Question

我创建了多个camelContexts，并希望每个camelContext都使用自己的自定义线程池。但是，日志显示我所有的camelContexts都使用相同的线程池。我错过了什么？

主要骆驼背景

<camelContext id="routeLoader_route">
    (no threadpool defined)

    <route id="RouteCreator" >
        <from uri="file://jsonFilePath" />
        <bean ref="routeMonitor" method="loadJsontoCreateRoute" />
    </route>

    (some other routes defined)
</camelContext>

方法“loadJsontoCreateRoute”将读取三个json文件，然后创建三个连接路由

端点“file：// xxx1 / out”到端点“direct-vm：out.test”
端点“file：// xxx2 / out”到端点“direct-vm：out.test”
端点“file：// xxx3 / out”到端点“direct-vm：out.test”

另一个骆驼情境

<camelContext id="test_out_route">
    <threadPoolProfile id="outTestThreadPoolProfile" defaultProfile="true" poolSize="1" maxPoolSize="1" maxQueueSize="1000"  rejectedPolicy="CallerRuns"/>

    <route id="outboundTestingRouter">
        <from uri="direct-vm:out.test"/>
        <doTry>
            <log message="Outbound Test -- START" loggingLevel="INFO" />
            <recipientList>
                <method ref="outTestBean" method="dynamicRoute" />
            </recipientList>
        <doFinally>
            <log message="Outbound Test-- END" loggingLevel="INFO" />
            <stop/>
        </doFinally>
        </doTry>
    </route>

    (Some other routes defined)
</camelContext>

dynamicRoute方法将返回up for ftp component

日志的第3行到第10行显示，当我的threadpool outTestThreadPoolProfile池大小限制为1时，有多个outboundTestingRouter路由同时运行

这表明脱口使用了线程池outTestThreadPoolProfile并没有被outboundTestingRouter路由使用

我想要的是限制最大值。 route outboundTestingRouter的并发使用次数。

嗯，看起来应该有用。日志声明怎么说你没有使用你的线程池？

注意事项：

1）您的路由需要利用线程池来取消默认模板。

2）您始终可以手动将线程池分配给组件，语法类似于：executorServiceRef =＆＃34; outTestThreadPoolProfile＆＃34;但请务必查看您的组件文档

3）如果您的默认线程池配置文件不起作用，您可以简单地使用标准ThreadPool标记创建一个可以直接分配给组件的隔离线程池。
