Efficient web apps with spring boot 2

on YouTube ↗59m

" summary

A Spring Boot MVC dashboard app that calls three backend services gets converted to nonblocking calls: replaced RestTemplate with WebClient, composed responses with Reactor (map/flatMap/zip and timeout operators) to cancel slow remote calls, and exposed Micrometer metrics with a Prometheus registry and a dashboard to track capacity. A noisy reverse-lookup service showing ~7.7s max latency gets bounded by a 500ms–1500ms timeout in the demo, improving tail latency and preventing thread exhaustion.
