我们将XML DSL与Akka Camel(2.5.13)结合使用,发现当骆驼指向一个带有异常响应的bean时,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:

如果我使用的是一个仅返回错误的bean,那么它工作得很好,例如:
<bean id="forced" class="java.lang.Exception">
<constructor-arg index="0" value="This is forced"/>
</bean>
你知道是什么原因造成的吗?
