producer.xml配置部分：

<context:annotation-config/>

? ? <!-- ActiveMQ為我們提供的ConnectionFactory -->

? ? <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">

? ? <property name="brokerURL" value="tcp://localhost:61616"/>

? ? </bean>?

? ? <!-- spring jms 為我們提供連接池 -->??

<bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">

<property name="targetConnectionFactory" ref="targetConnectionFactory"/>

</bean>

每次一運行就報如下錯誤：

Exception in thread "main" org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.springframework.jms.connection.SingleConnectionFactory] for bean with name 'connectionFactory' defined in class path resource [producer.xml]; nested exception is java.lang.ClassNotFoundException: org.springframework.jms.connection.SingleConnectionFactory
