我有一个接受消息的Netty4接口并将此消息放入队列（ActiveMQ），如果在运行camel时队列的连接已关闭，那么在接收到调用者的消息后，Netty中发生异常无法捕获任何OnException和任何ErrorHandler，我尝试使用LoadBalance和故障转移，但仍然是同样的问题，在这种情况下的问题是调用者正在等待超时，即使恢复与队列的连接，Camel正在失去来电者的留言并没有继续路线（这是最糟糕的问题）。
我的路线：
<route id="GetHl7Request">
<from uri="hl7listener" />
<transacted />
<multicast>
<to uri="direct:SaveRequestInMQChannel" />
<to uri="direct:AckToOrderSrcChannel" />
</multicast>
</route>
<route id="SendRequestToMQ">
<from uri="direct:SaveRequestInMQChannel" />
<inOnly uri="inboundMQ" />
<log logName="{{camel.general.info.logname}}" loggingLevel="INFO"
message="HL7 Request from OrderSrc has been Saved to MQ" />
</route>
<route id="AckToOrderSrcHL7Request">
<from uri="direct:AckToOrderSrcChannel" />
<to uri="bean:HL7Processor?method=sendAckToOrderSrc" />
</route>
