how to get controller class name in interceptors for logging

Question

In my springboot application, we are logging controller requests/responses using the org.springframework.web.util.ContentCachingRequestWrapper and org.springframework.web.util.ContentCachingResponseWrapper. Refer below link for the sample code .

CustomLoggingFilter :

https://stackoverflow.com/a/42023374/1958669

There is a interceptor present in the application. Now the problem is while logging its only the interceptor name coming in className . So, for getting the actual controller name , I tried getting classname in interceptor . But that gives org.springframework.web.util.ContentCachingRequestWrapper.

CustomWebMvcConfig :

@Configuration
public class CustomWebMvcConfig implements WebMvcConfigurer {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new CustomLogInterceptor());
    }
}

CustomLogInterceptor :

public class CustomLogInterceptor extends HandlerInterceptorAdapter {
    private static final Logger logger = LogManager.getLogger(CustomLogInterceptor.class);

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception{
        //Some operation
    }
}

Getting logs in below format:

time="2019-03-18T09:59:51,001Z", thread="[o-auto-1exec-]" ,class=“a.b.c.CustomLoggingFilter ",message=“Payload_1“

time="2019-03-18T09:59:51,001Z", thread="[o-auto-1-xec-1]" ,class=“a.b.c.CustomLoggingFilter ",message=“Payload_2“"

My Question is how to get the actual ControllerClass name in logs instead of the LoggingFilterClass (one which uses the org.springframework.web.util.ContentCachingRequestWrapper)

Im getting logs in the below format ie classname is always CustomLoggingFilter , rather it should be actual controller name. `time="2019-03-18T09:59:51,001Z",thread="[o-auto-1-exec-1]",class=“a.b.c.CustomLoggingFilter ",message=“Payload_1“ time="2019-03-18T09:59:51,001Z",thread="[o-auto-1-exec-1]",class=“a.b.c.CustomLoggingFilter ",message=“Payload_2“` — shashantrika, Mar 18 '19 at 12:40
Then I suggest your best shot is to use an Aspect to do what you want. — akortex, Mar 18 '19 at 12:47
@Aris_Kortex : you have any reference links for aspect springboot rest api logging ? — shashantrika, Mar 25 '19 at 11:56

You can try with:

HandlerMethod handlerMethod = (HandlerMethod) handler;
String controllerName = handlerMethod.getBeanType().getSimpleName().replace("Controller", "");

Or if you want to print the URI:

request.getRequestURI();

I think you can't change the logger as you don't know who would be the controller.
