Question

我正在尝试在针对QPID端点的请求 - 响应调用之间保存Camel Exchange上的值。

你可以从我的代码中看到我在调用端点之前设置了一个Header（和Property）。返回时，相同的标题和属性值为空。

我基本上想要跟踪fileName和filePath，以便我可以将结果写入同一位置

真的很挣扎。

includeAllJMSXProperties可能就是你要找的东西，

Camel 2.11.2 / 2.12：是否包含所有JMSXxxx属性从JMS映射到Camel消息。设置为true属性时如将包括JMSXAppID和JMSXUserID等。注意：如果您正在使用自定义headerFilterStrategy然后此选项不适用。

Apache Camel - 无法在请求 - 响应之间传播JMS标头属性
