• Many sources can set one property; Boot defines an order, highest priority first (summary).
• Command-line arguments beat environment variables, which beat profile files, which beat the base application.yml.

• Environment variable SHOP_TAXRATE or SHOP_TAX_RATE maps to shop.tax-rate by relaxed binding.
• Secrets belong in the environment or a secret store, never in committed YAML. Verify the full order in the docs for your version.
