Answer 1

For RequestContext read this

 @Bean
    @ConditionalOnMissingBean(RequestContextListener.class)
    public RequestContextListener requestContextListener() {
        return new RequestContextListener();
    }

For the other listener is register automatically when you use spring-boot as this link implies.

For your own listeners.

public class MyAdditionListeners extends SpringBootServletInitializer {

    protected final Log logger = LogFactory.getLog(getClass());

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        WebApplicationContext rootAppContext = createRootApplicationContext(servletContext);
        if (rootAppContext != null) {
            servletContext.addListener(new YourListenerHere());
        }
        else {
            this.logger.debug("No ContextLoaderListener registered, as "
                    + "createRootApplicationContext() did not "
                    + "return an application context");
        }
    }

Finally there is a link in which you can find some information about listeners and SpringApplication class. Read section
