Enterprise Java Configuration with Spring Boot

Configuring enterprise applications correctly is the difference between a secure, scalable system and a fragile deployment. This course teaches you how to manage application settings safely and efficiently using Spring Boot's powerful configuration APIs. You will transition from hardcoded values to flexible, production-ready external configuration patterns. What you'll learn: Understand core configuration concepts and the Spring property resolution lifecycle; Manage application settings using application.properties and YAML files; Override default values dynamically using system environment variables; Secure sensitive credentials by integrating password managers and external secret stores; Apply modern profiles to separate development, testing, and production environments; Write clean configuration properties classes with modern Java type hints and validation. We begin with foundational concepts of externalized configuration before moving step-by-step into advanced overriding mechanisms and security integration. This text-based course is designed for Java developers who are new to Spring Boot configuration and want to build secure, production-grade applications.
