彈簧狀態機轉換

Question

我試圖觸發從其他過渡到自動狀態機（SM）的轉換，但無法正常工作：初始動作（findCustomer（））應該更改SM的初始狀態，然后每個動作都會觸發一個事件，依此類推最終狀態。 這是我的配置：

    @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);
        };
    }
}

Answer 1

你有事件CardEvents.FIND_CUSTOMER為CardStates.ACTIVE_STATUS到CardStates.CUSTOMER_FOUND 。 從findCustomer()發送事件CardEvents.CUSTOMER_FOUND比不同CardEvents.FIND_CUSTOMER 。

更改它，我認為它應該起作用。 想一想，我個人更希望通過匿名轉換和選擇狀態來驅動automatic機器。
