Question

我们正在尝试使用spring-boot（2.0.5.RELEASE）和redis实现RateLimiter。但是我们没有收到预期的响应，即httpStatusCode 429（请求过多）错误。我们看到应用程序已连接到Redis服务器。但我们没有在Redis服务器中看到密钥。我们没有任何错误。任何想法或任何可行的示例都将有所帮助。

请在下面找到pom.xml。

    }

    @Bean
    RedisRateLimiter myRateLimiter() {
        return new RedisRateLimiter(10, 20);
    }

带有Spring-boot 2.0.5.RELEASE的Redis RateLimiter
