In modern distributed systems, calling other services from an application is a common task for developers. The use of WebClient is ideally suitable for such tasks owing to its non-blocking nature.
The WebClient is a reactive HTTP client in Spring WebFlux. Its main advantage is asynchronic, non-blocking communication between microservices or external APIs. Everything in WebClient is built around events and reactive streams of data, enabling you to focus on business logic and forget about efficient management of threads, locks, or state.
