java Bean请求范围：Sping Boot 启动时未找到线程绑定请求

我正在尝试示例化一个请求范围内的简单缓存。

@Configuration
@EnableCaching
public class CacheConfiguration {

  @Bean
  @Scope(value = WebApplicationContext.SCOPE_REQUEST, proxyMode = ScopedProxyMode.TARGET_CLASS)
  public CacheManager requestCacheManager() {
    return new ConcurrentMapCacheManager("myValue");
  }
}

...

public interface MyRepository {

  @Cacheable(cacheNames = "myValue", cacheManager = "requestCacheManager")
  Integer getValue();

}

我希望应用程序能正确启动，但是它在启动时直接失败，没有任何请求发生。我不会在控制器的作用域之外调用MyRepository.getValue()。

在@Configuration类中添加如下内容：

@Bean(name = DispatcherServletAutoConfiguration. DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
    public DispatcherServlet dispatcherServlet (WebMvProperties webMvcProperties) {
        DispatcherServlet dispatcherServlet = new DispatcherServletO:
        dispatcherServlet.setDispatchOptionsRequest(webMvcProperties.isDispatchOptionsRequest());
        dispatcherServlet.setDispatchTraceRequest(webMvcProperties.isDispatchTraceRequest());
        dispatcherServlet.setThrowExceptionIfNoHandlerFound(webMvProperties.isThrowExceptionIfNoHandlerFound()); 
        dispatcherServlet.setPublishEvents(webMvcProperties.isPublishRequestHandledEvents());
        dispatcherServlet.setEnableLoggingRequestDetails(webMvcProperties.isLogRequestDetails());
        dispatcherServlet.setThreadContextInheritable(true);
        log. debug("init project dispatcher servlet")
        return dispatcherServlet;
    }

@Bean
    @ConditionalOnMissingBean({RequestContextListener.class, RequestContextFilter.class})
    @ConditionalOnMissingFilterBean(RequestContextFilter.class)
    public RequestContextFilter requestContextFilter() {
        OrderedRequestContextFilter orderedRequestContextFilter = new OrderedRequestContextFilter();
        orderedRequestContextFilter.setThreadContextInheritable(true);
        log.debug("init project request context filter!");
        return orderedRequestContextFilter;

    }
