使用嵌入式ActiveMQ JMS进行Tomcat配置

Question

我有Tomcat 7.0.42和ActiveMQ 5.10，并将以下资源添加到我的context.xml文件中：

<Resource 
    auth="Container" 
    brokerName="MyActiveMQBrokerXML" 
    description="JMS Connection Factory" 
    factory="org.apache.activemq.jndi.JNDIReferenceFactory" 
    name="jms/ConnectionFactory" 
    type="org.apache.activemq.ActiveMQConnectionFactory" 
    useEmbeddedBroker="true"
    brokerURL="vm://localhost?brokerConfig=xbean:activemq.xml"
    />

当启动Tomcat via是内置启动脚本时，我在控制台输出中得到以下内容。

在我看来，tomcat不是在寻找activemq.xml文件，或者至少没有使用它。如果我通过eclipse启动tomcat，这个确切的配置是有效的，但这对于生产系统来说不是一个可行的选择。

我发现如果部署到生产中，您必须使用文件的绝对路径来让Tomcat找到activemq.xml文件。尽管使用相对路径应该可行，但我永远无法实现。

brokerURL="vm://localhost?brokerConfig=xbean:activemq.xml"

据说只有在你将'activemq.xml'添加到类路径时才有效。请注意'xbean：file：/some/path/activemq.xml'中存在'file'。

<Resource id="MyJmsResourceAdapter" type="ActiveMQResourceAdapter">
        BrokerXmlConfig =  xbean:file:/usr/share/apache-tomee-plus-8.0.0-M1/conf/activemq.xml
        ServerUrl       =  tcp://localhost:61616            
</Resource>
