We have a few servlets like the one below, taking JSON request and produce JSON response. And the requirement is to log all API call traffic.import org.slf4j.*;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.IOException;public class CommentServlet {  private static final Logger LOG = LoggerFactory.getLogger(CommentServlet.class);  public void postComment(HttpServletRequest request, HttpServletResponse response) throws IOException {    String commentRequested = request.getParameter(comment);    LOG.info(commentRequested);    Object postResultModel = processComment(commentRequested);    JsonUtil.writeResponse(response, postResultModel);  }  /**  * doesn't reallty matter what processComment does  */  public Object processComment(String comment) {    return new Object();  }}import org.slf4j.*;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.fasterxml.jackson.databind.ObjectMapper;import java.io.IOException;public class JsonUtil {    private static final Logger LOG = LoggerFactory.getLogger(JsonUtil.class);    private static final ObjectMapper OBJECT_MAPPER = new ObjectMapper();    public static void writeResponse(HttpServletResponse response, Object modelObject) throws IOException {        String modelJson = OBJECT_MAPPER.writeValueAsString(modelObject);        LOG.info(modelJson);        response.setContentType(application/json);        response.getWriter().write(modelJson);    }}if you can mainly review how the logging is done, I'd like feedback on the general approach as much as whether there's any way to improve it.
