Have PDF's in [jcr:data].
Am trying to zip the pdf files on a node and the response using spring blossom
controllers.
Following is the code for doing this
@RequestMapping(path = "/zip", params = {"do=zip" }, method =
RequestMethod.POST, produces = "application/zip")
public void download(HttpServletRequest request, HttpServletResponse response,
Node content){
response.getWriter().write(zipFiles())
}
public static byte[] zipFiles(String... uuids){
// creating byteArray stream, make it buffurable and passing
this buffur to ZipOutputStream
ByteArrayOutputStream baos = new ByteArrayOutputStream();
BufferedOutputStream bos = new BufferedOutputStream(baos);
ZipArchiveOutputStream zaos = new ZipArchiveOutputStream(bos);
try {
for (String uuid : uuids) {
Node fileNode =
NodeUtil.getNodeByIdentifier(ApplicationFunctions.LITERATURE_WORKSPACE, uuid);
Binary binary =
fileNode.getProperty("jcr:data").getBinary();
InputStream is = binary.getStream();
ZipArchiveEntry entry = new
ZipArchiveEntry(fileNode.getProperty("fileName").getString());
entry.setSize(fileNode.getProperty("size").getLong());
zaos.putArchiveEntry(entry);
zaos.write(IOUtils.toByteArray(is));
zaos.closeArchiveEntry();
}
} catch (Exception e) {
EtechLogger.error(FileUtil.class, "Exception in
zipFiles: " + e.getMessage());
} finally {
if (zaos != null) {
zaos.finish();
zaos.flush();
IOUtils.closeQuietly(zaos);
}
IOUtils.closeQuietly(bos);
IOUtils.closeQuietly(baos);
}
return baos.toByteArray();
}
