Spring Tips: Spring Cloud Gateway

Speaker: Josh Long
Hi Spring fans! In this installment of Spring Tips we’ll look at the new API gateway project, Spring Cloud Gateway, to support edge service requirements like rate limiting, circuit breakers, proxying, and more.

Josh Long is a God!

[@benm1295]

Maybe the best and most comprehensive Spring Cloud Tutorial so far! Great.

[@cloud4java]

Great and comprehensive video about API Gateway. Really an amazing tool!

[@aakoss]

Great presentation as always from Josh.

[@Yangslehollandais]

Very Good Tuto

[@stealthmusic1]

Would you always use that for a specific application? Or is there a way to use that as a generic gateway by providing some kind of configuration file that replaces the code that you did for the routing?

[@JustinHopperIsJuice]

I realize that Gateway is fresh off of the factory floor and this video is now 4 months old but is it me or did the fluent api for route builder change significantly. I tried to do something similar to the chain but did not find the appropriate methods. Thanks Josh

[@alexmalinovsky8278]

Do you have some sample repo for that?

[@brianthalhamer1971]

can routes be authorized, i.e. user needs to have a specific role like @Preauthorize on controller methods? I know you can define these as ant matches in the security configuration, but it would make the code easier to read/manage if it was here.

[@warsicdia2670]

What if Browser should contact a service through the gateway ? I am facing a Cross origin request. My question is: Where do I configure cross origin request access? in the gateway service or in the downstream service ? Please, help me.

[@KezyORoan]

Awesome guide. This cleared out most questions I have on getting started with Spring Cloud. I do have one very important question though which I haven't been able to find an answer for anywhere. I need to be able to setup routes on a database (sql or nosql) instead of withing java code or configuration file. Is this possible? What do I need to achieve this? Any help will be greatly appreciated.

[@mohantalachutla6834]

Never heard of it. Is there a thing like the in db world?

[@wangdavid4080]

Nice video! Could you share the uao command?

[@hemantbhoyar4462]

Great video but documentation seems to be missing for spring cloud gateway tough

[@WilberTorres]

The most amazing tool that I have ever seen, just one question, that rate limit is per set instances right ? , how it could be per microservice instance

[@JoshLong]

Hi - the rate limit is per authenticated principal. it creates a key (in this case, based on the authenticated user) and it says "josh can only make X requests to the service on which the rateLimiter has been applied." you can provide custom key resolvers that work for any distinct key that you want.

[@AbhijithVMohan]

I guess the question was whether the counters are in memory, and not shared across loadbalanced instances of the service. As per the current source code on github, it seems like the counters are shared across instances using redis.

[@KentOJohnson]

Well done. It is easy to translate this to Kotlin. If anyone wants a github link just ask.

[@KushagraSahni93]

Kindly share one please.

[@revatisonawane5468]

please give github link

[@arpandas8416]

Can we get the github links of these example projects.

[@GiliardLourenco]

Please, would you like to pass the girhub url if possible?

[@hatemjaber]

spring.io/blog/2017/12/05/spring-cloud-finchley-m5-released#spring-cloud-gateway Use the above link to replace the @Bean RouteLocator code if you're on a newer version of Spring Boot than what's used in the video.
