extShutdownHook Spring boot JAR 文件 AWS EC2 部署错误

Question

我现在正在制作基于 Spring Boot 的 Web 项目。

使用AWS EC2 ubuntu 进行部署时，出现未解决的错误，我想分享一下。

项目堆栈：Spring boot + AWS (EC2, S3, RDS(MariaDB)) 部署由 ubuntu 使用 Spring boot JAR 文件运行。 java -jar *.jar

问题是每当我通过 JAR 文件启动应用程序时，服务器会立即停止并显示此日志。我以为是因为 WebSocketConfig.java 用于聊天消息功能，但即使我添加了Threadpoooltaskschedule 和STOMP setAllowedOrigins，症状仍然存在。 自己解决很累，需要大家帮忙。

WebSocketConfig.java

private static final Logger LOGGER = LoggerFactory.getLogger(WebsocketBrokerConfig.class);

@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {

    //for subscribe prefix
    registry.enableSimpleBroker("/user");
    //for publish prefix
    registry.setApplicationDestinationPrefixes("/app");
    //user destination provides ability to have unique user queue
    //registry.setUserDestinationPrefix("/user");
    
}

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    
    registry.addEndpoint("/broadcast")
        .setAllowedOrigins("http://ec2....amazonaws.com")   
        .withSockJS()
        .setHeartbeatTime(60_000);
}

将 Spring BOOT 应用程序放在 EC2 实例上的最简单方法是使用 Elastic Beanstalk。阅读此 AWS 文档了解更多详细信息 - https://aws.amazon.com/blogs/devops/deploying-a-spring-boot-application-on-aws-using-aws-elastic-beanstalk/
