springboot中，如何利用AOP，实现函数执行时间打印并支持给annotation传递参数

需求：

利用AOP和annotation，实现当指定函数的执行时间超过阈值后，打印log

实现：

1，定一个带参数的annotation

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface LogExecutionTime {
    public int threshold() default 2000;
}

2，定义一个类，实现@Aspect和@Around

@Aspect
@Component
@Slf4j
public class PerformanceAspect {

    @Around("@annotation(timeLogger)")
    public Object logExecutionTime(ProceedingJoinPoint joinPoint, LogExecutionTime timeLogger) throws Throwable {
        final long start = System.currentTimeMillis();
        final Object proceed = joinPoint.proceed();
        final long executionTime = System.currentTimeMillis() - start;
        if (timeLogger.threshold() <= executionTime) {
            log.warn("LogExecutionTime -- {} executed in {} ms", joinPoint.getSignature(), executionTime);
        } else {
            log.debug("LogExecutionTime -- {} executed in {} ms", joinPoint.getSignature(), executionTime);
        }
        return proceed;
    }

}

3，使用自定义的annotation

    @LogExecutionTime(threshold = 2000)
    @Transactional(rollbackFor = Exception.class)
    public void submitAnswers(String flowNumber, ArrayList<Answer> allAnswers) throws Exception {
        

    }
