我需要分析骆驼路线上发生的异常。我已经配置了DeadLetterChannel:
<bean id="dlcHandlerForUpdateClientRequest" class="org.apache.camel.builder.DeadLetterChannelBuilder">
<property name="deadLetterUri" value="activemq:dlcUpdateClientRequest"/>
<property name="failureProcessor" ref="failureProcessorUpdateClientRequest"/>
</bean>
failureProcessor的作用是什么? 从deadLetterUri队列中读取消息后,故障处理器会启动吗?
