这里涉及两个打包插件

maven-dependency-plugin和spring-boot-maven-plugin
将依赖放置单独的文件夹

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<plugin>        <groupId>org.apache.maven.plugins</groupId>        <artifactId>maven-dependency-plugin</artifactId>        <version>3.1.2</version> <!-- 请根据需要使用适当的版本 -->        <executions>          <execution>            <id>copy-dependencies</id>            <phase>prepare-package</phase>            <goals>              <goal>copy-dependencies</goal>            </goals>            <configuration>              <outputDirectory>${project.build.directory}/lib</outputDirectory>            </configuration>          </execution>        </executions>      </plugin>

　　精简jar体积

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

<plugin>        <configuration>          <includeSystemScope>true</includeSystemScope>        </configuration>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-maven-plugin</artifactId>        <version>${spring-boot.version}</version>        <executions>          <execution>              <id>repackage</id>              <configuration>                <skip>true</skip>              </configuration>          </execution>        </executions>      </plugin>

　　

 

 

 

 这里的启动命令需要调整

?

1	java -cp "a.jar;lib/*" com.java.Application

　　

?

1	其中com.java.Application为启动类的路径
