Spring 状态机和 xml 配置

Question

我是 Spring Statemachine 框架的新手。可以在经典 XML 配置文件上使用配置吗？状态、事件和动作会更清晰。

Answer 1

根据我的文档：



static enum States {
    STATE1, STATE2
}

static enum Events {
    EVENT1, EVENT2
}

@Configuration
@EnableStateMachine
static class Config1 extends EnumStateMachineConfigurerAdapter<States, Events> {

    @Override
    public void configure(StateMachineStateConfigurer<States, Events> states)
            throws Exception {
        states
            .withStates()
                .initial(States.STATE1)
                .states(EnumSet.allOf(States.class));
    }

    @Override
    public void configure(StateMachineTransitionConfigurer<States, Events> transitions)
            throws Exception {
        transitions
            .withExternal()
                .source(States.STATE1).target(States.STATE2)
                .event(Events.EVENT1)
                .and()
            .withExternal()
                .source(States.STATE2).target(States.STATE1)
                .event(Events.EVENT2);
    }
}
@WithStateMachine
static class MyBean {

    @OnTransition(target = "STATE1")
    void toState1() {
    }

    @OnTransition(target = "STATE2")
    void toState2() {
    }
}

static class MyApp {

    @Autowired
    StateMachine<States, Events> stateMachine;

    void doSignals() {
        stateMachine.start();
        stateMachine.sendEvent(Events.EVENT1);
        stateMachine.sendEvent(Events.EVENT2);
    }

此示例使用 spring 注释进行配置。我会通过 XML spring 配置文件来配置它。

还没有，但我们有一些 github 问题来跟踪这些请求，即 gh78
