1.写入cookie
HttpServletResponse response = ServletUtils.getResponse(); // 将token设置到cookie 返回 Cookie cookie = new Cookie(Constants.HEADER_ACCESS_TOKEN_KEY, tokenVo.getToken()); cookie.setPath("/"); //设置cookie的有效时长为100天，默认关闭浏览器失效，单位为:秒 cookie.setMaxAge(100*24*60*60); response.addCookie(cookie);2.获取cookie
public class getCookie(HttpServletRequest request){ Cookie[] cookies = request.getCookies(); if (cookies == null || cookies.length <= 0) { response.setStatus(HttpServletResponse.SC_UNAUTHORIZED); throw new ServiceException(ErrorCode.authority_un_login.getCode(), ErrorCode.authority_un_login.getMessage()); } for (Cookie cookie : cookies) { if (Constants.HEADER_ACCESS_TOKEN_KEY.equals(cookie.getName())) { token = cookie.getValue(); } if (Constants.HEADER_COOKIE_FRANCHISEE_ID.equals(cookie.getName())) { franchiseeId = cookie.getValue(); } } }3.工具类
