Advice is an action taken by an aspect at a particular join point.

Different types of advice include “around,” “before” and “after” advice.

The main purpose of aspects is to support cross-cutting concerns, such as logging, profiling, caching, and transaction management.

@Aspect
@Component
public class PerformanceAspect {

    private Logger logger = Logger.getLogger(getClass().getName());

    @Pointcut("within(@org.springframework.stereotype.Repository *)")
    public void repositoryClassMethods() {};

    @Around("repositoryClassMethods()")
    public Object measureMethodExecutionTime(ProceedingJoinPoint pjp) throws Throwable {
        long start = System.nanoTime();
        Object retval = pjp.proceed();
        long end = System.nanoTime();
        String methodName = pjp.getSignature().getName();
        logger.info("Execution of " + methodName + " took " + 
          TimeUnit.NANOSECONDS.toMillis(end - start) + " ms");
        return retval;
    }
}
