如何添加一个没有xml配置的RequestContextListener？

我需要在我的 Spring Boot应用程序中添加一个监听器,在web.xml中看起来像

<listener>
 <listener-class>
    org.springframework.web.context.request.RequestContextListener
 </listener-class>
</listener>

我使用no-web.xml配置,所以我有一个类似的

public class AppFilterConfig extends AbstractAnnotationConfigdispatcherServletinitializer {

@Override
protected Filter[] getServletFilters() {
    CharacterEncodingFilter filter = new CharacterEncodingFilter();
    filter.setEncoding("UTF8");
    filter.setForceEncoding(true);
    Filter[] filters = new Filter[1];
    filters[0] = filter;
    return filters;
}

private int maxUploadSizeInMb = 5 * 1024 * 1024; // 5 MB

@Override
protected Class<?>[] getRootConfigClasses() {
    return null;
}

@Override
protected Class<?>[] getServletConfigClasses() {
    return null;
}

@Override
protected String[] getServletMappings() {
    return new String[]{"/"};
}

@Override
protected void registerdispatcherServlet(ServletContext servletContext) {
    super.registerdispatcherServlet(servletContext);
    servletContext.addListener(new HttpSessionEventPublisher());

}

@Override
public void onStartup(ServletContext servletContext) throws servletexception     {

    super.onStartup(servletContext);
    servletContext.addListener(new RequestContextListener());
}

}

从上面的代码可以看出,我已经为onStartup(ServletContext servletContext)方法添加了一个监听器,但它仍然没有帮助,因为我仍然得到

In this case,use RequestContextListener or RequestContextFilter to expose the current request.

这条信息.如何正确地将侦听器添加到Spring Boot应用程序中？

我创建了这个类,这解决了我的问题.

@Configuration
@WebListener
public class MyRequestContextListener extends RequestContextListener {
}
