1、不瘦身之前打的jar包 :

maven -> package …17M
17M

2、在pom.xml中加入一下配置,重新打jar包

<build>
        <finalName>study-server</finalName>
        <plugins>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <classpathPrefix>lib/</classpathPrefix>
                            <mainClass>com.example.springbootdemo.SpringbootDemoApplication</mainClass>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id>copy-dependencies</id>
                        <phase>prepare-package</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>${project.build.directory}/lib</outputDirectory>
                            <overWriteReleases>false</overWriteReleases>
                            <overWriteSnapshots>false</overWriteSnapshots>
                            <overWriteIfNewer>true</overWriteIfNewer>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <includeSystemScope>true</includeSystemScope>
                    <executable>true</executable>
                    <mainClass>com.example.springbootdemo.SpringbootDemoApplication</mainClass>
                    <layout>ZIP</layout>
                    <includes>
                        <include>
                            <groupId>nothing</groupId>
                            <artifactId>nothing</artifactId>
                        </include>
                    </includes>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

        </plugins>
    </build>

瘦身plugin-><artifactId>spring-boot-maven-plugin</artifactId>(可以看出j瘦身后的jar包172k)
172k
<artifactId>maven-dependency-plugin</artifactId>plugin作用是lib下的jar
打出lib包lib

3、启动

study-server.jarlib文件夹放同一目录
study-server.jar
启动命令 :

nohup java -Dloader.path=./lib -jar study-server.jar >> console.log &

正常启动截图 :
启动成功
