Question

我有一条骆驼路线，它会自称直到满足特定条件。基本上，这个想法是实现路由重试。部署应用程序时，如果重试时间很长，我会收到stackoverflow错误。

我相信stackoverflow错误是由于路由的递归调用引起的，我更改了路由结构，现在重新交付由骆驼onException()中可用的retryDelivery机制处理。在条件满足之前，我的重试次数可以是无限的。

我需要知道这种方法再次stackOverFlow的可能性。

Answer 1

否，这是使用onException和其他错误处理功能来处理错误处理重新交付的正确方法。使用循环EIP会导致更长的堆栈帧，因此不应将其用于循环时间过长的情况。所以您做了正确的修复。

camel：递归调用路由时，stackoverflow错误
