为什么Redis密钥没有到期？

我已经检查了这些问题

但他们没有帮助我解决我的问题 . 我使用Spring-data-redis库在我的Spring REST应用程序中使用Redis作为速率限制的键值存储 . 我测试了巨大的负载 . 在那里我使用以下代码存储密钥，我也设置过期时间 . 大多数情况下密钥按预期到期 . 但有时关键还没到期！

代码段

RedisAtomicInteger counter = counter = new RedisAtomicInteger("mykey");
counter.expire(1, TimeUnit.MINUTES);

我使用redis-cli工具检查了密钥的可用性

键*

和

ttl keyname

redis.conf具有默认值 .

有什么建议 ？

完整代码：

该功能在Aspect中

public synchronized Object checkLimit(ProceedingJoinPoint joinPoint) throws Exception, Throwable {

        boolean isKeyAvailable = false;
        List<String> keysList = new ArrayList<>();

        Object[] obj = joinPoint.getArgs();
        String randomKey = (String) obj[1];
        int randomLimit = (Integer) obj[2];

        // for RedisTemplate it is already loaded as 

        // @Autowired
        // private RedisTemplate template; 

        // in this class
        Set<String> redisKeys = template.keys(randomKey+"_"randomLimit+"*");
        Iterator<String> it = redisKeys.iterator();
        while (it.hasNext()) {
               String data = it.next();
               keysList.add(data);
        }

        if (keysList.size() > 0) {
            isKeyAvailable = keysList.get(0).contains(randomKey + "_" + randomLimit);
        }

        RedisAtomicInteger counter = null;
        // if the key is not there
        if (!isKeyAvailable) {
              long expiryTimeStamp = 0;
              int timePeriodInMintes = 1;
              expiryTimeStamp = new Date(System.currentTimeMillis() + timePeriodInMintes * 60 * 1000).getTime();
              counter = new RedisAtomicInteger(randomKey+ "_"+ randomLimit + "_" + expiryTimeStamp,template.getConnectionFactory());
              counter.incrementAndGet();
              counter.expire(timePeriodInMintes, TimeUnit.MINUTES);
              break;

        } else {

              String[] keys = keysList.get(0).split("_");
              String rLimit = keys[1];

              counter = new RedisAtomicInteger(keysList.get(0), template.getConnectionFactory());
              int count = counter.get();
              // If count exceeds throw error
              if (count != 0 && count >= Integer.parseInt(rLimit)) {
                    throw new Exception("Error");
               }  
               else {
                    counter.incrementAndGet();
              }
      }
        return joinPoint.proceed();
    }

当这些线路运行时

RedisAtomicInteger counter = counter = new RedisAtomicInteger（“mykey”）; counter.expire（1，TimeUnit.MINUTES）;

在Redis日志中，当我“监视”它时
