在spring data reactive Redis模板中没有用于限制流大小的maxlen选项

import org.springframework.data.redis.core.ReactiveRedisTemplate;
import org.springframework.data.redis.core.script.RedisScript;
import reactor.core.publisher.Mono;

public class RedisListSizeLimitExample {

    private ReactiveRedisTemplate<String, String> redisTemplate;
    private RedisScript<String> ltrimScript;

    public RedisListSizeLimitExample(ReactiveRedisTemplate<String, String> redisTemplate, RedisScript<String> ltrimScript) {
        this.redisTemplate = redisTemplate;
        this.ltrimScript = ltrimScript;
    }

    public Mono<Long> addToList(String key, String value, int maxSize) {
        return redisTemplate.opsForList().leftPush(key, value)
                .flatMap(size -> {
                    if (size > maxSize) {
                        return redisTemplate.execute(ltrimScript, key, "0", String.valueOf(maxSize - 1))
                                .thenReturn(maxSize);
                    } else {
                        return Mono.just(size);
                    }
                });
    }
}
