Spring Boot 4 New Feature: Null Safety with JSpecify (No More NPE!)

NullPointerException is one of the most common and dangerous problems in Java applications. In this video, we explore a MAJOR improvement introduced in Spring Boot 4 (via Spring Framework 7) — standardized null safety using JSpecify. You will learn: ✔ What was wrong with null handling before Spring Boot 4 ✔ What exactly changed in Spring Boot 4 ✔ New null-safety annotations like @NullMarked, @Nullable, @NonNull, @NullUnmarked ✔ How Spring Boot 4 prevents null bugs at compile time ✔ How Error Prone + NullAway enforce null safety ✔ Why this is NOT possible in Spring Boot 3 ✔ Real examples that fail the build before runtime This video is perfect for: • Java Developers • Spring Boot Developers • Beginners learning Spring Boot 4 • Developers migrating from Spring Boot 3 to 4 Spring Boot 4 does not magically remove NullPointerException — it prevents developers from writing unsafe null code. 📌 Topics Covered: 00:00 Introduction 01:00 Null problem before Spring Boot 4 03:00 What is JSpecify 05:00 @NullMarked explained 07:00 @Nullable vs @NonNull 09:00 Compile-time enforcement 11:00 Maven configuration explained 13:00 Conclusion 👍 Like | 💬 Comment | 🔔 Subscribe for more Spring Boot 4 tutorials #SpringBoot4 #NullSafety #Java #SpringFramework7 Source Code: https://github.com/JavaaTechSolutions... 👋🏻 Connect with me: Github: https://github.com/JavaaTechSolutions LinkedIn:   / javatech-solutions-b44b352b7   🎟 Join this channel to get access to perks:    / @javatechsolutions   🎉 Thanks for watching the video!.
