错误原因

ActiveMQ未允许传输序列化对象

解决方法

在targetConnectionFactory中添加

<property name="trustAllPackages" value="true"/>

完整配置

    <!-- 真正可以产生Connection的ConnectionFactory，由对应的JMS服务厂商提供 -->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://localhost:61616"/>
        <!-- 如果传输对象，必须设置这句为true -->
        <property name="trustAllPackages" value="true"/>
    </bean>
