获取以下异常（堆栈）：

加载mule' xml:时出现异常，原因是:org . XML . sax . sax parse exception:CVC-complex-type . 2.4 . a:发现以元素' file:inbound-endpoint '开头的无效内容。应为“{ http://www . mule soft . org/schema/mule/core”:abstract-message-processor，“http://www . mule soft . org/schema/mule/core”:abstract-outbound-endpoint，“http://www . mule soft . org/schema/mule/core”:abstract-mixed-content-message-processor }”中的一个。

为什么我不允许在选择路由器内发布文件到超文本传输协议？

Answer 1

此外，我认为还有另一个问题，即入站endpoint不允许动态输入。我通过MuleRequester解决了这个问题

Answer 2

问题是它是一个入站endpoint，因此您要在流的中间添加一个消息源。您应该做的是定义另一个以该文件入站endpoint（具有所有逻辑）开始的流，并在其选择中使用流引用元素。有关更多详细信息，请查看文档。

Answer 3

您只能在流的开头使用< code > file:inbound-endpoint 。如果您试图中途检索文件，那么可以考虑使用Mule Requestor模块。这允许您在流程中的任何点请求资源(即文件)。
