尝试将OneException设置为全局,如下所示:
onException(Exception.class).handled(true)
.log("Exception Caught : ${exception.message}")
.end();
from("direct:remoteService")
.recipientList(constant("direct:route1, direct:route2"), ",").parallelProcessing().aggregationStrategy(new GroupedBodyAggregationStrategy())
.stopOnException()
.end()
.log("The final Exchange data : ${exception.message}")
;
UPD:因此您需要禁用收件人路由中的错误处理程序。请尝试类似(无法插入正常的代码示例)这是一个典型错误:(与拆分EIP完全相同)每个收件人将处理原始Exchange的副本。这些副本上的任何失败都不会影响(在上引发异常)处理主交换的路由,因为每个交换在一个完全独立的工作单元中运行。
如果启用“
shareUnitOfWork
”选项(在recipientList上),则应传播异常。这是可行的。但我们需要在路由范围本身处理异常。非常感谢。此方法与UPD中的方法一样有效,并且是一条新信息。现在尝试此方法,但无效。谢谢
