pom.xml中加上如下的配置,打包时jar包和lib依赖就会分离

     <build> 
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

                </configuration>
            </plugin>
 
            <plugin>
                <!--打包时去除第三方依赖-->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <layout>ZIP</layout>
                    <includes>
                        <include>

                            <artifactId>non-exists</artifactId>
                        </include>
                    </includes>
                </configuration>
            </plugin>
            <!--拷贝第三方依赖文件到指定目录-->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>

                        <phase>package</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <!--target/lib是依赖jar包的输出目录，根据自己喜好配置-->
                            <outputDirectory>target/lib</outputDirectory>
                            <excludeTransitive>false</excludeTransitive>
                            <stripVersion>false</stripVersion>
                            <includeScope>runtime</includeScope>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

但是项目启动时需要指定lib依赖

java -Dloader.path=lib包的路径(可以是相对路径),resources,lib -Dfile.encoding=utf-8 -jar xxx.jar
