQuery();
rsOrderSet.last();
int lengthOrderSet=rsOrderSet.getRow();
rsOrderSet.beforeFirst();

如何将ResultSet传递给子报表以填充数据。

Answer 1

使用JasperReport类型添加到主报告参数中的参数：

<parameter name="OrderSet" class="net.sf.jasperreports.engine.JasperReport" isForPrompting="false"/>

在主报表中 - 在subreportExpression中指向OrderSet参数

<subreport>

    <reportElement  x="-66" y="0" width="582" height="39"/>
    <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
    <subreportExpression><![CDATA[$P{OrderSet}]]></subreportExpression>

</subreport>

然后汇编和pdf导出：

String jrxmlFileLocation = "D:\\OrderSet.jrxml";
String outputPDFFile = "D:\\VisitsSummaryReport.pdf";

// Compile your main report
JasperReport jasperReport = JasperCompileManager.compileReport(
      "D:\\Final_PatinetConsultation.jrxml");
// Compile your subReport report
JasperReport jasperSubReport = JasperCompileManager.compileReport(
      jrxmlFileLocation);
//Initialize parameters
Map parameters = new HashMap();
//Add subreport as parameter for main report
parameters.put("OrderSet", jasperSubReport); 
// Convert to JasperPrint - you may fill parameters here also if any
// and provide java.sql.Connection
JasperPrint document = JasperFillManager.fillReport(jasperReport, parameters, connection);
// Export to pdf 
JasperExportManager.exportReportToPdfFile(document, outputPdfFile);

这应该适合你。
