javaaop做⼀个接⼝耗时的计算看代码：
@Aspect
@Component
public class TimeCostAspect {
private static Logger logger = Logger(TimeCostAspect.class);
private static final String POINT = "execution (* com.ming..*.controller..*.*(..))";
@Pointcut(POINT)
public void performance() {
}
@Around("performance()")
public Object watchPerformance(ProceedingJoinPoint joinPoint) throws Throwable {
Object obj = null;
Object[] args = Args();
long startTime = System.currentTimeMillis();
obj = joinPoint.proceed(args);
java做什么的
if (!(obj instanceof BaseVO)) {
return obj;
}
long endTime = System.currentTimeMillis();
BaseVO baseVO = (BaseVO) obj;
baseVO.setCost(endTime - startTime);
return baseVO;
}
}
