import lombok.extern.log4j.Log4j2;

@Aspect
@Log4j2
@Component
public class LogAdvice {
	
	@Before("execution(* com.kangong.sample.controller.SampleController*.*(..))")
	public void logBefore() {
		log.info("logBefore=========================================");
	}
	
	@AfterThrowing(pointcut = "execution(* com.kangong.sample.controller.SampleController*.*(..))", throwing="exception")
	  public void logException(Exception exception) {
	    
	    log.info("Exception....!!!!");
	    log.info("exception: "+ exception);
	  
	  }
	  
	  
	  @Around("execution(* com.kangong.sample.controller.SampleController*.*(..))")
	  public Object logTime( ProceedingJoinPoint pjp) {
	    
	    long start = System.currentTimeMillis();
	    log.info("Target: " + pjp.getTarget());
	    log.info("Param: " + Arrays.toString(pjp.getArgs()));
	    
	    
	    //invoke method 
	    Object result = null;
	    
	    try {
	      result = pjp.proceed();
	    } catch (Throwable e) {
	      // TODO Auto-generated catch block
