java实战生成token并放入redis设置过期时间

        String token = JWT.create().withHeader(header).withClaim("user", JSON.toJSONString(user)).withIssuedAt(iatDate)
                // .withExpiresAt(expiresDate)
                .sign(Algorithm.HMAC256(SECRET));

        try {
            StringRedisTemplate redis = ApplicationContextUtils.getBean(StringRedisTemplate.class);
            redis.opsForValue().set(Const.REDIS_TOKEN_PREFIX + token, user.getLoginName(), 240L, TimeUnit.MINUTES);
        } catch (Exception e) {
            throw new BusinessErrorException(ErrorMsg.TOKEN_REDIS_ERROR);
        }
        return token;
