ActiveMQ Artemis桥接配置无效问题排查求助

配置的XML片段：

<bridge name="myBridge">
  <queue-name>jms.topic.my.special.queue</queue-name>
  <reconnect-attempts>-1</reconnect-attempts>
  <static-connectors>
    <connector-ref>kit1-connector1</connector-ref>
    <connector-ref>kit2-connector1</connector-ref>
    <connector-ref>kit3-connector1</connector-ref>
  </static-connectors>
</bridge>

启动时错误：

问题原因及解决方案 #

你的<bridge>节点直接作为核心配置的子元素，但ActiveMQ Artemis的XML schema要求所有桥接配置必须嵌套在<bridges>父节点内部，不能单独存在。错误信息里也明确列出了期望的元素包含{"urn:activemq:core":bridges}，这是关键提示。

修正后的配置示例：

<bridges>
  <bridge name="myBridge">
    <queue-name>jms.topic.my.special.queue</queue-name>
    <reconnect-attempts>-1</reconnect-attempts>
    <static-connectors>
      <connector-ref>kit1-connector1</connector-ref>
      <connector-ref>kit2-connector1</connector-ref>
      <connector-ref>kit3-connector1</connector-ref>
    </static-connectors>
  </bridge>
</bridges>

将原<bridge>节点放入<bridges>容器中，即可解决XML schema校验失败的问题。
