Session
The Problem: Modern Java applications often become prisoners of their frameworks. While tools like Spring Boot and Quarkus accelerate development, they create hidden costs: vendor lock-in, bloated dependencies and rigid architectures. What happens when your project outgrows your framework or a new, better tool emerges?
The Solution: This talk introduces a layered approach to Java development, isolating framework dependencies while keeping core logic pure with Java and Jakarta EE. Through examples, you’ll see:
- How to decouple business logic using JSR standards
- Strategies to replace framework-specific annotations
- Cloud integration without framework coupling.
Trade-Offs: Yes, this demands more upfront effort like writing custom persistence layers, rigorous tests, and meticulous docs. But the payoff is code that’s adaptable, testable, and maintainable across frameworks, teams and decades.
Key Takeaways:
- Practical patterns for agnostic design.
- When (and when not) to adopt this approach.
Join me to rethink Java development: less framework magic, more future-proof code.
