如何在camel组件代码中防止jvm退出

public class MyCamelApp {
    public static void main(String[] args) throws Exception {
        Main main = new Main();
        // 添加Camel路由
        main.addRouteBuilder(new MyRouteBuilder());
        // 启动Camel应用程序
        main.run();
        // 防止JVM退出
        main.keepAlive();
    }
}

public class MyCamelApp {
    public static void main(String[] args) throws Exception {
        CamelContext context = new DefaultCamelContext();
        // 配置ShutdownStrategy
        context.getShutdownStrategy().setShutdownRoutesInReverseOrder(true);
        context.getShutdownStrategy().setTimeout(60);
        // 添加Camel路由
        context.addRoutes(new MyRouteBuilder());
        // 启动Camel应用程序
        context.start();
        // 防止JVM退出
        Thread.sleep(Long.MAX_VALUE);
    }
}

public class MyCamelApp {
    public static void main(String[] args) throws Exception {
        CamelContext context = new DefaultCamelContext();
        // 添加ControlBus组件
        context.addComponent("controlBus", new ControlBusComponent(context));
        // 添加Camel路由
        context.addRoutes(new MyRouteBuilder());
        // 启动Camel应用程序
        context.start();
        // 防止JVM退出
        ProducerTemplate template = context.createProducerTemplate();
        template.sendBody("controlBus:route?routeId=myRoute&action=start");
        Thread.sleep(Long.MAX_VALUE);
    }
}
