Examples on configuring Spring State Machine and how to test the state machine.

Default State Machine Factory

In this example, MailingStateMachineConfig where all states and events are configured in that configuration file.

• How to Run:

  • mvn clean compile spring-boot:run.

• Pros:

  • For simple state machine, it's simple to configure.

• Cons:

  • For complex state machine, the states/events/actions configuration can get very tedious.
  • Difficult to get "full picture" of the state machine containing many states and pseudo-states.

UML-Based State Machine Factory

In this example, MailingUmlStateMachineConfig is used where all states and events are configured in the UML file using Eclipse Papyrus.

• How to Run:

  • mvn clean compile spring-boot:run -Drun.profiles=uml

• Pros:

  • The UML file becomes a living documentation of the state machine.
  • Easy to understand the entire state machine through UML visualization.

• Cons:

  • Learning curve to create the UML file using Eclipse Papyrus.
  • States and events must be type String instead of Enum.
