Lab#13 Springboot Profiles

Springboot profiles are useful for different environments e.g dev, qa, prod

1. Add YAML Profile Files

Step #1 Add two more .yml files named as shown in the accounts microservice. Files are given.

Figure 1: Add YAML Files

2. application.yml spring.config

Step#2 Update the application.yml in the accounts microservice with the following spring.config properties.

      enabled: true
  jpa:
    database-platform: org.hibernate.dialect.H2Dialect
    hibernate:
      ddl-auto: update
    show-sql: true
  config:
    import:
      - "application_qa.yml"
      - "application_prod.yml"
build:
  version: "3.0"
accounts:
  message: "Welcome to accounts related local APIs"

3. Run App

Step#3 Run the application. You will see default profile is used by checking contact-info.

Figure 2: Default Profile

4. Profile Switching

Step#4 Update the application.yml to change the active profile to qa. Check the contact info again in Postman. Now you will see the information is read from the application_qa.yml

  config:
    import:
      - "application_qa.yml"
      - "application_prod.yml"
  profiles:
    active:
      - "qa"
build:
  version: "3.0"
accounts:
  message: "Welcome to accounts related local APIs"
