我正在使用 ActiveMQ 5.x，我想将 activemq.xml 代理中的一些内容提取到单独的文件中。注意：我不能使用<import>它不会工作。

我想在 activemq.xml 配置文件中使用 XInclude。

但是，当我尝试这样做时，出现错误“找不到元素 xi:include”

这是我正在使用的 activemq.xml 文件。你能帮我弄清楚如何包含外部文件吗？

活动MQ.xml

这不起作用。这是我得到的错误。

原因：org.xml.sax.SAXParseException：cvc-complex-type.2.4.c：匹配的通配符是严格的，但找不到元素“xi:include”的声明。

我也尝试使用实体定义，只是不知道如何让它工作。

请建议对 activemq.xml 进行更改以使其正常工作。谢谢！！

答案是——activemq 中不支持这个。

经过调查，我看到 Activemq 在 Spring 3.0 中不支持/打开 XInclude，它需要扩展 Spring XML 处理程序类来改变 DocBuilder 以允许 XIncludes。

我创建了一个新功能请求以建议添加此功能https://issues.apache.org/jira/browse/AMQ-3886

真可惜。
