Question

我正在尝试设计一个错误处理程序，它执行3次重新传递尝试，然后停止尝试。这是我的camel-context.xml：

<errorHandler id="logginghandler" type="DefaultErrorHandler">
  <redeliveryPolicy maximumRedeliveries="3" redeliveryDelay="5000"
retryAttemptedLogLevel="ERROR" />
</errorHandler>

  <route>
    <from uri="file:/home/user/files/in"/>
    <bean ref="mybean" method="doSomething"/>
    <to uri="jms:queue:myqueue"/>
  </route>
</camelContext>

当我执行Route时，Handler会不断尝试重新传递消息：

[ile:///home/user/files/in] DefaultErrorHandler            ERROR Failed delivery for (MessageId: ID-localhost-localdomain-47568-1462962389320-0-5 on ExchangeId: ID-localhost-localdomain-47568-1462962389320-0-6). On delivery attempt: 2 caught: java.lang.RuntimeException: Errore!

知道我缺少什么吗？

您有一个文件端点，因此代码会回滚您的文件，然后重新读取该文件。您可以尝试设置：noop = true（如果为true，则不会以任何方式移动或删除文件。此选项适用于只读数据）。这可能会解决您的问题。您可能想要设置的另一个选项是：moveFailed这将允许您在处理无法按预期工作时指定错误目录。
