我使用mvn clean包构建它并获取一个xxx.jar文件.
运行$java -jar xxx.jar>> output.log&启动它,它运作良好.

但大约两个小时后,它关机,为什么？
这是一个答案,但不适合我>> https://stackoverflow.com/a/22409655/1767024

这是我的output.log：

解决方法:

改为运行您的应用程序：

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

从Wikipedia开始：

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.

从Linux man pages开始：

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

此外,如果您只是添加Web服务器以保持应用程序活动并且实际上不使用它,请考虑使用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();
}

现在要停止应用程序,您可以从控制台查找进程ID并发出kill命令：

kill <PID>
