To kill dev server you can simply press control-c as the docs state: 要杀死开发服务器，您只需在文档状态下按control-c即可：
To stop the web server, press Control-C (on Windows, Mac or Linux).
Control-c is in Unix systems sends the SIGINT signal, which you can achieve manually via kill -SIGINT <pid> . Control-c在Unix系统中发送SIGINT信号，您可以通过kill -SIGINT <pid>手动实现。
This should gracefully shutdown the server - in this case you can install a lifecycle listener to get called when server shuts down. 这应该可以正常关闭服务器-在这种情况下，您可以安装生命周期侦听器以在服务器关闭时被调用。 Just implement the contextDestroyed(..) method as shown in this example and register it in your web.xml . 只需实现本示例中所示的contextDestroyed(..)方法，然后将其注册到web.xml 。
NOTE: such shutdown hook does NOT work on production server (verified). 注意：这样的关闭挂钩在生产服务器（已验证）上不起作用。 I never tried it on dev server, but it should work as this is plain Jetty. 我从未在开发服务器上尝试过它，但是它应该可以正常工作，因为这是普通的Jetty。
