Active MQ 傳輸 ObjectMessage 異常

<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">  
        <property name="brokerURL" value="tcp://localhost:61616"/>
        <!-- 如果傳輸的對象是Obeject 這里必須加上這句  否則會導致對象序列化失敗 出現classnotfound異常  詳細： http://activemq.apache.org/objectmessage.html -->
        <property name="trustAllPackages" value="true"/>
    </bean>  

在消費者接受隊消息時，出現異常

javax.jms.JMSException: Failed to build body from content. Serializable class not available to broker. Reason: java.lang.ClassNotFoundException: Forbidden class com.guesslive.admin.common.mail.Mail! This class is not trusted to be serialized as ObjectMessage payload. Please take a look at http://activemq.apache.org/objectmessage.html for more information on how to configure trusted classes.

然后根據提供的地址找了下原因，在 ActiveMQConnectionFactory 中加入參數 

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

問題解決！
