在HandlerInterceptor中获取RequestBody和ResponseBody [英] Get RequestBody and ResponseBody at HandlerInterceptor

问题描述

逻辑我必须实现的是记录所有请求，并将身体提供给DB。

Logic I have to implement is logging all requests with body served to DB.

所以我决定使用： afterCompletion HandlerInterceptor 的方法。
有两个参数传递给此方法 HttpServletRequest 和 HttpServletResponse 等等。

So I decided to use: afterCompletion method of HandlerInterceptor. There are two parameters passed to this method HttpServletRequest and HttpServletResponse among the others.

问题是：如何从提供的对象获取 RequestBody 和 ResponseBody ？

Question is: how to get RequestBody and ResponseBody from supplied objects?

据我所知，我们可以使用 @RequestBody 和 @ResponseBody 。我可以在 HandlerInterceptor 中重复使用它们吗？

As far as I know at Controller we can use @RequestBody and @ResponseBody. Can I reuse them at HandlerInterceptor?

推荐答案

据我所知， RequestBody 和 ResponseBody 只能读取一次。所以你不应该在 Interceptor 中阅读它们。
这里有一些解释。

As far as I know, RequestBody and ResponseBody can be read only once. So you should not read them in an Interceptor. Here's some explanation.
