Why Java Spring & Java EE Feel Complicated? 1. Steep Learning Curve – Many concepts (DI, AOP, Beans, etc.). 2. Too Many Configurations – XML, annotations, properties. 3. Heavy Abstraction – Lots of layers (Controllers, Services, Repositories). 4. Enterprise Features – Security, transactions, messaging add complexity. 5. Dependency Management – Maven/Gradle configurations can be overwhelming. 6. Version Differences – APIs change frequently (Spring Boot simplifies this). 7. Java EE is Heavy – Requires full app servers (Jakarta EE is improving it). Solution: Start with Spring Boot, avoid over-engineering, and focus on practical use cases. read less
