Question

以下是我的camel路由，用于发送定期消息并将队列中的消息转发到端点。

活动路线：

from("activemq:Queue.External?cacheLevelName=CACHE_CONSUMER&transacted=true")
            .routeId("EventRoute")
            .autoStartup(false)
            .filter(messageFilter)
            .process(eventTransformer)
            .setHeader(Exchange.HTTP_METHOD, constant(HttpMethods.POST))
            .setHeader(Exchange.ACCEPT_CONTENT_TYPE, constant("application/xml"))
            .setProperty("eventEndpoint", constant(eventEndpoint))
            .to(eventUri)
            .process(eventResponse);

定期消息路由：

from("timer:monitor?fixedRate=true&period=" + (periodicMessageInterval() * 1000))
            .routeId("periodicMessageRoute")
            .autoStartup(false)
            .process(periodicMessageTransformer)
            .setHeader(Exchange.HTTP_METHOD, constant(HttpMethods.POST))
            .setHeader(Exchange.ACCEPT_CONTENT_TYPE, constant("application/xml"))
            .doTry()
            .to(periodicMessageUri)
            .process(periodicMessageResponse)
            .doCatch(Exception.class)
            .log(LoggingLevel.DEBUG, "Error response received: ${body}");

定期消息检测的路由初始化

builder.from("activemq:topic:Topic.Heartbeat?concurrentConsumers=1&maxConcurrentConsumers=1")
            .routeId("periodic")
            .log(LoggingLevel.DEBUG, "Periodic Message Received: ${id}")
            .process(this);

    builder.from("timer:monitor?fixedRate=true&period=" + monitoringIntervalInMilliseconds)
            .routeId("timer")
            .log(LoggingLevel.DEBUG, "Checking periodic message reception")
            .process(exchange -> exchange.getIn().setBody(check()))
            .choice().when(builder.body(Boolean.class)).to("direct:stopActiveMqRoutes")
            .otherwise().to("direct:startActiveMqRoutes").end();


    ProcessorDefinition routeDefinitionStop = builder.from("direct:stopActiveMqRoutes");
    for (final String routeId : routeIds) {
        routeDefinitionStop = routeDefinitionStop
                .to("controlbus:route?routeId=" + routeId + "&action=status")
                .choice().when(builder.body().isNotEqualTo("Stopped"))
                .log(LoggingLevel.INFO, "Stopping route execution: " + routeId)
                .to("controlbus:route?routeId=" + routeId + "&action=stop&async=true")
                .end();
    }
    routeDefinitionStop.end();

    ProcessorDefinition routeDefinitionStart = builder.from("direct:startActiveMqRoutes");
    for (final String routeId : routeIds) {
        routeDefinitionStart = routeDefinitionStart
                .to("controlbus:route?routeId=" + routeId + "&action=status")
                .choice().when(builder.body().isNotEqualTo("Started"))
                .log(LoggingLevel.INFO, "Starting route execution: " + routeId)
                .to("controlbus:route?routeId=" + routeId + "&action=start&async=true")
                .end();
    }
    routeDefinitionStart.end();

两条路线在白天停电1小时后停止，路线在1小时后自动开始。是不是因为JDK中的Timer组件导致了这个问题？
