问题概述： 现在用支付宝即时到账业务，异步通知出现了问题：
apache 的 error message 是:
java.lang.IllegalArgumentException: The Content Type could not be read.

我已经试过加annotation:

 @Post("application/json")

或者加request headers:

 ClientResource cr = new ClientResource("...");
        Series<Header> headers = (Series<Header>)      cr.getRequestAttributes().get("org.restlet.http.headers");
     if (headers == null) {              
        headers = new Series(Header.class); 
        headers.add("Access-Control-Allow-Origin", "*");
        headers.add("Access-Control-Allow-Methods", "POST, GET, PUT, DELETE, OPTIONS");
        headers.add("Access-Control-Allow-Headers", "Content-Type");                
        headers.add("Access-Control-Allow-Headers", "authCode");
        headers.add("Access-Control-Allow-Headers", "origin, x-requested-with, content-type");
    } 

    if (headers != null) {              
        headers.add("Content-Type", "application/json");                
        cr.getRequestAttributes().put("org.restlet.http.headers", headers); 
    }

但是都没有解决问题，看起来支付宝发的异步post在进入post code handler 之前就因为restlet的content-type 问题挂掉了
求大神指点
