spring boot項目之登出刪除緩存session至redis和cookies

一、從request中讀出cookies集合，然后封裝成map，為的是能夠直接通過name得到相應的cookie即get方法

public static Cookie get(HttpServletRequest request,
                         String name) {
    Map<String, Cookie> cookieMap = readCookieMap(request);
    if (cookieMap.containsKey(name)) {
        return cookieMap.get(name);
    }else {
        return null;
    }
}

/**
 * 將cookie封裝成Map
 * @param request
 * @return
 */
private static Map<String, Cookie> readCookieMap(HttpServletRequest request) {
    Map<String, Cookie> cookieMap = new HashMap<>();
    Cookie[] cookies = request.getCookies();
    if (cookies != null) {
        for (Cookie cookie: cookies) {
            cookieMap.put(cookie.getName(), cookie);
        }
    }
    return cookieMap;
}

二、在SellUserController類中的logout方法中調用CookieUtil.get()讀取cookie

然后清除redis和cookie
