我试图触发从其他状态机的转换以制作自动状态机 (SM) 但它不起作用：初始操作 (findCustomer() ) 应该更改 SM 的初始状态，然后每个操作触发一个事件，依此类推最终状态。这是我的配置：
@Configuration @EnableStateMachine public class CardStateMachineConfig extends EnumStateMachineConfigurerAdapter<CardStates, CardEvents> {
final private static Logger logger = LoggerFactory.getLogger(CardStateMachineConfig.class);
@Override
public void configure(StateMachineStateConfigurer<CardStates, CardEvents> states) throws Exception {
states.withStates().initial(CardStates.ACTIVE_STATUS).state(CardStates.ACTIVE_STATUS, findCustomer(), null)
.states(EnumSet.allOf(CardStates.class));
}
// @formatter:off
@Override
public void configure(StateMachineTransitionConfigurer<CardStates, CardEvents> transitions) throws Exception {
transitions.withExternal().source(CardStates.ACTIVE_STATUS).target(CardStates.CUSTOMER_FOUND).event(CardEvents.FIND_CUSTOMER).action(findCustomer())
.and().withExternal()
.source(CardStates.CUSTOMER_FOUND).target(CardStates.MOBILECARD_FOUND).event(CardEvents.CUSTOMER_FOUND).action(findMobileCard())
.and().withExternal()
.source(CardStates.FIND_MOBILECARD_FOUND).target(CardStates.WIRECARD_LOCKED_CARD).event(CardEvents.MOBILE_CARD_FOUND).action(wirecardLockCard());
}
// @formatter:on
@Override public void configure(StateMachineConfigurationConfigurer<CardStates, CardEvents> config)
throws Exception {
config.withConfiguration().autoStartup(true).listener(new MobileCardBlockProcessEventHandler());
}
@Bean public Action<CardStates, CardEvents> findCustomer() {
return (context) -> {
context.getStateMachine().sendEvent(CardEvents.CUSTOMER_FOUND);
};
}
@Bean public Action<CardStates, CardEvents> findMobileCard() {
return (context) -> {
context.getStateMachine().sendEvent(CardEvents.MOBILE_CARD_FOUND);
};
}
}
