Spring Boot using RestController and ServletRegistrationBean in same application

Question

I have a Controller class annotated with @RestController containing @ReguestMapping annotations on the class' methods to identify the endpoints.

I need to add a SpeechletServlet (part of the Alexa-skill-kit) to receive requests at an endpoint /zebra-tape at the same time that the other endpoints are still available.

Using the code below I loose access to the endpoints annotated with @RequestMapping

public class Application extends SpringBootServletInitializer {

    @Bean
    public ServletRegistrationBean dispatcherServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(new ZebraTapeServlet());
        registration.addUrlMappings("/zebra-tape");
        return registration;
    }
}

How can I have access to both types of endpoints?

Answer 1

Rename your bean method to something other than dispatcherServletRegistration. That name is used by Spring Boot for the registration bean for the auto-configured dispatcher servlet. By declaring a bean method with the same name, you are switching that auto-configuration off.
