本文介绍如何配置ActiveMQ消息中间件，包括设置用户认证、调整内存和磁盘使用限制、限定最大连接数等关键参数。同时展示了如何通过配置文件activemq.xml启用多种协议的传输连接。

(1)修改activemq.xml配置,需要新增一个插件,在<broker>节点里面<systemUsage>节点前面添加如下

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" schedulePeriodForDestinationPurge="3600000">

        <destinationPolicy>
            <policyMap>
              <policyEntries>
                <policyEntry topic=">" >
                    <!-- The constantPendingMessageLimitStrategy is used to prevent
                         slow topic consumers to block producers and affect other consumers
                         by limiting the number of messages that are retained
                         For more information, see:

                         http://activemq.apache.org/slow-consumer-handling.html

                    -->
                  <pendingMessageLimitStrategy>
                    <constantPendingMessageLimitStrategy limit="1000"/>
                  </pendingMessageLimitStrategy>
                </policyEntry>
    <policyEntry topic=">" gcInactiveDestinations="true" inactiveTimeoutBeforeGC="3600000" />
    <policyEntry queue=">" gcInactiveDestinations="true" inactiveTimeoutBeforeGC="3600000" />
              </policyEntries>
            </policyMap>
        </destinationPolicy>

 
        <managementContext>
            <managementContext createConnector="false"/>
        </managementContext>

        
        <persistenceAdapter>
            <kahaDB directory="${activemq.data}/kahadb"/>
        </persistenceAdapter>

<plugins>
         	<simpleAuthenticationPlugin>
         		<users>
         			<authenticationUser username="${activemq.username}" password="${activemq.password}" groups="users,admins"/>
         		</users>
         	</simpleAuthenticationPlugin>
         </plugins>
          
          <systemUsage>
            <systemUsage>
                <memoryUsage>
                    <memoryUsage percentOfJvmHeap="70" />
                </memoryUsage>
                <storeUsage>
                    <storeUsage limit="100 gb"/>
                </storeUsage>
                <tempUsage>
                    <tempUsage limit="50 gb"/>
                </tempUsage>
				
            </systemUsage>
        </systemUsage>
