阿帕奇骆驼Quartz2

Question

我试图使用Apache Camel Quartz2实现一个调度器，它每分钟执行一次路由，并按预期执行一些任务。我使用spring DSL实现与apache camel相关联的路由，如下所示：

<camelContext
        xmlns="http://camel.apache.org/schema/spring">
        <propertyPlaceholder id="properties"
            location="classpath:application.properties" />
        <route>
            <from uri="quartz2://spring?cron=0+*+*+?+*+*" />
            <multicast parallelProcessing="true">
                <to uri="direct:DomainsWithFTPUsers" />
                <to uri="direct:DomainsWithoutFTPUsers" />
            </multicast>

根据日志，它不会记录为路由记录的消息，例如Direct:DomainsWithFTPUsers等等。请指导如何实现同样的目标。

Answer 1

根据克劳斯的建议，我对我的主要方法做了以下修改，现在它正像预期的那样工作。之前，我使用下面的代码初始化上下文并启动路由，因此JVM停止了它的执行：

public static void main(String[] args) throws Exception {
        ApplicationContext appContext = new ClassPathXmlApplicationContext(
                "applicationContext.xml");
        CamelContext camelContext = SpringCamelContext.springCamelContext(
                appContext, false);
    }

修正了保持JVM运行的方法：

public static void main(String[] args) throws Exception {
    Main main = new Main();
    main.enableHangupSupport();
    main.setFileApplicationContextUri("classpath:applicationContext.xml");
    main.run();
}
