获取自定义标头作为响应，轻松休息

Question

服务器

Class MyService{

    @Context
    private HttpServletResponse httpResponse;

    @POST
    @Consumes({"application/json"})
    @Produces({"application/json"})
    public String handlePostRequest(Object resource) {

    httpResponse.addHeader("X-Origin", resPrim.getFrom());
    httpResponse.addHeader("X-RI", resPrim.getRequestIdentifier());
    httpResponse.addHeader("X-RET", resPrim.getResultExpirationTimestamp());
    httpResponse.setStatus(getHttpStatusCode());

    return "DUMMY"; 

}

客户端：

HttpResponse httpResponse = httpclient.execute(httpUriRequest);

System.out.println("RESPONSE_STATUS_CODE: " + httpResponse.getStatusLine().getStatusCode());

    for (Header h: httpResponse.getAllHeaders()) {           
                    //Do your stuff here
                    System.out.println("HEADER" + h); 
    }

当我在客户端打印标题时，SOP显示：

HEADER Server: Apache-Coyote/1.1
HEADER Content-Type: application/json
HEADER Content-Length: 4
HEADER Date: Tue, 24 Nov 2015 08:33:53 GMT

我的回复标题是否未被添加？

我想获取我在服务器上设置的自定义标题，但响应只有上面的4个标题。

如何获取自定义标头？
