当Camel被抛出多播时,它不会传播异常。
给出以下设置,其中direct:route
从其beanRef:
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();
不是允许异常处理程序使用交换并处理错误,而是立即返回以下异常(到SoapUI):
org.apache.camel.CamelExchangeException: Parallel processing failed for number 0. Exchange[...] at org.apache.camel.processor.MulticastProcessor$1.call(MulticastProcessor.java:328)

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,则会正确处理该异常。
为什么我不能将多播异常传播到父路由?

打开多播上的shareUnitOfWork
选项。有关详细信息,请参阅:http://camel.apache.org/multicast并且分割器上有一个示例,它也有此选项:http://camel.apache.org/splitter.html

尝试使用
.errorHandler(noErrorHandler())
在父路由和子路由中将异常传播到 onexception()
