Is it possible to completely exclude the presence of a controller in this context?

In the context of Java, especially when developing web applications using Spring MVC or similar frameworks, the controller plays a key role in handling HTTP requests and routing. It is possible to completely eliminate the controller by using alternative approaches, such as reactive frameworks (Spring WebFlux) or serverless architectures, where request processing logic can be implemented in functions without an explicit controller.

However, in the traditional MVC approach, the controller is necessary for separating responsibilities and managing the data flow between the model and the view. Omitting the controller can lead to mixed logic and increased difficulty in maintaining the code.

Therefore, it is possible to completely eliminate the controller, but this depends on the architecture and technologies used.
