Springboot + zset + lua 实现滑动窗口

@Component
public class RedisRateLimiter {@Autowiredprivate RedisTemplate<String, String> redisTemplate;private String luaScript() {return "redis.call('zremrangebyscore', KEYS[1], 0, tonumber(ARGV[1]) - tonumber(ARGV[2]) * 1000) " + // 移除过期的元素"if tonumber(redis.call('zcard',KEYS[1])) < tonumber(ARGV[3]) then " +  // 获取当前窗口内的元素数量，如果当前窗口内的元素数据超过窗口大小，删除最旧的元素, 窗口内的元素数量小于窗口大小"redis.call('zadd', KEYS[1], tonumber(ARGV[1]), tonumber(ARGV[1])) " + // 将新元素添加到ZSET中"redis.call('expire', KEYS[1], tonumber(ARGV[2])) " + // 设置过期时间"return true " +"else " +"return false " +"end";}public boolean slideWindowAlgorithmByLua(String key, int limitCount, long windowTime) {long currentTime = System.currentTimeMillis();List<String> argList = new ArrayList<>();argList.add(String.valueOf(currentTime));argList.add(String.valueOf(windowTime));argList.add(String.valueOf(limitCount));RedisScript<Boolean> redisScript = new DefaultRedisScript<>(this.luaScript(), Boolean.class);return Boolean.TRUE.equals(redisTemplate.execute(redisScript, Collections.singletonList(key), argList.toArray()));}}

亲测有效，有何问题，请批评指正！
