Yes, it is technically possible to use both Spring Web MVC and Spring WebFlux in the same application, but it comes with certain considerations and limitations.
Spring Web MVC and Spring WebFlux can coexist within the same application framework, allowing developers to utilize the strengths of both synchronous and asynchronous processing models depending on the specific requirements of different parts of the application. This can be particularly useful in scenarios where parts of your application might benefit from the reactive programming model provided by WebFlux, while other parts might continue using the traditional, synchronous Spring MVC model.
However, integrating both frameworks in a single application requires careful configuration to avoid conflicts and ensure efficient operation. For instance, if both MVC and WebFlux are available in the classpath, Spring Boot will auto-configure a Spring MVC application by default[3]. This means that specific configurations are needed to enable WebFlux alongside MVC.
Moreover, using both frameworks together does not mean that they can share the same controllers or routing configurations seamlessly. Each framework has its own distinct mechanisms for handling requests and responses. For example, Spring MVC uses a servlet-based architecture, whereas WebFlux employs a non-blocking, reactive programming model[2]. This fundamental difference implies that you cannot simply switch from one to the other wit...
