How to implement the Redis Rate Limiting in spring cloud gateway?

Question

I am trying to set up the rate-limiting in a spring cloud gateway.

I tried to configure the filter in the application.yaml as below

filters:
    - name: RequestRateLimiter
      args:
         redis-rate-limiter.replenishRate: 1
         redis-rate-limiter.burstCapacity: 5

I am getting the below error

java.lang.IllegalArgumentException: Unable to find GatewayFilterFactory with name RequestRateLimiter

How to implement the rate limit in the spring cloud gateway?

Answer 1

One of the possibilities is not including the following dependency (the mistake which I did first time)

org.springframework.boot:spring-boot-starter-data-redis-reactive

Since the args contain redis-rate-limiter this dependency is must.

Below is a screenshot from the IDE showing RequestRateLimiterGatewayFilterFactory getting added when the above dependency is included.
