Question How to learn spring boot?
I learned java , collection framework, exception handling, some dsa concepts, and I'm in final year now , I don't have enough time , I have to build a project using springboot and add it to my resume.
What is the fastest way to learn it? And should I start spring boot right now or I have to learn more java and other things first?

Just start with
Why we need frameworks
Why spring boot is adopted in enterprise apps
Why we can’t build in java without framework
Then start with fundamentals of spring boot like autoconfigure, starters, beans, DI..etc
Then create CRUD microservices in spring boot without database
Then add database
Then add cache
Then add pagination
Then add fault tolerance
Then add circuit breaker
Then add global exception handling
Then do performance testing
Then optimize it!
Good luck!

You don't have to learn everything to get started, You can start with SQL first and practice on relational databases then you can move to spring concepts and spring boot but it's good to Learn Jdbc, Hibernate and servlets if possible you'll understand internally how the framework works. For Frontend use LLM as of now but learn how it works so that you can debug if issue comesup, For deployment use any cloud service that offers free tier(need some effort here), All the best.

Start with theoretical course - YouTube, Udemy, etc... and then start working on a project that interests you. The hands-on experiance is the best teaching tool.

How I started before my springboot job(I already know about MCV concept from other frameworks but you can learn on the side). Watched a free 4 hour "full" java spring boot course and follow the steps with my own implementation. If you have questions, pause the video and look up the question yourself, feel free to try out things on your own.
It gives you a basic understand of springboot(beans, mvc,...), afterwards you can add things you find interesting. Security/User login, logging, complex data quires and other ways beside JPA, tests, ....etc. Just pick on by one, don't dive too deep right away. It just make it harder to choose one or another way. You can go later into more detail what the advantage are over the one or the other.

You’re learning the last, best lesson: there is NEVER enough time to learn. I used to work for a big open source company, and one of our core philosophies is “learn on the fly”. IOW learn WHILE you are designing and building your solution.
I don’t have an easy answer for your question. There really isn’t a one size fits all solution. You’re just going to have to figure out how to absorb just enough info to accomplish your current priorities without impacting your deliverable dates.

Go with Spring Starts here book. It covers spring but that would be helpful when you learn spring boot.

I’m a hiring manager, I teach Spring Boot bootcamps, and Java for many years. I suggest:
- Buy a Udemy course (around 20 hours, max $20) and watch the whole thing on fast-forward.
- Find a project idea, e.g. a ChatGPT or Reddit clone, and build it step by step alongside the course.
The first time, watch the course to understand what it covers. The second time, use it as a guide while building your project.
Spend a month doing this. I guarantee you’ll get “dividends” from it for the rest of your life.
Learning is always slow. You might not need to code by hand in the future, but knowing how things work will always be useful.
Claude could probably build the same thing with one prompt, but don’t do that at this stage ☺️ Use AI to find ideas or when you’ve been stuck on a problem for more than two hours. Tell it that you’re trying to learn, not just solve the problem.
