Spring Boot enable like in web.xml

Question

I have a problem with Spring Boot configuration. I got exception on some mobile devices which should use sockets:

java.lang.IllegalArgumentException: Async s

You just need to define dispatcherServlet @Bean:

@Bean
public ServletRegistrationBean dispatcherServlet() {
    ServletRegistrationBean registration = new ServletRegistrationBean(
            new DispatcherServlet(), "/");
    registration.setAsyncSupported(true);
    return registration;
}

It overrides that default one from DispatcherServletAutoConfiguration.
