啓動狀態機時出錯

在調用statemachine.start()時Iam總是得到下面的堆棧跟蹤，但它並沒有停止我的狀態機執行，因爲Iam沒有對狀態轉換，狀態條目等使用任何標註。請幫我解決這個問題錯誤。啓動狀態機時出錯

請包括導致此異常的代碼。沒有看到你在做什麼，幾乎不可能知道你做錯了什麼。 – Paul

這可能是一個解決方案嗎？ http://stackoverflow.com/questions/37925352/java-lang-illegalstateexception-bean-factory-must-be-instance-of-listablebeanfa – Paul

謝謝！此線程幫助我解決問題.http：//stackoverflow.com/questions/37925352/java-lang-illegalstateexception-bean-factory-must-be-instance-of-listablebeanfa – user2330825

爲此得到一個解決方案。

我將Spring應用程序上下文自動裝入我的類中。然後我從中提取AutowireCapableBeanFactory，並在構建器中設置它。具體如下：

@Autowired 
    private ApplicationContext appContext; 

    private void buildStateMachine() throws Exception { 
     Builder<EnquiryStatus, Event> builder = StateMachineBuilder.builder(); 
     builder.configureConfiguration().withConfiguration().beanFactory(appContext.getAutowireCapableBeanFactory()); 
    }
