ActiveMq池

有两种连接方式

1.Spring  引用

<!-- 配置JMS连接工厂 -->
    <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory"
        destroy-method="stop">
        <property name="connectionFactory">
            <bean class="org.apache.activemq.ActiveMQConnectionFactory">
                <property name="brokerURL">
                    <value>failover:(tcp://192.168.2.211:62617,tcp://192.168.2.211:62618,tcp://192.168.2.211:62619)?maxReconnectAttempts=10</value>
                </property>
                <property name="useAsyncSend">
                    <value>true</value>
                </property>
            </bean>
        </property>
    </bean>

2.配置文件

MqUserName=admin
MqPassword=admin
MqUrl=failover:(tcp://192.168.2.211:62617,tcp://192.168.2.211:62618,tcp://192.168.2.211:62619)
