🚀 @Component vs @Service vs @Repository in Spring Boot Through my experience working on Spring Boot projects, I’ve learned that using the right annotations is essential for building well-structured and maintainable applications. Early in my career, I used these annotations interchangeably. But with experience, the differences became much clearer 👇 🔹 @Component I typically use this for utility or helper classes that don’t belong to a specific layer but still need to be managed by Spring. 🔹 @Service This is where most of my business logic resides. Whenever I implement core application logic (validations, processing, workflows), I prefer using @Service to maintain clear separation. 🔹 @Repository I use this specifically for data access logic. It also provides exception translation, which is useful when handling persistence-related issues. 🔹 How I Apply This in Projects @Repository → Database interactions @Service → Business logic @Component → Common utilities 👉 Key Takeaway: Using these annotations appropriately helps maintain a clean architecture and improves long-term maintainability. 💡 In my experience, proper layering makes debugging easier and collaboration smoother in team environments.

Love to see where RBAC/ABAC rules for EGRESS go ;)
Totally relatable!! many of us start by using them interchangeably 😄 Clear separation with @Service and @Repository makes a huge difference in maintainability and debugging.
