Mule抛出错误：“someElement”元素上没有命名空间

我提供了我的代码片段，它应该正常工作，但事实并非如此。

简而言之，我的流程由石英触发，从数据库中读取一些数据，循环结果，在每个循环上执行某些操作然后完成。

当服务（http outbound）的结果返回没有任何东西可以返回时，一切正常，但是当选择（在流程中）不是默认值时，它会重定向到子流程，其中xslt执行并保存文件。文件保存就像它应该（我用外部工具检查，如果xml符合条件），记录器打印出3号作为证明它已完成（抛出错误之前的几行），但之后我得到下面给出的错误。谁知道为什么？我没有想法。

我的流程：

任何帮助表示赞赏！谢谢！

EDIT.1

我做了一些更多的研究，我发现问题是在我的循环（每个）结束时调用子流。我在flow-ref之后放了logger并打印好了直到那个错误（流程结束时生成文件但是记录器很安静）。那么，这个已知/未知的bug还是什么？或者我以某种方式重写在这里循环的集合：message.payload以便looper无法读取下一个值？但是，为什么在flow-ref之后的logger在结束时不会在循环内被触发？

1 个答案:

答案 0 :(得分：1)

cxf:proxy-client元素是一个“双向”元素，即它在请求和响应阶段处理消息。

“transform”子流影响消息有效负载，它是来自HTTP端点的响应，带有XSL-T。这会使cxf:proxy-client元素在最终得到响应回流时混淆。

一个可能的解决方法是在async块中引用子流，以便它将执行的任何有效负载转换对于调用流都不可见，但这将改变“msp2bass”的响应。 / p>

另一个选项是将byte-array-to-object-transformer和choice元素放在response上方的cxf:proxy-client块中，这样会影响CFX后的响应，这样就可以了停止抱怨。
