  mysql:
    image: mysql:5.7
    container_name: mysql
    restart: always
    ports:
      - 3306:3306
    volumes:
      - "/home/jim/project/dev_env/mysql/data:/var/lib/mysql"
      - "/home/jim/project/dev_env/mysql/conf:/etc/mysql"

    ports:
      - 8080:8080
    links:
      - mysql:mysql
    environment:
      - spring.profiles.active=dev

说明
- ./mvnw install dockerfile:build 生成镜像（生成jar包->解压->根据Dockerfile生成镜像）
- docker-compose.yml 中 swagger-service访问 mysql，需要设置links，在项目 application.yml 中设置数据库链接字符串为jdbc:mysql://mysql:3306/demo?characterEncoding=utf-8
- docker-compose up 启动mysql、swagger-service
- 第一次启动mysql时，需要初始化数据库数据（没有demo数据库），初始sql见github
