Some queries on spring state machine.
Can we have more than one state machine in a single spring project, where in one state machine serves for one work flow (may be a CD player work flow) and the other for a turnstile?
Can I dynamically load the configuration in my config class, for instance from a big data source having JSON formatted data, where we stores our states, events, transitions etc.
One of my requirement is I may be having a frequently changing worklow or model, which I needs to configured in my spring project. How can I effectively do that with spring state machine.
1) You can have multiple machines. @EnableStateMachine has id property for a bean name. You can expose config as @EnableStateMachineFactory. If you want to work outside of javaconfig there is a manual builder model for it.
2/3) There is a public configuration api between javaconfig and statemachine. One user(outside of javaconfig) of this config model is uml based modeling which uses eclipse's uml xml file to load the config. Uml is your best bet as we don't have other build-in configuration hooks at this moment. contributions welcome ;)
