I have a SpringBoot 2.6.14 WebApp and I’m using a Spring OncePerRequestFilter to log some information about the HTTP request and response.

The code is similar to the follow one:

@Slf4j(topic = "logger")
public class LoggingFilter extends OncePerRequestFilter {

  private final ObjectMapper mapper;

  public LoggingFilter(ObjectMapper mapper) {
      super();
      this.mapper = mapper;
  }

  @Override
  protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
        throws ServletException, IOException {
    
    ContentCachingRequestWrapper requestWrapper = new ContentCachingRequestWrapper(request);
    ContentCachingResponseWrapper responseWrapper = new ContentCachingResponseWrapper(response);

    ......

}

I manage to log the uri, the type of request (GET,POST ecc..) the host and some other usefull info but I can not manage to retrieve the Controller signature, or simply the name. Googling around I read that I can achieve this with an HandlerInterceptor but I must use a filter.

For example if I have a Controller like the follow one:

@RestController
@RequestMapping("/api/v1")
public class SomeController {

  @GetMapping("/all")
  public ResponseEntity<List<Some>> findAll() {
      List<Some> result = service.findAll();
      return new ResponseEntity<>(result, HttpStatus.OK);
  }
}

and I call it I can retrieve the path /api/v1/all but I would like to obtain even the findAll() method name.

Is it possible without the HandlerInterceptor?
