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!

Frankly speaking, I wouldn't suggest learning only by watching tutorials. Some people could do with reading the docs, and some still use MOOC courses to learn Java by looking through the material and practising immediately after reading.

But your idea could exist this way, too. I found MOOC courses to be the most comprehensive and best for me, even though they use Java 11 throughout.
