QUESTION
I am trying to figure out how to easily use spring state machine including persistence with JPA. This is the problem I am dealing with:
Incompatible data types - factory and persistence
At a certain point in the program I would like to use the state machine which is connected to a user. There are repositories for that purpose (project spring-statemachine-data-jpa
).
At first there is a check if a state machine already exists for a player, using the repository. If not, creating a new state machine and persist it.
The problem is that I have different types of state machines. The factory creates a StateMachine
, the repository returns a JpaRepositoryStateMachine
. These are not compatible to each other and for me it is not clear how to persist / create / restore the state machines.
Can you please clarify that for me?

I am trying to configure the state machine from a yml File using a SpringStateMachine Builder. It works fine with the states and transition, but when I tried to include some child states, I'm getting the below exception.

Install spring-statemachine
You can use spring-statemachine like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the spring-statemachine component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
