Cookies 在restlet中设置cookie

我在restlet中设置cookie的时间非常之长，以下是我目前所做的：

public class CookieTestResource extends ServerResource {

    @Post
    public Representation post(Representation representation){
        CookieSetting cS = new CookieSetting(
                1, 
                "cookieName", 
                "cookieValue"
                );
        Series<CookieSetting> cookies = new Series<CookieSetting>(); //<--PROBLEM
        cookies.add(cS);
        this.setCookieSettings(cookies);
        // SEND RESPONSE
        setStatus(Status.SUCCESS_OK);
        return new StringRepresentation("");
    }
}

公共类CookieTestResource扩展了ServerResource{
@职位
公众代表职位（代表）{
CookieSetting cS=新CookieSetting(
1.
“cookieName”，
“cookieValue”
);
Series cookies=new Series（）；//答案如下：

（我在'this.getResponse（）.getCookieSettings（）.add（cS）；'中缺少'getResponse（）'）

public class CookieTestResource extends ServerResource {

    @Post
    public Representation post(Representation representation){

        CookieSetting cS = new CookieSetting(0, "cookieName", "cookieValue");
        this.getResponse().getCookieSettings().add(cS);

        // SEND RESPONSE
        setStatus(Status.SUCCESS_OK);
        return new StringRepresentation("");
    }
}
