JAVA时间比较

        Date data = new Date();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        String time = sdf.format(data);

        int res1 = branchStartTime.compareTo(time);
        int res2 = time.compareTo(branchEndTime);

        if (res1 > 0 || res2 > 0) {
            result.put("result", 0);
            result.put("message", "用户所属机构现在无权限登录");
            return result.toJSONString();
        }
