body: <p>I have this class and wants to log the rest-requests:</p>
  
  <pre><code>public class RequestFilter implements ContainerRequestFilter {
  
      private static final Logger LOG = LoggerFactory.getLogger(RequestFilter.class);
  
      @Override
      public void filter(ContainerRequestContext requestContext) throws IOException {
          LOG.info("REST-Request from '{}' for '{}'", "XXX", requestContext.getUriInfo().getPath());
          // ... and do some auth stuff (not relevant for this question)
      }
  }
  </code></pre>
