You need to develop a Spring Boot controller that can handle requests asynchronously, allowing for better scalability. How would you implement this feature in your controller?

To make a Spring Boot controller handle requests asynchronously for better scalability, you can use the @Async annotation on controller methods. This enables asynchronous processing of requests without blocking the main thread. Configuring a separate thread pool may be necessary for fine-tuning, but it's not the primary way to enable asynchronous handling in a controller. Using a different web framework is not required, as Spring Boot has built-in support for asynchronous operations. @Transactional is used for database transactions and is unrelated to request handling.
