Apache camel Apache Camel:处理封装在GenericFileOperationFailedException中的unix文件权限错误

这是我已经解决了一段时间的问题…我正在使用Camel（v2.10.2）设置许多文件路由，以便跨文件系统、服务器和组织内外（B2B）移动数据。在各自的dir中有数据和信号文件，其中一些路由是短期的，而其他路由则作为服务在不同的vm/服务器上运行。这些进程（路由）在不同的unix“功能”ID下运行，但有人试图使它们属于相同的unix组（如果可能的话）

当然，在unix上，总是有可能出现文件/dir权限问题……这就是我正在面临/试图解决的问题

我使用

DefaultErrorHandler

并通过

onExchangeDone（…）

中的自定义

RoutePolicy

记录交换的成功或失败，检查

exchange.isFailed（）

。信号文件在成功时移动到目标位置，或在失败时移动到

.error

dir，并将警报写入系统范围的警报日志（由Tivoli检查）

文件路由配置为通过

consumer.bridgeErrorHandler=true

基本上，如果我有任何与unix权限相关的错误，那么我希望停止（或者删除）受影响的路由，清楚地表明这已经发生以及原因-权限问题不容易通过编程解决，因此停止并发出警报是唯一的选项

所以我将演示一个导致问题的测试用例

应用程序A在/data/中创建一些数据文件。然后，App_A在/signal/中创建了相同数量的信号文件，但由于一些与“数据”相关的错误，它还创建了一个没有相应数据文件的信号文件/signal/acc_xyz.csv

路由开始处理/signal/acc_xyz.csv，“验证过程”发现/data/acc_xyz.csv不存在，并抛出异常以指示此情况，从而停止进一步处理的交换

文件

组件配置了

moveFailed=.error

以将信号文件移动到/signal/.error/，但该目录被锁定（不用担心为什么会被锁定）对于执行Java进程和内部Camel处理的功能用户id，会抛出一个

GenericFileOperationFailedException

，指示潜在的“权限被拒绝的问题的原因

哦，天哪，同样的信号文件会被一次又一次地处理，然后

我试图将此“次要错误”传播到我的代码中，但失败了，因此无法停止路由

如何将此错误和其他内部Camel错误传播到我的代码/异常处理程序/任何东西，而不只是看到它被记录和吞没

提前谢谢

好的，从log4j获得更多细节…注意时间顺序

文件被一次又一次轮询，因为它未被移动，因此仍然存在于该位置。我想您必须获得路由（可能来自上下文）并从异常处理程序中调用stop方法。@U2one:这正是我想要做的，除了Camel似乎没有宣传包装IO权限问题的-我将称之为次要或内部-异常…这里有一个log4j错误跟踪-注意timesok不是v2.X中的一个功能，可能是v3.X中的一个功能…似乎是一个相当基本的功能，这是必需的。。。这里有更多信息……但在此期间，//URI文件需要设置

&consumer.exceptionHandler=#myExceptionHandler

——即使我读了无数遍，我还是错过了这个：(
