使用redisTemple 设置setnx，同时设置失效时间

public boolean setNx(String key, String value, Integer time) {

    //Object obj = null;
    Boolean obj = false;
    try {
        /* redis
        obj = redisTemplate.execute(new RedisCallback<Object>() {
            @Override
            public Object doInRedis(RedisConnection connection) throws DataAccessException {
                StringRedisSerializer serializer = new StringRedisSerializer();
                Boolean success = connection.setNX(serializer.serialize(key), serializer.serialize(value));
                redisTemplate.expire(key, time, TimeUnit.SECONDS);

                connection.close();
                return success;
            }
        });*/

        //spring-data-redis 包升级到 2.1.x 版本以上
        obj = redisTemplate.opsForValue().setIfAbsent(key, value, time, TimeUnit.SECONDS);

    } catch (Exception e) {
        log.error("setNX redis error, key : {}" + key, e);
    }

    return obj;
}
