我在 ec2 上部署了 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
我只是想检查关闭时发生了什么，所以我制作了一个下面的 java 类作为 ContextClosedHandler.. 但这似乎对我没有帮助
@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());
}
}
日志如下所示

它自动关闭的原因是注销 shell 上的 ssh 会话。
所以，我刚刚执行了我的应用程序nohup作为后台执行的命令。
nohup java -jar my-application.jar &
如果我使用 docker 部署它，就没有问题。
