In reply to Aylin. In that case you need to define key-resolver bean.

In reply to Prateek.

Because there is no account-service. It is mocked. Here’s the full code: https://github.com/piomin/sample-spring-cloud-gateway/blob/master/src/test/java/pl/piomin/services/gateway/GatewayRateLimiterTest.java

Hi,
Could you share a link to other resources, it expects Account-service to be up, I dont see its code

io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: localhost/0:0:0:0:0:0:0:1:8091

Does it will save rate limit as key in redis ?

In reply to Sagar Gaikwad.

You can always create a RouteLocator bean and do it as visible below:
@Bean public RouteLocator routes(RouteLocatorBuilder builder) { return builder.routes()... }

How to set rate limit programmatically and not through properties?

First of all thanks for this great tutorial, Piotr!
I have a question, can we increase replenishRate to be per 10 seconds or per minute or more based on the route? Or generally increase this rate?
I tried to search a little bit and found that there is a redis lua script inside spring cloud gateway source code but I don’t know lua and I am not sure that would be the way to go to edit the window of replenishRate.

I tried integrating it with my project, but i am getting this error
java.lang.IllegalArgumentException: Unable to find GatewayFilterFactory with name RequestRateLimiter

Kind help if I am missing any thing.
