I just encounter a problem when using spring state machine @WithStateMachine.

I just encounter a problem when using spring state machine @WithStateMachine.
@WithStateMachine just work when I use it on inner class which defined in the class annotated by @EnableStateMachine, but when I define class in other place it seems not work.
Here is my code:
`@Configuration @EnableStateMachine public class StateMachineConfig extends EnumStateMachineConfigurerAdapter { private Logger logger = LoggerFactory.getLogger(getClass());

@OverRide
public void configure(StateMachineStateConfigurer<States, Events> states)
throws Exception {
states
.withStates()
.initial(States.UNPAID)
.states(EnumSet.allOf(States.class));
}

@OverRide
public void configure(StateMachineTransitionConfigurer<States, Events> transitions)
throws Exception {
transitions
.withExternal()
.source(States.UNPAID).target(States.WAITING_FOR_RECEIVE)
.event(Events.PAY)
.and()
.withExternal()
.source(States.WAITING_FOR_RECEIVE).target(States.DONE)
.event(Events.RECEIVE);
}

@OverRide
public void configure(StateMachineConfigurationConfigurer<States, Events> config)
throws Exception {
config
.withConfiguration()
.autoStartup(true);
//.listener(listener());
}

//
//@bean
//public StateMachineListener<States, Events> listener() {
// return new StateMachineListenerAdapter<States, Events>() {
// @OverRide
// public void transition(Transition<States, Events> transition) {
// if (transition.getTarget().getId() == States.UNPAID) {
// logger.info("UNPAID");
// return;
// }
// if (transition.getSource().getId() == States.UNPAID
// && transition.getTarget().getId() == States.WAITING_FOR_RECEIVE) {
// logger.info("WAITING_FOR_RECEIVE");
// return;
// }
// if (transition.getSource().getId() == States.WAITING_FOR_RECEIVE
// && transition.getTarget().getId() == States.DONE) {
// logger.info("DONE");
// return;
// }
// }
// };
//}
@WithStateMachine
public class Action {
private Logger logger = LoggerFactory.getLogger(getClass());

@OnTransition(target = "UNPAID")
public void create() {
    logger.info("UNPAID");
}

@OnTransition(source = "UNPAID", target = "WAITING_FOR_RECEIVE")
public void pay() {
    logger.info("WAITING_FOR_RECEIVE");
}

@OnTransition(source = "WAITING_FOR_RECEIVE", target = "DONE")
public void receive() {
    logger.info("DONE");
}

}
}`
but when I define Action in another class file, it is not work.
My pom

org.springframework
spring-core
4.3.3.RELEASE


org.springframework
spring-messaging
1.2.3.RELEASE
