Question

我们有一个由多个子流组成的Mule流 - 为了更好地管理它，我们希望将子流复制到它们自己的单个文件中。在运行时，我得到以下错误，我想弄清楚。

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ParentFlow': Cannot create inner bean '(inner bean)' of type [org.mule.config.spring.factories.ScatterGatherRouterFactoryBean] while setting bean property 'messageProcessors' with key [1]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)': Cannot create inner bean '(inner bean)' of type [org.mule.config.spring.factories.FlowRefFactoryBean] while setting bean property 'messageProcessors' with key [1]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)': Invocation of init method failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'childflow' is defined

这是配置：

<flow name="ParentFlow" doc:name="ParentFlow">
    <flow-ref name="childFlow" doc:name="childFlow" />
</flow>
<sub-flow name="childflow" doc:name="childflow">
</sub-flow>

Answer 1

从您提供的配置中可以看出，ChildFlow的名称拼写不正确（大小写）。

子流的名称是“childflow”，而被引用的名称是“childFlow”

在流程参考中使用正确的名称“childflow”，它应该解决它。

Answer 2

你能展示你的代码吗？也许子流没有被正确引用或指向未定义的子流。

Mule - 将子流分成自己的流文件
