URL: https://github.com/apache/servicecomb-java-chassis/issues/2254


   
       public static HttpServletRequest getServletRequest() {
           ServletRequestAttributes requestAttributes = (ServletRequestAttributes)RequestContextHolder.currentRequestAttributes();
           return requestAttributes.getRequest();
       }
   
   	public static RequestAttributes currentRequestAttributes() throws IllegalStateException {
   		RequestAttributes attributes = getRequestAttributes();
   		if (attributes == null) {
   			if (jsfPresent) {
   				attributes = FacesRequestAttributesFactory.getFacesRequestAttributes();
   			}
   			if (attributes == null) {
   				throw new IllegalStateException("No thread-bound request found: " +
   						"Are you referring to request attributes outside of an actual web request, " +
   						"or processing a request outside of the originally receiving thread? " +
   						"If you are actually operating within a web request and still receive this message, " +
   						"your code is probably running outside of DispatcherServlet: " +
   						"In this case, use RequestContextListener or RequestContextFilter to expose the current request.");
   			}
   		}
   		return attributes;
   	}
   
   attributes  为空 ，因为cse定义了自己的上下文，对于这种依赖spring上下文如何处理。

   这类问题需要结合业务场景和目的进行分析和设计方案，即使用RequestAtrributes做什么事情，达到什么目的，然后寻找替代方案。 通常会用到Context参数， 参考：https://docs.servicecomb.io/java-chassis/zh_CN/build-provider/catalog/
