If so, how? and what are the consequences when we block the WebClient to get the result? And finally, what is the best configuration in this scenario?Yes, and the Spring team encourages us to do this. Suppose we add both spring-boot-starter-web and spring-boot-starter-webflux libraries dependencies in our build file. In that case, the Spring Boot auto-configuring will prioritize Spring MVC over WebFlux, allowing us to use WebClient in our Spring MVC project to make asynchronous HTTP requests to external services or APIs.WebClient is a non-blocking, reactive web client. It returns reactive data types from Project Reactor (Mono or Flux). When we use WebClient in a Spring Boot Web MVC project, we need to call the block() method from the Reactor data types (Mono or Flux). By calling the block() method, we block the current thread and retrieve data synchronously, but the WebClient performs an asynchronous, non-blocking call to the external service.
