Question

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：我无法使用<import>它无效。

我想在activemq.xml配置文件中使用XInclude。

然而，当我尝试这样做时，我收到错误“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获得外部文件吗？

activemq.xml中

传输connectors.xml

这不起作用。这是我得到的错误。

引起：org.xml.sax.SAXParseException：cvc-complex-type.2.4.c：The 匹配通配符是严格的，但是找不到声明 element'xi：include'。

我也尝试过使用实体定义，但却无法弄清楚如何使用它。

请建议对activemq.xml进行更改以使其生效。谢谢！

Answer 1

答案是 - 在activemq中没有对此的支持。

经过调查，我发现Activemq在Spring 3.0中没有支持/启用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，建议添加https://issues.apache.org/jira/browse/AMQ-3886

无赖。

ActiveMQ 5.x - XInclude似乎不适用于配置文件
