有没有办法从Java servlet处理程序获取原始http请求流？

我正在尝试将一些日志记录捕获到我的应用程序的原始http请求。我的Java代码在SpringMVC控制器中。我可以访问HttpServletRequest对象。但我找不到一种方法来获取原始的http请求流。有一个读者，但只阅读帖子内容。我想要的是整个shebang，url，标题，身体。是否有捷径可寻？

I am trying to put some logging to capture the raw http request coming to my application. My Java code is inside a SpringMVC controller. I have access to the "HttpServletRequest" object. But I could not find a way to get the raw http request stream out of it. There is a reader but only reads the post content. What I want is the whole shebang, the url, the headers, the body. Is there an easy way to do this?

提前致谢。
