创建一个名为your-app的脚本。服务(rest-app.service)。 我们应该把这个脚本放在/etc/systemd/system目录下。 下面是脚本的示例内容

[Unit]
Description=Spring Boot REST Application
After=syslog.target

[Service]
User=javadevjournal
ExecStart=/var/rest-app/restdemo.jar
SuccessExitStatus=200

[Install]
WantedBy=multi-user.target

下一个:

 service rest-app start

Following up on Chad's excellent answer, if you get an error of "Error: Could not find or load main class" - and you spend a couple hours trying to troubleshoot it, whether your executing a shell script that starts your java app or starting it from systemd itself - and you know your classpath is 100% correct, e.g. manually running the shell script works as well as running what you have in systemd execstart. Be sure you're running things as the correct user! In my case, I had tried different users, after quite a while of troubleshooting - i finally had a hunch, put root as the user - voila, the app started correctly. After determining it was a wrong user issue, I chown -R user:user the folder and subfolders and the app ran correctly as the specified user and group so no longer needed to run it as root (bad security).

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>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

下面是一个脚本，它将可执行jar部署为systemd服务。

它为服务和.service文件创建一个用户，并将jar文件放在/var下，并对特权进行一些基本的锁定。

#!/bin/bash

# Argument: The jar file to deploy
APPSRCPATH=$1

# Argument: application name, no spaces please, used as folder name under /var
APPNAME=$2

# Argument: the user to use when running the application, may exist, created if not exists
APPUSER=$3

# Help text
USAGE="
Usage: sudo $0 <jar-file> <app-name> <runtime-user>
If an app with the name <app-name> already exist, it is stopped and deleted.
If the <runtime-user> does not already exist, it is created.
"

# Check that we are root
if [ ! "root" = "$(whoami)" ]; then
    echo "Must be root. Please use e.g. sudo"
    echo "$USAGE"
    exit
fi

# Check arguments
if [ "$#" -ne 3 -o ${#APPSRCPATH} = 0 -o ${#APPNAME} = 0 -o ${#APPUSER} = 0 ]; then
    echo "Incorrect number of parameters."
    echo "$USAGE"
    exit
fi

if [ ! -f $APPSRCPATH ]; then
    echo "Can't find jar file $APPSRCPATH"
    echo "$USAGE"
    exit
fi

# Infered values
APPFILENAME=$(basename $APPSRCPATH)
APPFOLDER=/var/javaapps/$APPNAME
APPDESTPATH=$APPFOLDER/$APPFILENAME

# Stop the service if it already exist and is running
systemctl stop $APPNAME >/dev/null 2>&1

# Create the app folder, deleting any previous content
rm -fr $APPFOLDER
mkdir -p $APPFOLDER

# Create the user if it does not exist
if id "$APPUSER" >/dev/null 2>&1; then
    echo "Using existing user $APPUSER"
else
    adduser --disabled-password --gecos "" $APPUSER
    echo "Created user $APPUSER"
fi

# Place app in app folder, setting owner and rights
cp $APPSRCPATH $APPDESTPATH
chown $APPUSER $APPDESTPATH
chmod 500 $APPDESTPATH
echo "Added or updated the $APPDESTPATH file"

# Create the .service file used by systemd
echo "
[Unit]
Description=$APPNAME
After=syslog.target
[Service]
User=$APPUSER
ExecStart=/usr/bin/java -jar $APPDESTPATH
SuccessExitStatus=143
[Install]
WantedBy=multi-user.target
" > /etc/systemd/system/$APPNAME.service
echo "Created the /etc/systemd/system/$APPNAME.service file"

# Reload the daemon
systemctl daemon-reload

# Start the deployed app
systemctl start $APPNAME
systemctl status $APPNAME

例子:

在这个问题中，@PbxMan的回答可以让你开始:

在Linux上运行Java应用程序作为服务

编辑:

还有另一种不太好的方式在重启时启动进程，使用cron:

@reboot user-to-run-under /usr/bin/java -jar /path/to/application.jar

这是可行的，但不能为应用程序提供良好的启动/停止界面。你仍然可以简单地杀死它……

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
