如何知道goroutine是否仍然存在？

Question

Is there a comparable function like java Thread.isAlive() for goroutine?

I am trying to spawn some goroutine that is meant to be long living threads, but I am afraid that goroutine can die mid process, is there a check that I can do in my main thread to see if goroutine is alive?

No. You have to redesign your solution. Goroutines have no identity and cannot be accessed in any way.
