Spring Boot 3 raises its minimum Java version to 17 because Spring Framework 6 moves to Jakarta EE 9+, ending support for the javax.* namespace, and Oracle stopped free updates for JDK 8, making migration essential for security, ecosystem compatibility, and to leverage new language features and Spring‑Boot‑specific improvements.
This article demonstrates how to combine Spring Boot's @ConfigurationProperties with Java records to create concise, immutable, and type‑safe configuration classes, covering scanning setup, record definition, YAML binding, constructor injection, validation with @Validated, and best‑practice recommendations for managing configuration in Spring Boot 3.5.0.
This article examines the drawbacks of Lombok, demonstrates how replacing Lombok annotations with Java Records and MapStruct improves readability, type safety, and debugging, and shows the concrete benefits of reducing boilerplate and achieving compile‑time safety in Java backend projects.
This article examines the drawbacks of Lombok—such as reduced readability, IDE instability, and debugging challenges—and demonstrates how replacing Lombok annotations with Java Records, explicit constructors, and MapStruct for mapping yields cleaner, type‑safe, and maintainable code while eliminating boilerplate.
