Spring Batch：在运行时动态加载作业

Question

有没有办法在Spring Batch中动态加载作业？

我使用Spring应用程序上下文运行应用程序

我想在运行时动态加载以下作业：

<batch:job id="MyJob">
    <batch:description>MyJob Desc</batch:description>
    <batch:step id="step0_PromotionFetch" >
        <batch:tasklet ref="promotionFetch">
            <batch:transaction-attributes
                propagation="NEVER" />
        </batch:tasklet>
    </batch:step>
</batch:job>

我的代码：

DefaultListableBeanFactory beanFactory = (DefaultListableBeanFactory) configurableApplicationContext.getBeanFactory();

GenericApplicationContext genericApplicationContext = new GenericApplicationContext();
    XmlBeanDefinitionReader xmlBeanDefinitionReader = new XmlBeanDefinitionReader(genericApplicationContext);

    xmlBeanDefinitionReader.loadBeanDefinitions(configXMLFileName);

    BeanDefinition beanDefinition = xmlBeanDefinitionReader.getBeanFactory().getBeanDefinition("MyJob");

beanFactory.registerBeanDefinition("MyJob", beanDefinition);

我收到了错误：

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#315': Cannot create inner bean '(inner bean)' of type [org.springframework.batch.core.job.flow.support.StateTransition] while setting bean property 'stateTransitions' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#315': Cannot create inner bean '(inner bean)' of type [org.springframework.batch.core.job.flow.support.state.StepState] while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#315': Cannot resolve reference to bean 'step0_PromotionFetch' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'step0_PromotionFetch' is defined

这是正确的方法吗？
