Question

我有以下Mule ESB流程。它的目的是读取XML，映射它，然后通过HTTP post将一组字段提交给API。

我没有向API发送任何数据并且此错误消息。我相信我的问题是无法正确设置输出属性，例如这个区域。

org.mule.transformer.simple.MessagePropertiesTransformer：带有键＆＃39;区域＆＃39;的属性，在使用＆＃39;＃[message.outboundProperties [＆＃39; area＆＃39;]]的邮件中找不到＆＃39 ;.由于该值已标记为可选，因此未对此属性的消息设置任何内容

Answer 1

message-properties-transformers内的出站属性不太可能存在。 IIRC datamapper的出站属性被转换为流量变量。

这也可以解释整个message-properties-transformer的含义，因为就像现在一样，将VAR_X复制到VAR_X中。

Mule ESB XML映射到HTTP Post
