我有一条复杂的路线,如下所示(部分):
.when(header("KEY_1").isNull())
.choice()
.when(header("KEY_2").isNull())
.split().method(SplitExample.class, "invokeSplitter").streaming().parallelProcessing().executorService(threadPoolExecutor) // first split
.policy(requires_new)
.bean(SplitExample.class, "enrich")
.bean(persister,"populateRecordAndXRef")
.bean(initializer, "initialize")
.bean(validator, "validateInMsg")
.bean(suppressResolver, "resolve")
.choice()
.when(header("KEY_3").isNull())
.bean(MsgConverter.class,"doInvoke" ) // #1 property or header set here
.split(body()) // second split
.bean(validator, "validateOutMsg")
.to(toURI.toArray(new String[ toURI.size()]))
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
System.out.println(exchange.getException()); // #2 queue server is shut down here so that transaction failure occurs
}
})
.endChoice() //end when
.end() //end choice
.end() //end policy
.end() //end split
.endChoice() //end when

我还定义了以下异常策略:
onException(JMSException.class)
.handled(true)
.process(new QueueOperationFailureProcessor()); // #3 property or header should be accessible here

现在,我的意图是在中将一个bean设置为Exchange属性(“ RECOVERY_DETAIL”),MsgConverter (#1)并在中检索相同的bean QueueOperationFailureProcessor (#3)。
通过调试,我可以在中看到属性(“ RECOVERY_DETAIL”)in-line processor (#2)。在JMSException上,当我的异常策略生效时,我想检索中的属性(“ RECOVERY_DETAIL”)QueueOperationFailureProcessor (#3)。
但是,碰巧的是-可用的Exchange与所在的Exchange QueueOperationFailureProcessor (#3)不同,in-line processor (#2)并且找不到属性(“ RECOVERY_DETAIL”)。
请帮帮我。
PS我的骆驼版本为2.16.0,我可能无法使用需要版本升级的任何解决方案。
