Answer 1

Just implement ServletContextAware interface instead of directly autowiring ServletContext

@Service
public class DummyService implements ServletContextAware {

    ServletContext servletContext;

    @Override
    public void setServletContext(ServletContext servletContext) {
        this.servletContext = servletContext;
    }
}

The CometD integration with Spring Boot is documented here: https://docs.cometd.org/current/reference/#_java_server_services_integration_spring_boot.

You can find a fully working example here: https://github.com/cometd/cometd/blob/4.0.3/cometd-java/cometd-java-examples/cometd-java-examples-springboot/src/main/java/org/cometd/examples/spring/boot/CometDApplication.java.
