Question

我现在已经使用过Camel几次，但这个问题已经过去了，我不知道我做错了什么。它是一个新应用程序，应从IBM MQ获取消息并将文件放入磁盘。路线很简单：

String fromString = "message-queue:XXX.FUNDORDER.YYY.OUT?testConnectionOnStartup=true";

    from(fromString)
        .autoStartup(true)
        .routeId("RouteReceiver")
        .log("Processing message ${exchangeId}")
        .to("file:/in?fileName=${exchangeId}.txt");

这是创建连接工厂时使用的代码：

public JmsConnectionFactory websphereConnectionFactory() throws JMSException
          {

    Logger logger = Logger.getLogger(Config.class);

    logger.info("ibmMqChannel = " + ibmMqChannel);
    logger.info("ibmMqHost = " + ibmMqHost);
    logger.info("ibmMqPort = " + ibmMqPort);
    logger.info("ibmMqQueueManagerName = " + ibmMqQueueManagerName);


    /*
     * Create MQConnectionFactory
     */
    final MQConnectionFactory connectionFactory = new MQConnectionFactory();
    connectionFactory.setHostName(ibmMqHost);
    connectionFactory.setPort(ibmMqPort);
    connectionFactory.setChannel(ibmMqChannel);
    connectionFactory.setQueueManager(ibmMqQueueManagerName);
    connectionFactory.setIntProperty(CommonConstants.WMQ_CONNECTION_MODE, CommonConstants.WMQ_CM_CLIENT);

    logger.debug("connectionFactory=" + connectionFactory.toString());

    /*
     * Add ConnectionFactory to JmsConfiguration
     */
    final JmsConfiguration jmsConfiguration = new JmsConfiguration();
    jmsConfiguration.setConnectionFactory(connectionFactory);

    /*
     * Add JmsConfiguration to JmsComponent
     */
    final JmsComponent jmsComponent = new JmsComponent();
    jmsComponent.setConfiguration(jmsConfiguration);
    jmsComponent.setAcknowledgementModeName("AUTO_ACKNOWLEDGE");

    /*
     * Add JmsComponent to camelContext
     */
    camelContext.addComponent("message-queue", jmsComponent);


    return connectionFactory;

}

在应用程序启动并测试连接后立即开始关闭。没有异常被抛出。在本地测试时，我使用不同的配置文件并连接到ActiveMQ服务器。这样可以正常运行。

非常感谢任何帮助！

您使用的是SpringBoot吗？如果是，您的应用程序是否可能无法阻止，因此只需在启动后关闭，因为主要方法已完成？

根据http://camel.apache.org/spring-boot.html，有许多方法可以阻止SpringBoot应用程序中的主线程（请参阅链接了解更多详细信息）：

您的路线类扩展了org.apache.camel.spring.boot.FatJarRouter类
使用CamelSpringBootApplicationController.blockMainThread()
在pom.xml

spring-boot-starter-web

在属性或YAML文件

camel.springboot.main-run-controller

true

成功进行测试连接后，立即关闭到IBM MQ的Camel jms路由
