Spring Boot 3.0, released in November 2022, wasn’t just a minor update; it was a paradigm shift for Java development. This major upgrade boasts a plethora of new features, performance optimizations, and foundational changes that catapulted Spring Boot to a whole new level. Let’s delve deeper into the key highlights and explore their implications in detail:

Java 17 Baseline:

What it means: Spring Boot 3.0 requires Java 17 or higher. This isn’t just a formality; it unlocks a treasure trove of benefits:

Improved performance: Java 17 introduces Switch expressions with sealed classes, allowing for concise and efficient control flow. Additionally, improved garbage collection algorithms and optimizations lead to faster startup times and better memory management.

Enhanced null safety: With records and non-null assertions, you can write code with more confidence, reducing the risk of null pointer exceptions. No more null checks cluttering your code!

Modern features: Records bring a functional and concise way to define data structures, while pattern matching enhances readability and maintainability.

Benefits: You’ll experience faster, more reliable, and modern applications without writing a single line…
