Asynchronous Programming with Kotlin Coroutines in Spring

on YouTube ↗44m

" summary

Shows how Kotlin 1.1 coroutines plug into Spring using the spring-kotlin-coroutine library by implementing a MethodArgumentResolver for Continuation and an AsyncHandlerMethodReturnValueHandler that maps coroutines to Spring DeferredResult, then running a live demo that converts a blocking app to suspending endpoints. Demonstrates custom CoroutineContexts (an external-service context thread pool), switching to WebClient/WebFlux + Netty, reactive Mongo repositories, suspending event listeners, and confirms the examples run end-to-end.
