如何以有效的方式向客户端发送延迟响应

Question

I have requirement to mock some of the service calls, but i need to send response after waiting a period of time.

I know i can do this by using Thread.sleep(n) , but i'm not comfortable to make complete thread to sleep for certain time.

So i'm look if RestTemplate has any method like setResponseTime() to set Response delay time. or can i achieve this by using any another external dependency ?

Answer 1

You can use TimeUnit such as

- TimeUnit.NANOSECONDS.sleep(timeout);
- TimeUnit.SECONDS.sleep()
- TimeUnit.MINUTES.sleep()
- ....

Or you can explore the interface ScheduledExecutorService, they have a method name scheduleWithFixedDelay.
