springmvc session和cookie

写入session和cookie

  @PostMapping("/logon")
    public ReturnT<Object> logon(HttpServletRequest request, HttpServletResponse response) throws Exception {
        String name = request.getParameter("name");
        String passWord = request.getParameter("passWord");
        UserEntity user= userService.logon(name,passWord);
        request.getSession().setAttribute("id", user.getId());//设置session
        request.getSession().setAttribute("name", user.getName());//设置session

        Cookie cName = new Cookie("name", URLEncoder.encode(user.getName(), "utf-8"));
        Cookie cId = new Cookie("id", String.valueOf(user.getId()));
        cName.setPath("/");
        cId.setPath("/");
        response.addCookie(cName);
        response.addCookie(cId);
        return new ReturnT<>();
    }

使用session

    @PostMapping("/updatePass")
    public ReturnT<Object> updatePass(HttpServletRequest request) throws Exception {
        String passWord = request.getParameter("passWord");
        String name = request.getSession().getAttribute("name").toString();
        userService.updatePass(name,passWord);
        return new ReturnT<>();
    }
