问题 I have used Spring state-machine in quite a complex scenario. I will explain my problem with the simplest part of the SM. Refer below image. This is my main state machine The state circled in red points to the following sub-machine So, as you can see, I have 3 actions. sendBasicTemplate, timeoutLogAction and processBasicTemplateReply. I will provide the related code segments and my configuration below. What I have observed during this process is that the state-machines created by the factory

Now I'm stuck at a point where I cannot think about any way of linking an exit point to it. The links to my model is given. https://drive.google.com/open?id=0B9PT7E5L1ac9LTZlZWV5bWx1V1U https://drive.google.com/open?id=0B9PT7E5L1ac9RnR6UUtrMkRoZE0 If you look at it, I have referenced a sub-machine from "DirectQuery" State (marked in red in the parent machine- img2). Now I have a problem

问题 This time I have a question about timeouts on the state machine. My scenario is like this, referring to the below image On entering StateBasic, I perform some action and the machine given by the Factory waits at WaitForTemplateResult till one of the events either VAS_QRY_RES or MAIN_QRY_RES. Now theres also a timeout which fires after 30seconds. So what happens now is the timeout is however fired even if VAS_QRY_RES or MAIN_QRY_RES comes. I studied this problem and the explanation I was able

In all examples I have looked up online, the StateMachine is configured statically @Override public void configure(StateMachineTransitionConfigurer<BookStates, BookEvents> transitions) throws Exception { transitions .withExternal() .source(BookStates.AVAILABLE) .target(BookStates.BORROWED) .event(BookEvents.BORROW) .and() .withExternal() .source(BookStates.BORROWED) .target(BookStates.AVAILABLE) .event(BookEvents.RETURN) .and() .withExternal() .source(BookStates.AVAILABLE) .target(BookStates.IN_REPAIR) .event(BookEvents.START_REPAIR) .and() .withExternal() .source(BookStates.IN_REPAIR) .target
