springboot中的yml配置

${DATASOURCE_PASSWORD:123456*} ，如果DATASOURCE_PASSWORD 没有值，默认123456*

server:
  tomcat:
    basedir: /home/temp
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    password: ${DATASOURCE_PASSWORD:123456*}
    username: ${DATASOURCE_USERNAME:root}
    url: ${DATASOURCE_URL:jdbc:mysql://localhost:3306/oauth2?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC}
  jpa:
    database: mysql
    hibernate:
      ddl-auto: update
logging:
  path: /logs

docker-compose.yml 配置（mysql+springdome）

    ports:
      - 3306:3306
    environment: 
       TZ: Asia/Shanghai
       MYSQL_ROOT_PASSWORD: 123456*
    volumes:
      - ./mysql/mysqld.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf
      - ./mysql/data:/var/lib/mysql
    networks:
      - my-network
  springdome:
    image: springdome:1.0
    restart: always
    container_name: springdome
    ports: 
      - "8081:8080"
    networks:
      - my-network
    volumes:
      - ./spring/tmp:/home/temp
      - ./spring/logs:/logs
    depends_on:
