1.增加打包插件

  <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>
        <finalName>${project.name}</finalName>
        <plugins>
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>dockerfile-maven-plugin</artifactId>
                <version>1.4.13</version>
                <executions>
                    <execution>
                        <id>default</id>
                        <goals>
                            <!--如果package时不想用docker打包,就注释掉这个goal
                            <goal>build</goal>
                            <goal>push</goal>-->
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <!-- 上下文路径配置，此处设置为项目根路径 用来读取Dockerfile-->
                    <contextDirectory>${project.basedir}</contextDirectory>
                    <!--使用Maven的setting.xml来配置账号密码-->
                    <useMavenSettingsForAuth>true</useMavenSettingsForAuth>
                    <!--上传路径/镜像构建名： Harbor地址/Harbor项目名/springboot项目名-->
                    <repository>${docker.registry.url}/${docker.namespace}/${project.artifactId}</repository>
                    <!-- 标签,最终会显示在Harbor镜像的标签中 -->
                    <tag>${project.version}</tag>
                    <!-- 作为Dockerfile 文件传入,也就是Dockerfile 中 ARG JAR_FILE的值-->
                    <buildArgs>
                        <JAR_FILE>${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                </configuration>
            </plugin>
        </plugins>
    </build>

2maven私服增加harbor仓库

    <!-- docker仓库地址 -->
    <server> 
        <id>harbor.xl686.com</id> 
        <username>admin</username> 
        <password>xxxxx</password> 
        <configuration> 
            <email>xxxx</email> 
        </configuration> 
    </server>
