java - jmxagent 在添加到 Camel 上下文中时抛出 saxparse 异常

Question

我在我的camelcontext.xml中添加了以下代码片段

<jmxAgent id="agent" createConnector="true" />

但是上面添加的代码在将其部署到 Jboss 实例中时出现以下异常:

以下是我的完整的camelcontext.xml:

 <jmxAgent id="agent" createConnector="true" statisticsLevel="RoutesOnly"/>

</camelContext>
</beans>`

我使用的camel版本是2.23.2。我还对 Camel 有以下依赖:

    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-jmx</artifactId>
        <version>${camel.version}</version>
    </dependency>`

我更改了camel spring xsds，但问题仍然存在

我认为问题在于 jmxAgent 标记的顺序。将 jmxAgent 标记放在 camelContext 标记的开头。检查camel-spring.xsd你会发现

  <xs:extension base="tns:abstractCamelContextFactoryBean">
    <xs:sequence>
      ....
      <xs:element minOccurs="0" ref="tns:packageScan"/>
      <xs:element minOccurs="0" ref="tns:contextScan"/>
      <xs:element minOccurs="0" ref="tns:streamCaching"/>
      <xs:element minOccurs="0" ref="tns:jmxAgent"/>
      .....
      <xs:element maxOccurs="unbounded" minOccurs="0" ref="tns:routeContextRef"/>
      <xs:element maxOccurs="unbounded" minOccurs="0" ref="tns:restContextRef"/>
      <xs:element maxOccurs="unbounded" minOccurs="0" ref="tns:threadPoolProfile"/>
      <xs:element maxOccurs="unbounded" minOccurs="0" ref="tns:threadPool"/>
      <xs:element maxOccurs="unbounded" minOccurs="0" ref="tns:endpoint"/>
      .....
   </xs:sequence>
  </xs:extension>
