Get RequestBody and ResponseBody at HandlerInterceptor

Question

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

So I decided to use: afterCompletion method of HandlerInterceptor

Answer 1

This is quite an old thread but for the sake of people who looking for a way to get RequestBody and ResponseBody from Interceptor. Here is how I got it working.

RequestBody, can simply use IOUtils:

String requestBody= IOUtils.toString(request.getInputStream(), StandardCharsets.UTF_8);

ResponseBody, I had to used HttpServletResponseCopier:

ServletLoggingFilter.HttpServletResponseCopier copier = (ServletLoggingFilter.HttpServletResponseCopier) response;
String responseBody = new String(copier.getCopy());
