Overriding Handler Mapping via WebMvcRegistrations

By implementing WebMvcRegistrations, you can provide your own RequestMappingHandlerMapping, allowing you to intercept how Spring MVC maps URLs to controller methods at a fundamental level.

java

@Configuration
public class CustomWebRegistrations implements WebMvcRegistrations {
    @Override
    public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
        return new RequestMappingHandlerMapping() {
            @Override
            protected void registerHandlerMethod(Object handler, Method method, RequestMappingInfo mapping) {
                // Custom logic to modify mapping metadata before registration
                super.registerHandlerMethod(handler, method, mapping);
            }
        };
    }
}
