Lots of secret content like database passwords, OAuth secret keys, etc. should be hidden from the public repo.
For example, the database host, username and password in dop-server/application-server/src/main/resources/application-production.yml:

  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:mysql://172.29.7.157:3306/db_dop_application
    username: xxxxxxxxxxxx
    password: xxxxxxxxxxxx

and email secrets in message-server/src/main/resources/application-local.yml

  mail:
    host: smtp.qq.com
    username: [email protected]
    password: xxxxxxxxxxxxxx
