用 Java

要匯出，你需要填寫報告以獲取 JasperPrint物件。

將單個 JasperPrint（單個 jrxml）匯出到檔案

// 1. Create exporter instance
JRPdfExporter exporter = new JRPdfExporter();

// 2. Set exporter input document
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));

// 3. Set file path for exporter output
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput("/path/filename.pdf"));

// 4. Create configuration instance
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();

// 5. Associate configuration with exporter
exporter.setConfiguration(configuration);

// 6. Fill export and write to file path
exporter.exportReport();

將多個 JasperPrint（多個 jrxml）匯出到單個檔案

只有第一步與前一組不同：

List<JasperPrint> jasperPrintList = new ArrayList<>();
jasperPrintList.add(jasperPrint1);
jasperPrintList.add(jasperPrint2);

JRPdfExporter exporter = new JRPdfExporter();
exporter.setExporterInput(SimpleExporterInput.getInstance(jasperPrintList));

其餘步驟相同：

exporter.setExporterOutput(new SimpleOutputStreamExporterOutput("/path/filename.pdf"));
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
exporter.setConfiguration(configuration);
exporter.exportReport();
