【问题描述】:
在多播中抛出异常时,Camel 不会传播异常。
鉴于以下设置,direct:route 从其 beanRef 中抛出异常:
rest("/...")
.post()
.consumes("application/json")
.produces("application/json")
.route()
.onException(Exception.class)
.handled(true)
.bean("exceptionHandler")
.marshal("exceptionDataFormat")
.end()
.unmarshal("dataFormat")
...
.enrich("direct:services", new ServiceAggregator())
.to("direct:anotherRoute")
...
.end()
.endRest();
from("direct:services")
.errorHandler(noErrorHandler())
.multicast()
.setAggregationStrategy(new GroupedExchangeAggregationStrategy())
.executorServiceRef("executor")
.parallelAggregate()
.streaming()
.stopOnException()
.to("direct:route")
.end()
.end();
from("direct:route")
.errorHandler(noErrorHandler())
.bean("someRef", "someMethod")
.end();
我没有让异常处理程序消耗交换并处理错误,而是立即返回(到 SoapUI)以下异常:
org.apache.camel.CamelExchangeException: Parallel processing failed for number 0. Exchange[...] at org.apache.camel.processor.MulticastProcessor$1.call(MulticastProcessor.java:328)
at org.apache.camel.processor.MulticastProcessor$1.call(MulticastProcessor.java:299)

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
at java.lang.Thread.run(Thread.java:745)
并且父路由以该异常结束并且没有异常处理。
如果direct:anotherRoute 抛出异常,则该异常得到正确处理。
为什么我不能向父路由传播多播异常?
