1、在父工程的pom文件中统一指定jdk版本，还有springboot的版本，本例子使用jdk11，jdk8也是可以的
<properties>
<!--docker镜像仓库的前缀-->
<docker.image.prefix>kimhank</docker.image.prefix>
</properties>
<build>
<!--jar包的名称-->
<finalName>order-service</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>

<configuration>

<!--构建docker镜像的插件-->
<plugin>
<!--Spotify 的 docker-maven-plugin 插件是?于构建docker镜像的-->
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>1.4.10</version>
<configuration>
<!--docker仓库-->
<repository>${docker.image.prefix}/${project.artifactId}-16</repository>
<buildArgs>
<!--jar包位置-->
<JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
</buildArgs>
</configuration>
</plugin>
</plugins>
</build>
FROM adoptopenjdk/openjdk11:ubi VOLUME /tmp ARG JAR_FILE COPY ${JAR_FILE} app.jar ENTRYPOINT ["java","-jar","/app.jar","-Xms128M","-Xmx128M"]
vim /etc/profile
编辑环境变量。。。
source /etc/profile
mvn clean && mvn install
mvn install -Dmaven.test.skip=true dockerfile:build
大功告成了，执行 docker images 查看镜像
