如何以正确的方式关闭Spring Boot应用程序? [英] How to shutdown a Spring Boot Application in a correct way?
问题描述
在Spring Boot文档中，他们说:每个SpringApplication都将向JVM注册一个关闭钩子，以确保ApplicationContext在退出时正常关闭."
In the Spring Boot Document, they said that 'Each SpringApplication will register a shutdown hook with the JVM to ensure that the ApplicationContext is closed gracefully on exit.'
当我在shell命令上单击ctrl+c时，可以正常关闭该应用程序.如果我在生产机器上运行该应用程序，则必须使用以下命令
java -jar ProApplicaton.jar.但是我无法关闭shell终端，否则它将关闭进程.
When I click ctrl+c on the shell command, the application can be shutdown gracefully. If I run the application in a production machine, I have to use the command
java -jar ProApplicaton.jar. But I can't close the shell terminal, otherwise it will close the process.
如果我运行nohup java -jar ProApplicaton.jar &之类的命令，则无法使用ctrl+c正常关闭它.
If I run command like nohup java -jar ProApplicaton.jar &, I can't use ctrl+c to shutdown it gracefully.
在生产环境中启动和停止Spring Boot Application的正确方法是什么?

推荐答案
如果使用执行器模块，则可以通过JMX或HTTP如果启用了端点，则可以关闭应用程序(将endpoints.shutdown.enabled=true添加到application.properties文件).
If you are using the actuator module, you can shutdown the application via JMX or HTTP if the endpoint is enabled (add endpoints.shutdown.enabled=true to your application.properties file).
/shutdown-允许正常关闭应用程序(默认情况下未启用).
/shutdown - Allows the application to be gracefully shutdown (not enabled by default).
取决于端点公开的方式，敏感参数可以用作安全提示.例如，通过HTTP访问敏感端点时，它们将需要用户名/密码(如果未启用Web安全，则将其禁用).
Depending on how an endpoint is exposed, the sensitive parameter may be used as a security hint. For example, sensitive endpoints will require a username/password when they are accessed over HTTP (or simply disabled if web security is not enabled).
