配置插件不使用任何依赖

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <mainClass>cn.com.wenyl.bs.BSBootApplication</mainClass>  <!-- 你的主类 -->
                    <executable>true</executable>
                    <layout>NONE</layout>
                    <includes>
                        <include>
                            <groupId>nothing</groupId>
                            <artifactId>nothing</artifactId>
                        </include>
                    </includes>
                </configuration>
            </plugin>

依赖包分离处理

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <version>3.1.2</version>
                <executions>
                    <execution>
                        <id>copy-dependencies</id>
                        <phase>package</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>${project.build.directory}/lib</outputDirectory>
                            <includeScope>runtime</includeScope>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

打包好后目录下有jar包和lib目录

拷贝到服务器上执行启动命令

java -jar bs-boot-system-1.0-SNAPSHOT.jar -Dloader.path ./lib

这里-Dloader.path指向自己的lib目录即可
