I have used RateLimiterFilter in my Spring Cloud Gateway for implementing rate limiting
```java package com.lti.api.gateway.filter.pre; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.cloud.gateway.filter.ratelimit.KeyResolver; import org.springframework.stereotype.Component; import org.springframework.web.server.ServerWebExchange; import reactor.core.publisher.Mono; @Component public class RateLimiterFilter implements KeyResolver{ private static final Logger logger = LoggerFactory.getLogger(RateLimiterFilter.class); @Override public MonoExpected behavior/code
