Exception 从一个camel路由继续异常，并在另一个camel路由中处理它

我有一个apachecamel路由，它调用restlet组件，并希望使用异常处理程序中的重新交付机制，该异常处理程序在每次失败时执行一些处理，以更新我的数据库记录，这应该在通用路由上完成。所以，我尝试在一个路由中继续异常，并通过direct组件在另一个路由中处理相同的异常。但例外情况并不是继续使用通用路线

第一条路线：

老实说：我看不出你的问题。

您的异常块不存在

<log id="_log1" message="Cont... ex >>>>> ${exception.message} "/>
<to uri="direct:ExceptionHandle"/>

所以一切正常。我是不是错过了什么

因评论而更新

只要第二条路由中没有异常发生，第二条路由的

onException

块就不会被调用。第二条路由通常接收并处理消息

您仍然可以使用

${exception}

访问消息上的异常信息，因为您已将日志语句显式添加到路由中，因此查看记录的内容将非常有用。否则，人们必须分析您的路由，以了解运行时可能发生的情况。@burki，请使用日志查找更新的查询。我已经处理了第二个路由中的异常，如何将第一个路由中发生的异常转移到第二个路由中，我已经处理了该异常。我真正需要的是，需要在单独的路径中处理异常和重新交付逻辑。现在我了解您的问题，我已经更新了我的答案
