我可以使用Spring 5 WebFlux WebClient使用非反应式REST API服务吗？

Question

I have a written a microservice using Spring 5 WebFlux and trying to consume a non-reactive REST API through it. Is it possbile to consume a non-reactive service using a reactive webclient?

Answer 1

Yes, this is possible. From the server's point of view, this is just a regular HTTP client. WebClient does support streaming and backpressure, but this doesn't change things at the HTTP level.

The backpressure is dealt with at the TCP flow-control level, so the HTTP protocol stays the same.
