Codice servlet

Di seguito è riportato lo snippet di codice del servlet. Il codice estrae il modello (xdp) e il file di dati (xml) dalla richiesta. Il file modello viene salvato nel file system. Vengono create due mappe: templateMap e dataFileMap che contengono rispettivamente il modello e i file xml(data). Viene quindi effettuata una chiamata al metodo generateMultipleRecords del servizio DocumentServices.

for (final java.util.Map.Entry < String, org.apache.sling.api.request.RequestParameter[] > pairs: params
.entrySet()) {
final String key = pairs.getKey();
final org.apache.sling.api.request.RequestParameter[] pArr = pairs.getValue();
final org.apache.sling.api.request.RequestParameter param = pArr[0];
try {
if (!param.isFormField()) {

if (param.getFileName().endsWith("xdp")) {
    final InputStream xdpStream = param.getInputStream();
    com.adobe.aemfd.docmanager.Document xdpDocument = new com.adobe.aemfd.docmanager.Document(xdpStream);

    xdpDocument.copyToFile(new File(saveLocation + File.separator + "fromui.xdp"));
    templateMap.put("key1", "file://///" + saveLocation + File.separator + "fromui.xdp");
    System.out.println("####  " + param.getFileName());

}
if (param.getFileName().endsWith("xml")) {
    final InputStream xmlStream = param.getInputStream();
    com.adobe.aemfd.docmanager.Document xmlDocument = new com.adobe.aemfd.docmanager.Document(xmlStream);
    dataFileMap.put("key1", xmlDocument);
}
}

Document zippedDocument = documentServices.generateMultiplePdfs(templateMap, dataFileMap,saveLocation);

Codice di implementazione dell’interfaccia

Il codice seguente genera più file PDF utilizzando generatePDFOutputBatch di OutputService e restituisce un file zip contenente i file PDF al servlet chiamante

public Document generateMultiplePdfs(HashMap < String, String > templateMap, HashMap < String, Document > dataFileMap, String saveLocation) {
    log.debug("will save generated documents to " + saveLocation);
    com.adobe.fd.output.api.PDFOutputOptions pdfOptions = new com.adobe.fd.output.api.PDFOutputOptions();
    pdfOptions.setAcrobatVersion(com.adobe.fd.output.api.AcrobatVersion.Acrobat_11);
    com.adobe.fd.output.api.BatchOptions batchOptions = new com.adobe.fd.output.api.BatchOptions();
    batchOptions.setGenerateManyFiles(true);
    com.adobe.fd.output.api.BatchResult batchResult = null;
    try {
        batchResult = outputService.generatePDFOutputBatch(templateMap, dataFileMap, pdfOptions, batchOptions);
        FileOutputStream fos = new FileOutputStream(saveLocation + File.separator + "zippedfile.zip");
        ZipOutputStream zipOut = new ZipOutputStream(fos);
        FileInputStream fis = null;

        for (int i = 0; i < batchResult.getGeneratedDocs().size(); i++) {
              com.adobe.aemfd.docmanager.Document dataMergedDoc = batchResult.getGeneratedDocs().get(i);
            log.debug("Got document " + i);
            dataMergedDoc.copyToFile(new File(saveLocation + File.separator + i + ".pdf"));
            log.debug("saved file " + i);
            File fileToZip = new File(saveLocation + File.separator + i + ".pdf");
            fis = new FileInputStream(fileToZip);
            ZipEntry zipEntry = new ZipEntry(fileToZip.getName());
            zipOut.putNextEntry(zipEntry);
            byte[] bytes = new byte[1024];
            int length;
            while ((length = fis.read(bytes)) >= 0) {
                zipOut.write(bytes, 0, length);
            }
            fis.close();
        }
        zipOut.close();
        fos.close();
        Document zippedDocument = new Document(new File(saveLocation + File.separator + "zippedfile.zip"));
        log.debug("Got zipped file from file system");
        return zippedDocument;


    } catch (OutputServiceException | IOException e) {

        e.printStackTrace();
    }
    return null;
