连接到重定向ftp的Apache camel

我有以下简单的camel程序试图轮询ftp服务器上的文件

public class GetFilesFromFtp {

  public static void main(String[] args) throws Exception{
    CamelContext context = new DefaultCamelContext();
    context.addRoutes(new RouteBuilder() {

        public void configure() {
            from("ftp://<USER>@f<FTPHOST>/<FOLDER>?password=<PASSWORD>&passiveMode=true")
                .to("file:data/outbox");
        }
    });
    context.start();
    Thread.sleep(10000);
    context.stop();

  }

}

有人有什么想法吗？

尝试在ftp端点上设置

stepWise=false
