Spring AOP Aspect to log ip address and User Id

LoggingAspect.java

@Aspect
@Component
public class LoggingAspect {

    @Before("execution(* com.example.controller.*.*(..))")
    public void before(JoinPoint joinPoint) {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        MDC.put("ip", request.getRemoteAddr());
        MDC.put("userId", request.getHeader("userId"));
    }

    @After("execution(* com.example.controller.*.*(..))")
    public void after() {
        MDC.remove("ip");
        MDC.remove("userId");
    }
}

this works like a charm!! thanks mate. just check for the null point on RequestContextHolder.getRequestAttributes()
