是否可以在 XInclude 属性 href 中使用 Java 系统属性变量？

Question

我正在使用 ActiveMQ Artemis 拆分 broker.xml 功能并包含 xml 文件。我正在尝试使用 Java 系统属性作为 xml 文件路径。但它是抛出错误。

这是我正在尝试的行。

<xi:include href="${amq.conf.broker.config}/broker-security-settings.xml"/>

我单独定义了-Damq.conf.broker.config=/var/amq/....

出现以下错误

[Fatal Error] :116:82: An include with href '${amq.conf.broker.config}/broker-security-settings.xml'failed, and no fallback element was found.
org.xml.sax.SAXParseException; lineNumber: 116; columnNumber: 82; An include with href '${amq.conf.broker.config}/broker-security-settings.xml'failed, and no fallback element was found.

ActiveMQ Artemis 当前不支持在 include 元素的 href 中使用系统属性替换。但是，这似乎是一个不错的功能，所以我打开了 a new JIRA for it and sent a PR.
