springboot项目中使用maven resources
maven resource 组件可以把pom的变量替换到相关的resouces目录中的资源文件变量
示例项目：内容中心 （文章管理） 生成jar包，生成docker ，生成k8s文件

3.5 resources目录
3.5.1 resources/dev/docker/Dockerfile
FROM dockerimage.mysite.com/java/alpine-oraclejdk8:8.131.11-slim
VOLUME /tmp
ADD @project.build.finalName@.jar app.jar
RUN sh -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"
3.5.2 resource/dev/k8s/rc 及 resources/dev/k8s/svc
1) rc文件
apiVersion: v1
kind: ReplicationController
metadata:
name: @project.artifactId@
spec:
replicas: 1
selector:
name: @project.artifactId@
template:
metadata:
labels:
name: @project.artifactId@
spec:
containers:
- name: api
image: dockerimage.mysite.com/@app-name@/@app-name@
ports:

2）svc文件
apiVersion: v1
kind: Service
metadata:
name: @app-name@ #也可替换为 @project.artifactId@
spec:
selector:

3.6 application.yml文件

hystrix:

trackerList: #TrackerList参数,支持多个
- @app-dfs1@

3.7 resource/pro文件夹与dev文件夹文件相似，只是个别配置不同。
4.重要总结
4.1 在pom文件中，引用maven变量使用 ${变量名}即可
4.2 在springboot项目中，使用maven resources组件时，使用@变量名@ 进行取值(因为springboot项目中进行了特殊处理）
4.3 在使用maven resources组件时
<excludes>
<exclude>dev/**</exclude>
<exclude>pro/**</exclude>
</excludes> * 匹配 0或N个字符
** 匹配 0或N个目录
如果使用*不能实现相应功能，请切换** 即可
4.4 在使用maven resources组件时，只要增加了resource这个节点，必须重新指定resources文件夹位置
