我们将 XML DSL 与 Akka Camel (2.5.13) 一起使用,发现当骆驼指向一个 bean 时,该 bean 以异常回答,它不会被 Camel 捕获。
我们的 Scala 代码:
private def replyError(exception: ChannelException) {
log.error(exception.error)
sender ! akka.actor.Status.Failure(exception)
}
我们的骆驼路线:
<route id="timer">
<from uri="timer://test?period=3000&delay=5000&repeatCount=0"/>
<doTry>
<to uri="AKKABEAN"/>
<doCatch>
<exception>java.lang.Exception</exception>
<log message="**********************************EXCEPTION HANDLED*******************************"/>
</doCatch>
</doTry>
</route>
在骆驼日志上:

如果我使用一个只返回错误的 bean,它工作得很好,例如:
<bean id="forced" class="java.lang.Exception">
<constructor-arg index="0" value="This is forced"/>
</bean>
知道是什么原因造成的吗?
