The Hidden Assumptions in Spring Boot Defaults Costing You Performance
Spring Boot's "just works" philosophy is a double-edged sword. Developers love how quickly a project boots, but that magic comes from hidden defaults—assumptions that can quietly degrade your application's performance, security, or operational sanity. Think of auto-configuration as a well-meaning friend who sets up your kitchen, but you never check which utensils are sharp or what's lurking in the pantry. The defaults are sensible for demos, but production is a different beast. This article digs into those assumptions, showing you exactly what Spring Boot decides for you, where it hurts, and how to take back control without losing the magic. Who Pays for Spring Boot's Convenience? The developer's trade-off: speed vs. control Spring Boot sells you a promise: point at a dependency, add a few annotations, and your service is up before your coffee cools. That pitch is seductive.
