我正在使用ActiveMQ和Atomikos建立Camel - 交易。在处理器中抛出RuntimeException时，我希望ActiveMQ重试该消息，但消息不会返回队列？请参阅下面的配置。

我得到的堆栈跟踪如下。在抛出RuntimeException之前，第一个Camel正在重试3次 - 事务被回滚，但队列中没有任何内容而且没有重试？

请参阅此页有关交易：http://camel.apache.org/transactional-client.html
如果你有一本Camel in Action书的副本，那么第9章就是交易。
您需要添加＆lt;转移/＆gt;在路线中，所以Camel使用TX管理器。

我稍微调试了一下配置，发现导致没有ActiveMQ重试的配置部分发生了。
以下使用JmsConfiguration不起作用。
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="amq.connectionFactory" />
<property name="transacted" value="true" />
<property name="transactionManager" ref="jta.transactionManager" />
</bean>
<bean id="jms" class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsConfig" />
</bean>
但是这样做。
<bean id="jms" class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="transacted" value="true" />
<property name="transactionManager" ref="jta.transactionManager" />
</bean>
不幸的是我现在无法让ActiveMQ选择redeliveryPlugin配置，但我看到在这个问题上引发了一个缺陷。有没有人知道一个解决方法？ 这是我认为的org.apache.activemq.ActiveMQXAConnectionFactory特有的。
干杯， 的Jesper
