hello, @vladimir-bukhtoyarov I found that I set a bucket with a capacity of 1 and a replenishment speed of 5 seconds plus 1 token on redis. Let's call it bucket 1 for now, but I want to change it to a bucket with a capacity of 5 and replenish 5 tokens in 5 seconds. For the time being Call it Bucket 2. I need to delete bucket 1 in redis by myself, and bucket 2 can be implemented.
Relative newcomer to bucket4j so pardon if there is an obvious answer to the question that I can't see.

//bucket1
String key = "127.0.0.1";
    //Capacity is 1, replenishment speed is 5 seconds each
    Bandwidth bandwidth = Bandwidth.classic(2, Refill.intervally(1, Duration.ofSeconds(5)));
    BucketConfiguration build = BucketConfiguration.builder().addLimit(bandwidth).build();
    RedisURI redisURI = RedisURI.create("127.0.0.1", 6379);
    RedisClient redisClient = RedisClient.create(redisURI);
    ProxyManager proxyManager =
            LettuceBasedProxyManager.builderFor(redisClient)
                    .withExpirationStrategy(ExpirationAfterWriteStrategy.none())
                    .build();
    Bucket bucket = proxyManager.builder().build(key, build);
    bucket.tryConsume(1);

// bucket2
 String key = "127.0.0.1";
    //The capacity is 5 and the replenishment speed is 5 seconds each
    Bandwidth bandwidth = Bandwidth.classic(5, Refill.intervally(5, Duration.ofSeconds(5)));
    BucketConfiguration build = BucketConfiguration.builder().addLimit(bandwidth).build();
    RedisURI redisURI = RedisURI.create("127.0.0.1", 6379);
    RedisClient redisClient = RedisClient.create(redisURI);
    ProxyManager proxyManager =
            LettuceBasedProxyManager.builderFor(redisClient)
                    .withExpirationStrategy(ExpirationAfterWriteStrategy.none())
                    .build();
    Bucket bucket = proxyManager.builder().build(key, build);
    bucket.tryConsume(1);
