java如何设置和删除cookie

Answer 1

/** * 删除cookie */ public static void clearCookie(HttpServletRequest request,HttpServletResponse response, String path) { Cookie[] cookies = request.getCookies(); try{ for(int i=0;i<cookies.length;i++) { //System.out.println(cookies[i].getName() + ”:” + cookies[i].getValue()); Cookie cookie = new Cookie(cookies[i].getName(), null); cookie.setMaxAge(0); cookie.setPath(path);//根据你创建cookie的路径进行填写 response.addCookie(cookie); } }catch(Exception ex) { System.out.println(“删除Cookies发生异常！”); } } public static void setCookie(HttpServletResponse response, String name, String value, String path) { if (logger.isDebugEnabled()) { logger.debug(“Setting cookie ’” + name + “‘ on path ’” + path + “‘”); } Cookie cookie = new Cookie(name, value); cookie.setSecure(false); cookie.setPath(path); cookie.setMaxAge(Constants.COOKIE_INVALID_TIME); response.addCookie(cookie); // logger.info(”setCookie 完成…….”); } //调用 String cookiename = “vbo”; String cookievalue = “cb”; String path = “/”; setCookie(response, cookiename , cookievalue , path); clearCookie(request,response,path);//如果有name的话，方法也要增加name过去才能匹配
