java清除及设置cookie代码

 1,清除cookie代码示例：

/**
     * 清空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("清空Cookies发生异常！");
      } 
     
    }

 调用eg：clearCookie(request, response, "/");

 

2，设置cookie代码示例：

 /**
     * Convenience method to set a cookie
     * @param response
     * @param name
     * @param value
     * @param path
     */
    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eg：

String cookie_name = "222";
CookieUtil.setCookie(response, "cookie_name", cookie_name, "/");

您好，请问一下:
logger.isDebugEnabled
Constants.COOKIE_INVALID_TIME
logger(log4j我不太熟)和Constants ,这个应该是导入哪个包
