  Commit · Pull request

  Adds the default limit of maximum file part count for upload (10000) and also gives an opportunity to override it and other two limits (upload maximum file size and maximum request size) by creating a custom StreamRequestHandler :

  public class CustomServiceInitListener implements VaadinServiceInitListener {
      @Override
      public void serviceInit(ServiceInitEvent event) {
          event.addRequestHandler(new CustomStreamRequestHandler());
      }
  
      private static final class CustomStreamRequestHandler
              extends StreamRequestHandler {
          // override getFileSizeMax() and/or getRequestSizeMax() if needed
          @Override
          protected long getFileCountMax() {
              // your limit:
              return 1000;
          }
      }
  }
