我的路线很小，我想使用自定义重新传递策略来重复向端点发送消息，但是这种行为很奇怪。看起来redeliveryPolicy仅重复引发错误。我试图将所有交换发送到路由的开始，但是随后该策略不起作用，因为每次都在创建：
<route id="sampleRoute">
<from uri="direct:anotheRoute" />
<to uri="nmr:kaboom" />
<choice>
<when>
<xpath>//result = 'true'</xpath>
<to uri="direct:anotherAnotherRoute" />
</when>
<otherwise>
<throwException ref="redeliveryException" />
</otherwise>
</choice>
<onException>
<exception>java.net.SocketException</exception>
<exception>java.net.ConnectException</exception>
<exception>my.custom.error.RedeliveryException</exception>
<redeliveryPolicy ref="customRedeliveryPolicy" />
<to uri="direct:anotheRoute" />
</onException>
</route>
我做错了什么？发生错误时，我希望每隔一段时间重复一次我的请求。我的骆驼版本是2.6

最佳答案
并不奇怪，骆驼的错误处理程序和重新交付从失败的步骤开始执行，而不是从路线开始执行。
您可以再次抛出错误调用direct:anotherRoute而不是抛出错误，唯一的问题是，如果过于频繁地执行此操作，则调用堆栈可能会变得很深。
您可以做的是将nmr:kaboom放入单独的路由中，并将其配置为具有noErrorHandler，然后从第一个路由中使用direct:进行调用，然后错误处理程序可以从以下位置重新传递整个路由开始。
