Spring状态机

Spring状态机 - 重用冲锋枪(Spring State machine - reuse Submachine)

我很难重新使用子机器图。

我需要重新使用一个状态机作为子机连接到一个状态，在另一个状态中作为子机。 但是当我给它引用时，我得到一个空指针异常。

我已经添加了对GeneralTopup的冲洗机参考，我想将其添加到注册。 但似乎不可能。 这是吗？

I have difficulty in re-using a sub-machine diagram.

I have a need to Re-Use one State machine that I have linked to a state as a sub-machine, in another state as a sub-machine. But when I give the reference to it I get a null pointer exception.

I Have added a submachine reference to GeneralTopup, I want to add the same to Register. But it seems impossible. Is this so?

最满意答案

这不会起作用，因为您需要在整个机器中具有唯一的状态，并且这会多次添加相同的状态。 话虽如此，这是一个长久以来我脑海中的想法，但我还不知道如何实现它。

This would not work as you need to have unique states in a whole machine and this would add same state multiple times. Having said that, it is a story what has been in my mind for a long time but I don't yet know how to implement it.
