Here the simple route:
public class InputHttpRoute extends RouteBuilder { @Override public void configure() throws Exception { from(http()) .noStreamCaching() .process(e -> { e.getIn(AttachmentMessage.class).getAttachments() .forEach((s, dataHandler) -> { InputStream files = null; try { files = dataHandler.getInputStream(); byte[] buffer = new byte[10500]; int b; while ((b = files.read(buffer)) != -1) { // Convert byte to character String data = new String(buffer, 0, b); System.err.println(data); } } catch (IOException ex) { throw new RuntimeException(ex); } });; } private static String http() { return new StringBuilder("jetty:http://0.0.0.0:8787/myservice") .append("?httpMethodRestrict=") .append("POST") .toString(); } }// espace réservé du code
The file is fully loaded in memory before i can access it this is a unwanted behavior and it will be nice if it will be possible to start processing the file during the upload in streaming fashion mode
