问题描述

我正在使用提供的生成器创建状态机对象，如下所示:

I'm creating a state machine object using the provided builder as follows:

10.2 State Machine via Builder

I'm seeing the following exception:

该异常不会阻止状态机按预期运行.但是，我想深入了解为什么看到这一点.

The exception isn't preventing the state machine from functioning as expected. However, I would like to get down to the bottom of why I'm seeing this.

有人知道如何阻止此异常显示吗?

Anyone know how I can stop this exception from showing?

谢谢.

推荐答案

已设法解决此问题.

我将Spring应用程序上下文自动连接到我的类中.然后，我从中提取AutowireCapableBeanFactory并将其设置在构建器中.如下:

I autowired the the Spring application context into my class. I then extracted the AutowireCapableBeanFactory from this and set this up inside the builder. As follows:

   @Autowired
    private ApplicationContext appContext;

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