我已经用过几次骆驼了，但这个问题已经超出了我的想象，我不知道我做错了什么。它是一个新应用程序，应该从 IBM MQ 获取消息并将文件放置到磁盘。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");

以下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，它立即开始关闭。不抛出异常。在本地测试时，我使用不同的配置文件并连接到 ActiveMQ 服务器。这运行良好，并做了它应该做的事情。

任何帮助将不胜感激！

你在使用 SpringBoot 吗？如果是，您的应用程序是否可能不会阻塞，因此在启动后只是因为 main 方法完成而关闭？

根据http://camel.apache.org/spring-boot.html有很多方法可以阻止 SpringBoot 应用程序中的主线程（有关详细信息，请参阅链接）：

  • 您的路线类扩展了org.apache.camel.spring.boot.FatJarRouter类
  • 利用CamelSpringBootApplicationController.blockMainThread()
  • spring-boot-starter-web在 pom.xml 中包含依赖项
  • 在属性或 YAML 文件中camel.springboot.main-run-controller设置属性true
