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 都会向 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命令上点击ctrl+c时，应用程序可以正常关闭.如果我在生产机器上运行应用程序，我必须使用命令java -jar ProApplicton.jar.但是我不能关闭shell终端，否则会关闭进程.

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.

如果我运行像 nohup java -jar ProApplicaton.jar & 这样的命令，我就不能使用 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 应用程序的正确方法是什么?

What is the correct way to start and stop a Spring Boot Application in the production environment?

推荐答案

如果您正在使用执行器模块，您可以通过 JMX 或 HTTP 关闭应用程序，如果端点已启用.

If you are using the actuator module, you can shutdown the application via JMX or HTTP if the endpoint is enabled.

添加到application.properties:

endpoints.shutdown.enabled=true

endpoints.shutdown.enabled=true

以下网址将可用:

/actuator/shutdown - 允许应用正常关闭(默认不启用).

/actuator/shutdown - Allows the application to be gracefully shutdown (not enabled by default).

根据端点的公开方式，敏感参数可用作安全提示.

Depending on how an endpoint is exposed, the sensitive parameter may be used as a security hint.

例如，敏感端点在通过 HTTP 访问时将需要用户名/密码(如果未启用网络安全，则直接禁用).

For example, sensitive endpoints will require a username/password when they are accessed over HTTP (or simply disabled if web security is not enabled).
