   可以使用invocation这个参数进行传递.
   在过滤器的afterReceiveRequest()方法中,将你要传递的header参数使用
   invocation.addContext(Constants.DEVELOPER_UID, “123456”);
   的方式进行包装，然后在Controller中使用
   public Response logout(InvocationContext context) {
           String value = context.getContext(Constants.DEVELOPER_UID);
           return null;
       }
   即可获取到值。
