复杂单代理配置（仅限 STOMP）

<!--
  ActiveMQ Classic activemq.xml configuration file (/usr/local/activemq/conf/activemq.xml)

  * ActiveMQ Classic JVM Startup options are in /etc/activemq.conf

  * Uses the Sun JMX connector for remote management.  Point jconsole at:
    service:jmx:rmi:///jndi/rmi://myserver.domain.net:61616/jmxrmi

  * Uses Kaha persistence storage, stored in the "activemq-data" directory.
    "activemq-data" and "logs" sub-directories must be writable by the
    ActiveMQ Classic user.

  * Also see conf/log4j.properties for logging configuration
