我的 dataweave 代码配置 xml 如下:
<dw:transform-message doc:name="Transform Message">
<dw:set-payload resource="#[flowVars['sample']]" />
</dw:transform-message>
其中 sample 是一个流变量,其中包含具有实际转换逻辑的 .dwl 文件的文件路径。
<set-variable doc:name="Variable" value="file:D:/Transformer/sample.dwl" variableName="sample"/>
我在部署应用程序时看到的错误如下:
