Question

我有下面的代码。fireTime标头在split之前可用，我也想在split调用之后使用它，这在每个日志中都不可用。 pom中的骆驼版本为2.17.3。代码和日志均如下所示。

@Override
    public void configure() throws Exception 
    {
        LOGGER.debug("Configuring client for UnicomOrderReader::synchInventoryAndOrders");

        from("quartz2://timer1?cron=0 0 * ? * * *")
            .log(" Unicom Job fired at ${header.fireTime}")
                .process(activeInitializedClientTaskProcessor)
                    .split(simple("${body}"))
                        .log("After Split Unicom Job fired at ${header.fireTime}")
                            .to("activemq:queue:" + ActiveMQNames.UNICOM_INVENTORY_ORDER_READER_QUEUE)
                                .log("Executed route to sync inventory and orders from Unicom ");
    }

记录如下输出：-

您可以将变量存储在属性中，并在链的后面使用它们，请参见下面的.setProperty("myHeader", header("theheadername"))：

@Override
public void configure() throws Exception 
{
    LOGGER.debug("Configuring client for UnicomOrderReader::synchInventoryAndOrders");

    from("quartz2://timer1?cron=0 0 * ? * * *")
        .log(" Unicom Job fired at ${header.fireTime}")
            .process(activeInitializedClientTaskProcessor)
            .setProperty("myHeader", header("theheadername"))
                .split(simple("${body}"))
//here you can access ${property.myHeader} for example by passing it as an argument to a bean method
                    .bean(myBean, "myMethod(${property.myHeader}, ${Body})")
                    .log("After Split Unicom Job fired at ${header.fireTime}")
                        .to("activemq:queue:" + ActiveMQNames.UNICOM_INVENTORY_ORDER_READER_QUEUE)
                            .log("Executed route to sync inventory and orders from Unicom ");
}

调用split后，如何将标头从父交换复制到子交换？
