如何编写简洁的apache camel xml

Question

我是阿帕奇骆驼的新手。我已经将我的应用程序设置为使用基于XML的配置来使用Apache Camel。我的配置包含多个具有类似步骤集的路由。我试图找到一种方法，将这些不同路线的共同或重复部分放在一个地方，并从路线中引用它们，而不是一次又一次地重复它们？

<context:property-placeholder location="classpath:quartz.properties" />

<context:component-scan base-package="com"></context:component-scan>

    <camel:route>
        <camel:from uri="quartz://deadlines/SDGWD?cron=15+34+14+?+*+MON-SUN+*" />
        <camel:onCompletion>
            <camel:to uri="seda:checkAnyPendingDeadlines"/>
        </camel:onCompletion>
        <camel:to uri="bean:sdgwdNotifier" />
        <camel:choice>
            <camel:when>
                <camel:method ref="deadlineHandler" method="canProcessDeadline" />
                <camel:bean ref="deadlineHandler" method="prepareDeadline" />
                <camel:bean ref="sdgwdProcessor" method="initiateMessageProcessing" />
                <camel:bean ref="schedulerXdrTransformer" method="marshall" />
                <camel:to uri="wmq:SU.SES" />
                <camel:bean ref="sdgwdProcessor" method="waitForAcknowledgment" />
                <camel:bean ref="sdgwdProcessor" method="afterMessageProcessed" />
                <camel:bean ref="deadlineHandler" method="onDeadlineProcessingCompletion" />
            </camel:when>
            <camel:otherwise>
                <camel:bean ref="deadlineHandler" method="enqueDeadline" />
            </camel:otherwise>
        </camel:choice>
    </camel:route>


    <camel:route>
        <camel:from uri ="seda:checkAnyPendingDeadlines"/>
        <camel:onCompletion>
            <camel:to uri ="seda:checkAnyPendingDeadlines"/>
        </camel:onCompletion>
        <camel:to uri="bean:deadlineHandler?method=getNextProcessableDeadline" />
        <camel:choice>
            <camel:when>
                <camel:method ref="deadlineHandler" method="canProcessDeadline" />
                <camel:bean ref="deadlineHandler" method="prepareDeadline" />
                <camel:choice>
                    <camel:when>
                        <camel:simple>${body.deadline} == ${type:settlementcontrol.scheduler.model.Deadline.SDGW} </camel:simple>
                        <camel:bean ref="sdgwdProcessor" method="initiateMessageProcessing" />
                        <camel:bean ref="schedulerXdrTransformer" method="marshall" />
                        <camel:to uri="wmq:SU.SES" />
                        <camel:bean ref="sdgwdProcessor" method="waitForAcknowledgment" />
                        <camel:bean ref="sdgwdProcessor" method="afterMessageProcessed" />
                        <camel:bean ref="deadlineHandler" method="onDeadlineProcessingCompletion" />
                    </camel:when>
                </camel:choice>
            </camel:when>
            <camel:otherwise>
                <camel:bean ref="deadlineHandler" method="enqueDeadline" />
            </camel:otherwise>
        </camel:choice>
    </camel:route>

Answer 1

包含重复部分流程的公共路线是否足够？如果是，那么创建如下所示的内容：

<camel:route id="myCommonPartOfFlow">
   <camel:from uri="direct-vm:common-in"/>
   [common part]
</camel:route>

现在可以从主路由调用sub（myCommonPartOfFlow）路由：

<camel:to uri="direct-vm:common-in/>
