Java 在Spring应用程序关闭时发送RabbitMQ消息

我有一个监视服务，它在应用程序启动、应用程序关闭和每分钟（勾选）时向rabbitMQ发送一条消息

启动和勾选事件工作正常。 最初编写类时，关闭事件也起作用

我使用的是spring boot starter amqp 1.3.3.0版本

事件是在

DisposableBean

接口的

destroy

方法上触发的

我还尝试实现了

ApplicationListener

接口和

生命周期

接口

上述两种方法都返回：

java.lang.IllegalStateException:ApplicationContext已关闭且 ConnectionFactory无法再创建连接

我注意到有一个bug修复建议使用

生命周期

接口

如何确保在RabbitMQ连接关闭之前发送关机事件消息

编辑：更多信息和最新代码

应用程序有多个到不同服务器的连接工厂。监视器服务通过

monitorRabbitTemplate

连接到RabbitMQ服务器

问题似乎是

monitorRabbitTemplate

连接工厂在

MonitorService

之前获取生命周期/关闭/处置事件

最新代码（使用

Lifecycle

而不是

ApplicationListener

和

DisposableBean

）：

---

也许你可以分享一些代码/构建配置？因为听

ContextClosedEvent

和实现

Lifecycle

都对我有用

这是我的申请表：

@SpringBootApplication
public class SpringRabbitmqDemoApplication {

    @Component
    public static class Whatever implements Lifecycle {
        private final RabbitTemplate template;

        @Autowired
        public Whatever(RabbitTemplate template) {
            this.template = template;
        }

        @EventListener
        public void event(ContextClosedEvent event) throws Exception {
            sendMessage(event.toString());
        }

        private void sendMessage(String message) {
            template.convertAndSend("", "queue", message);
            System.out.println("Sent event " + message);
        }

        @Override
        public void start() {
            sendMessage("start");
        }

        @Override
        public void stop() {
            sendMessage("stop");
        }

        @Override
        public boolean isRunning() {
            return true;
        }
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringRabbitmqDemoApplication.class, args);
    }
}
