Async Controllers with Spring Boot by Mihaita Tinta Medium, Note that existing ExceptionHandlers used for errors happening before the controller method is invoked are still valid because Spring won t deal with the actual async return type for example
Getting Started Creating Asynchronous Methods Spring
For example if spring webmvc is on the classpath this annotation flags the application as a web application and activates key behaviors such as setting up a DispatcherServlet ComponentScan Tells Spring to look for other components configurations and services in the com example package letting it find the controllers
