Question

我有一个最初未启动的计时器路由。我想从另一条路线激活它。我正在尝试使用骆驼的controlbus EIP模式。

// From my other route
.to("controlbus:route?routeId=fileConsumerRoute&action=start&async=true")

from("timer://camel-fileConsumerRoute?fixedRate=true&period=5s")
    .routeId("fileConsumerRoute").noAutoStartup()
    .log("Route is running");

我在控制总线后部的日志中看到正在恢复路由

上下文操作：[恢复]

，但计时器仍不触发。我看不到日志行“路由正在运行”

如何通过Controlbus激活计时器端点？

是否有另一种EIP模式或不同的方式来实现激活计时器端点？

Answer 1

我知道我参加晚会很晚，但是，您可以使用Controlbus或类似的起止路线。如果有谓词，则进行其他布尔测试。

示例：

我们测试每个周期是否存在某种条件，并根据条件的结果执行操作...

<!-- Token Database -->
<route autoStartup="true" id="core.predix.tkndependencyCheckerRoute">
    <from id="_from2" uri="timer://tkndbAvailable?fixedRate=true&amp;period=30000"/>
    <process id="_process2" ref="tkndbAvailableProcessor"/>
</route>

public class TknDbAvailableProcessor implements Processor {

    private static final Logger LOG = LoggerFactory.getLogger(TknDbAvailableProcessor.class);

    private TKNDataService tknDataService = null;

    @Override
    public void process(Exchange exchange) throws Exception {

        ServiceStatus status = exchange.getContext().getRouteStatus("core.fleet.EnrichmentRoute");  

        if (null == tknDataService) {

            if (status.isStarted()) {
                exchange.getContext().stopRoute("core.fleet.EnrichmentRoute");  
            }           
        } else {

            if (tknDataService.isTKNDataServiceAvailable()) {

                if (status.isStopped()) {
                    exchange.getContext().startRoute("core.fleet.EnrichmentRoute");  
                }
            } else {

                if (status.isStarted()) {
                    exchange.getContext().stopRoute("core.fleet.EnrichmentRoute");  
                }
            }
        }
    }

    public void setDataService(TKNDataService dataService) {
        this.tknDataService = dataService;
    }

}

如果需要主单例路由（如果需要冗余）-在差异节点上，请使用带有ControlBus的JGroups群集

<bean class="org.apache.camel.component.jgroups.JGroupsFilters"
    factory-method="dropNonCoordinatorViews"
    id="dropNonCoordinatorViews" scope="prototype"/>
<bean class="org.apache.camel.component.jgroups.JGroupsExpressions"
    factory-method="delayIfContextNotStarted"
    id="delayIfContextNotStarted" scope="prototype">
    <argument value="5000"/>
</bean>

<route autoStartup="true" id="FleetMainClusterControlRoute">
    <from id="_from2" uri="jgroups:mainCluster?enableViewMessages=true&amp;channelProperties=etc/jgroups.xml"/>
    <filter id="filterNonCoordinatorViews">
        <method ref="dropNonCoordinatorViews"/>
        <threads id="threads1" threadName="ControlThreads">
            <delay id="_delay1">
                <ref>delayIfContextNotStarted</ref>
                <log id="logCR" loggingLevel="INFO" message="Starting Main Cluster consumer!!!!!!!!!!!!!!!!!!!!!"/>
                <to id="_toCR" uri="controlbus:route?routeId=core.predix.tkndependencyCheckerRoute&amp;action=start&amp;async=true"/>
            </delay>
        </threads>
    </filter>
</route>
