使用Struts 2和Struts的cookie

HttpServletResponse response = (HttpServletResponse) ActionContext.getContext().get(ServletActionContext.HTTP_RESPONSE);
Cookie cookie = new Cookie("name", "value");
response.addCookie(cookie);

HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);
Cookie[] cookies = request.getCookies();
if (cookies != null) {
    for (Cookie cookie : cookies) {
        if ("name".equals(cookie.getName())) {
            String value = cookie.getValue();
            // do something with the value
        }
    }
}

HttpServletResponse response = (HttpServletResponse) ActionContext.getContext().get(ServletActionContext.HTTP_RESPONSE);
HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);
Cookie[] cookies = request.getCookies();
if (cookies != null) {
    for (Cookie cookie : cookies) {
        if ("name".equals(cookie.getName())) {
            cookie.setMaxAge(0);
            response.addCookie(cookie);
        }
    }
}
