spring boot 应用程序在 ec2 上自动关闭
springboot application shutsdown automatically on ec2
我在 ec2 上部署了我的 springboot 应用程序
（ubuntu 为 t2.medium 大小，AWS AMI 为 t3.medium 大小）
在我的本地电脑上，没有问题..
但是在 ec2 上，几个小时后（在我不工作期间）
它自己死了
我只是想检查关机时发生了什么，所以我在下面 java class 作为 ContextClosedHandler.. 但它似乎对我没有帮助
@Component
public class ContextClosedHandler implements ApplicationListener<ContextClosedEvent> {
@Override
public void onApplicationEvent(ContextClosedEvent event) {
LOGGER.info(event.getSource());
LOGGER.info(event.getApplicationContext().getApplicationName());
LOGGER.info(event.getApplicationContext().getDisplayName());
LOGGER.info(event.getApplicationContext().getId());
LOGGER.info(event.getApplicationContext().getParent());
LOGGER.info(event.getApplicationContext().getStartupDate());
}
}

问题不在于应用程序自行关闭，而是有人试图通过发送伪造的请求来查找您应用程序的安全漏洞。您可以尝试通过 Web 服务器（如 Apache Httpd）过滤请求，然后再将它们转发到 Spring 启动应用程序来解决它。
它自动关闭的原因是在 shell.
上注销 ssh 会话
所以，我只是用 nohup 命令执行我的应用程序作为后台执行。
nohup java -jar my-application.jar &
如果我使用 docker 部署它，则没有问题。
