What is the difference between putting a property on application.yml or bootstrap.yml in spring boot?

What is the difference between putting a property on application.yml or bootstrap.yml in spring boot? In logging.config case, the application works differently.

Solution

  • I have just asked the Spring Cloud guys and thought I should share the info I have here.

    bootstrap.yml is loaded before application.yml.

    It is typically used for the following:

    • when using Spring Cloud Config Server, you should specify spring.application.name and spring.cloud.config.server.git.uri inside bootstrap.yml
    • some encryption/decryption information

    Technically, bootstrap.yml is loaded by a parent Spring ApplicationContext. That parent ApplicationContext is loaded before the one that uses application.yml.
