在JSF PhaseListener中添加cookie [英] Adding cookie in JSF PhaseListener

问题描述

我有一个使用JSF 1.1版的旧版应用程序

I have a legacy application using JSF version 1.1

我试图在所有响应中设置cookie，但是要通过 PhaseListener code>的实现，而不是通常的 Filter ，因为有具体的要求。

I am trying to set a cookie in all responses, but through a PhaseListener implementation instead of usual Filter because of specific requirement.

我做了类似的事情：

public class MyPhaseListener implements PhaseListener {

    public PhaseId getPhaseId() {
        return PhaseId.ANY_PHASE;
    }

    public void beforePhase(PhaseEvent event) {
    }

    public void afterPhase(PhaseEvent event) {
        if (event.getPhaseId() == PhaseId.RENDER_RESPONSE) {
            HttpServletResponse httpResponse = (HttpServletResponse) FacesContext
                            .getCurrentInstance().getExternalContext().getResponse();
            int cookieValue = 100;
            Cookie cookie = new Cookie("myCookie", "" + cookieValue);
            cookie.setPath("/");
            httpResponse.addCookie(cookie);
        }
    }
}

但是，当我检查时在Chrome开发者控制台中的响应中，我看不到此Cookie。

However, when I am checking the responses in chrome dev console, I do not see this cookie.

我在做什么错了？

推荐答案

可能在RENDER_RESPONSE之后直到深夜，RENDER_RESPONSE才能正常工作。

after RENDER_RESPONSE is probably to late, before RENDER_RESPONSE should work fine.
