java - 为什么spring boot总是两小时后关机

Question

我使用 mvn clean package 构建它并获得一个 xxx.jar 文件。 运行 $java -jar xxx.jar >> output.log & 启动它，它运行良好。

但是大约两个小时后，它就关机了，为什么？这是一个答案，但对我不起作用 >> https://stackoverflow.com/a/22409655/1767024

这是我的输出日志:

Answer 1

改为按如下方式运行您的应用程序:

nohup java -jar xxx.jar > output.log 2>&1&

来自 Wikipedia :

nohup is a POSIX command to ignore the HUP (hangup) signal. The HUP signal is, by convention, the way a terminal warns dependent processes of logout. Output that would normally go to the terminal goes to a file called nohup.out if it has not already been redirected.

来自Linux man pages :

nohup - run a command immune to hangups, with output to a non-tty

此外，如果您只是添加 Web 服务器以保持您的应用程序处于 Activity 状态而不实际使用它，请考虑改用 CountDownLatch:

@Bean
public CountDownLatch closeLatch() {
    return new CountDownLatch(1);
}

public static void main(String... args) throws InterruptedException {
    ApplicationContext ctx = SpringApplication.run(MyApp.class, args); 

    final CountDownLatch closeLatch = ctx.getBean(CountDownLatch.class);
    Runtime.getRuntime().addShutdownHook(new Thread() {
        @Override
        public void run() {
            closeLatch.countDown();
        }
    }); 
    closeLatch.await();
}

现在要停止您的应用程序，您可以查找进程 ID 并从控制台发出 kill 命令:

kill <PID>
