如何在Linux系统中将Spring Boot应用程序打包为可执行jar as a Service ?这是推荐的方法吗，还是应该将这个应用程序转换为war并将其安装到Tomcat中?
目前，我可以从屏幕会话运行Spring引导应用程序，这很好，但需要在服务器重新启动后手动启动。
我正在寻找的是一般的建议/方向或样本init。D脚本，如果我的方法与可执行jar是适当的。

作为Windows服务
如果你想在windows机器上运行，请下载winsw.exe
http://repo.jenkins-ci.org/releases/com/sun/winsw/winsw/2.1.2/
之后，将其重命名为jar文件名(例如:your-app.jar)
winsw.exe -> your-app.exe
现在创建一个xml文件your-app.xml，并将以下内容复制到该文件中
<?xml version="1.0" encoding="UTF-8"?>
<service>
<id>your-app</id>
<name>your-app</name>
<description>your-app as a Windows Service</description>
<executable>java</executable>
<arguments>-jar "your-app.jar"</arguments>
<logmode>rotate</logmode>
</service>
确保exe和xml以及jar文件在同一个文件夹中。
在此之后，在管理员权限下打开命令提示符并将其安装到windows服务。
your-app.exe install
eg -> D:\Springboot\your-app.exe install
如果失败了
Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion' has value '1.8', but '1.7' is required.
然后试试下面的方法:
Delete java.exe, javaw.exe and javaws.exe from C:\Windows\System32
就是这样:).
在windows下卸载服务
your-app.exe uninstall
查看/运行/停止服务: win+r并输入Administrative tools，然后从中选择服务。然后右击选择选项-运行/停止
您正在使用Maven吗?那么你应该试试AppAssembler插件:
Application Assembler Plugin是一个Maven插件，用于生成启动java应用程序的脚本. ...所有工件(依赖项+项目中的工件)都被添加到生成的bin脚本中的类路径中。 支持平台: unix变体 Windows NT(不支持Windows 9x) Java服务包装器(JSW)

对于SpringBoot 2.4.4，除了由 @ismael
我在maven pom.xml中有以下内容，使其成为可执行jar
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<executable>true</executable>
</configuration>
<executions>

我最终为WAR/JAR布局做了systemd服务
我调用java -jar是因为它更灵活。我还试着把ExecStart=spring-mvc。战争，但即使是可执行的，我得到'Exec格式错误'
无论如何，现在systemd出现在所有发行版上，并提供了一个很好的解决方案来重定向日志(syserr是重要的，当你的服务甚至没有启动log4j文件位置将为空:))。
