OnException maximumRedeliveries被忽略

问题描述

在以下路由中，当我们得到异常时，将忽略来自redeliveryPolicy的maximumRedeliveries子句.我们得到:

In the following route, the maximumRedeliveries clausule from redeliveryPolicy is ignored when we get an exception. We get:

(ExchangeId:ID-UW205584-58231-1527668174534-39-24上的(MessageId:ID-UW205584-58231-1527668174534-39-248)传递失败.尝试送货时:0

然后它保持在无限循环中，重复最后一次重试.任何的想法?非常感谢社区！

And then it remains in a infinity loop repeating the last retry. Any idea? Thank you very much community!

我们的路线如下:

<?xml version="1.0" encoding="ASCII"?>
<routes xmlns="http://camel.apache.org/schema/spring">
    <route handleFault="true">
        <from uri="switchyard://ProcessTaskEx"/>

        <to uri="switchyard://RequestCapacity"/>
        <onException>
            <exception>java.lang.Exception</exception>
             <exception>webservicequeues.utilities.WebServiceQueueException</exception>

            <redeliveryPolicy maximumRedeliveries="2" redeliveryDelay="6000" maximumRedeliveryDelay="90000" retriesExhaustedLogLevel="INFO" retryAttemptedLogLevel="INFO"/>
            <handled>
                <constant>true</constant>
            </handled>

            <log message="Failed after Retry.Sending ProcessTask Request to Error Queue" loggingLevel="ERROR" logName="WebServiceQueues" />
            <to uri="switchyard://ErrorProcessTaskExQueue"/>
        </onException>
    </route>
</routes>

推荐答案

由于您遇到无限循环，因此听起来好像消息头CamelRedeliveryCounter每次都被覆盖，因此它永远不会达到2的maximumRedeliveries.

Because you get an infinite loop, it sounds like the message header CamelRedeliveryCounter gets overwritten every time and therefore it never reaches the maximumRedeliveries of 2.

对发生错误的端点的调用是否有可能删除或重置消息头?特别是CamelRedeliveryCounter?

Is it possible that the call to the endpoint where the error occurs deletes or resets message headers? Particularly CamelRedeliveryCounter?
