Option to log HTTP request and response as a single message

[bgalek]

Hi!
One of my teams asked if our company spring boot starter could support logging requests
and responses in the same log message (extending CommonsRequestLoggingFilter)

Example:

>> INCOMING >> AFTER REQUEST  
Request: GET /api/endpoint?parameter=allegro-pl  
  Body: <empty body>  
Response: Status 200, took 5 ms  
  Body: {"works":true}  

I can think of some potential problems from that approach, BUT I wanted your opinion as CommonsRequestLoggingFilter maintainers!

Have you thought about this feature?
Maybe there was a decision made in spring team no to support such logging?

friendly ping :)

I don't think we ever had this enhancement request so far.
Given the very specific format, I think that you can achieve that by creating your own OncePerRequestFilter that wraps both the request and the response with ContentCachingRequestWrapper and ContentCachingResponseWrapper, then log once with the custom format you're looking for.

I guess we're not thinking about investing there now because the AbstractRequestLoggingFilter seems to work for most cases and if it doesn't it provides a base for extension.

@bclozel thank you!
