关闭 Apache ActiveMQ

Question

我正在运行带有嵌入式 ActiveMQ 服务器 (5.10.0) 的 Spring Boot (1.3.5) 控制台应用程序，它可以很好地接收消息。但是，我无法毫无例外地关闭应用程序。

在按下 Ctrl-C 后，每个队列都会抛出一次此异常：

2016-09-21 15:46:36.561 ERROR 18275 --- [update]] o.apache.activemq.broker.BrokerService   : Failed to start Apache ActiveMQ ([my-mq-server, null], {})

似乎 DefaultMessageListenerContainer 试图启动一个对我来说没有意义的 ActiveMQ 服务器。我已将 BrokerService 的阶段设置为 Integer.MAX_INT - 1 并将 DefaultJmsListeningContainerFactory 的阶段设置为 Integer.MAX_INT 以使其在 ActiveMQ 服务器停止之前消失。

我的 main() 中有这个：

public static void main(String[] args) {
    final ConfigurableApplicationContext context = SpringApplication.run(SiteServer.class, args);
    context.registerShutdownHook();
}

我已尝试按照此处的建议将 daemon 设置为 true：Properly Shutting Down ActiveMQ and Spring DefaultMessageListenerContainer。

有什么想法吗？谢谢！ =)

找到了。当 Camel 上下文在 BrokerService 之后 关闭时，会出现此问题。添加适当的生命周期管理，以便在解决问题之前关闭 Camel。现在一切都以干净的方式关闭，没有错误。
