我必须测量进入控制器的请求的全部时间，然后执行某个服务的异步方法：

@RestController
public class HelloController {

    @Autowired
    private SomeService someService;

    @GetMapping("/async")
    @Timed(value = "async.method.time", description = "Time taken to execute async method")
    public void async() throws InterruptedException {
        Thread.sleep(2000);

        someService.executeAsync();
    }
}

@Service
public class SomeService {

    @Async
    public void executeAsync() throws InterruptedException {
        Thread.sleep(2000);
        System.out.println("Async execution done!");
    }
}

实际上，如果我将@Timed注解放在async服务方法之上，那么它将被正确测量，但我也想用控制器方法测量时间。如何使用千分尺实现这一点？
先谢谢你了！
