AOP实现执行时间获取

@Component
@Aspect//切面注解
public class RunTimeAOP {
    //所有的业务方式service
    @Around(value = "execution(* com.jt.service..*.*(..))")
    public Object around(ProceedingJoinPoint joinPoint) {
        Long startTime = System.currentTimeMillis();
        Object obj = null;

            obj = joinPoint.proceed();
            Long endTime = System.currentTimeMillis();
            Long runTime = endTime - startTime;
            String targetName = joinPoint.getSignature().getDeclaringTypeName();
            String methodName = joinPoint.getSignature().getName();
            Object[] args = joinPoint.getArgs();
            String kind = joinPoint.getKind();
            Object target = joinPoint.getTarget();
