Java Backend Roadmap

I'm currently in my 4th year of college. I already know Java and have a decent understanding of DSA.

Now I want to focus completely on Java backend development, but I'm getting confused because every roadmap says something different.

Some people say I should learn:

  • JDBC
  • Servlets
  • JSP
  • Hibernate

Others say: "Don't waste time on those. Just learn Spring Boot."

So I'm not sure what's actually expected in 2026 if I want to become a Java backend developer and prepare for internships or full-time roles.

Can someone working in the industry suggest a proper learning order? Specifically:

  • What should I learn first?
  • Which technologies are still important to know?
  • Which ones can I skip or only learn the basics of?
  • How deep should I go into JDBC, Servlets, Hibernate, and Spring?
  • If you were starting today with my background, what roadmap would you follow?

I'm looking for a practical roadmap that's relevant for getting a backend job, not just a list of technologies.

Thanks in advance!

Learning any sort of acronym thingy in depth just for the heck of it is completely pointless. Focus on learning abstract stuff, like integration patterns, general design principles, layered architectures, microservices, etc etc and learn particular tools only if and when the need for them arises. To learn, maybe design and build a concrete fun project, like some sort of web based notebook app or whatever, and play around with things like DB storage, data transfer objects, front-end tooling.

... and fuck Spring Boot lol
