@ConfigurationProperties

Reference: Spring Docs - @ConfigurationProperties

• An annotation that retrieves and binds property values from *.properties or *.yml files to Java classes

• Using this annotation automatically handles binding for various notation styles

  • ex)

    acme.my-project.person.first-name	Recommended notation for properties and .yml
    acme.myProject.person.firstName	Standard camel case syntax.
    acme.my_project.person.first_name	Notation usable in .properties and .yml (dash notation is more standard)
    ACME_MYPROJECT_PERSON_FIRSTNAME	Recommended when using system environment variables

• The property file must be registered as a Bean for it to work properly
