Question

我正在尝试从defaultMuleMessage数据类型中提取值，但无法在Mule 3.7.3中获得正确的语法。有人可以帮忙吗？

我试图访问的值可以在Mule调试器的变量选项卡中找到：

initialMessage (org.mule.DefaultMuleMessage)
-> properties (org.mule.MessagePropertiesContext)
--> inboundMap (org.mule.util.CopyOnWrite.CaseInsensitiveMap)
---> 7 (java.util.Collections$UnmodifiavleMap$UnmodifiableEntrySet$UnmodifiableEntry)

7是键=组织

如果我在调试器中键入“initialMessage”，我会收到：

org.mule.DefaultMuleMessage
{
  id=6980b240-b882-11e6-85f7-d26120524153

我正在尝试检索“organization = abc”值。

Answer 1

如果您想使用MEL从mule消息获取入站属性（例如，名为organization），您只需：

#[message.inboundProperties.'organization']

Answer 2

我可以从问题和前一个答案的评论中得到。

您正在寻找MuleMessage的入站属性，该MuleMessage本身可作为您的流程消息中的属性。

尝试以下解决方案。

#[message.inboundProperties.'initialMessage'.getInboundProperty('organization')]

希望这有帮助。

Answer 3

尝试这样，＃[message.inboundProperties.organization]

从defaultMuleMessage获取值
