lets take a moment here to thank this guy for putting this content on youtube for free.

[faybocorpuz]

I've been struggling to find a good youtube source that teaches me Java. No BS, you are that source. I've seen a ton of your videos and I hope you don't stop. Thanks man.

[saiprasadraktate]

Your way of teaching is unique. Instead of just showing the program flow you actually go deep into each concept. Thank you for making everything easily accessible.

[BirgaLock]

Yes this was the best Introduction to SpringBoot I've seen on youtube thus far. Good work Navin!

[bettatalks]

This was the most useful and friendly Spring Boot tutorial I have found on the internet. Thank you so much!

[rishabhshukla]

Thank you so much! ❣️ I am a July 2021 passout and am not from a CS/IT background, but was interested in Computer Science, hence I joined Accenture at a package of 4.5 LPA. After 6 months of working on myself, I've finally received an amazing offer, a 400% hike, from a product based company. Your videos helped a lot, I don't come from a very good financial background, hence it means a lot to me. Thank you so much! ✨

[yashovardhan]

Hey Naveen, I can't express how much I feel grateful for this video. You just summarised the entire springjpa in one single video and that too so amazingly. Content like this makes the learners appreciate genuine teachers like you. God bless you man...

[pratikray]

A really really great effort realised wonderfully. It's amazing to see such rich content and huge effort being released for free. Keep up the great work. The next generation of coders owe you.

[TavoZapata]

I've seen the first 45 min and I'm loving it. Finally, a tutorial that truly explains the concepts of Spring Boot. You are a legend!

[emansurcuber]

I spent weeks in a boot camp with no one being able to explain dependency injection. I finished applications where I had no idea what @autowire meant and I've seen so many videos that struggled to explain this to me. In 35 minutes I learned concepts that I had no idea about after multiple weeks of learning them. Between the simple drawing and the simple application example I just had a massive leap forward in understanding. Thank you very much.

[benkimoon]

DON'T GO NOWHERE ELSE ON YOUTUBE IF YOU ARE SEARCHING FOR A GREAT SPRING TUTORIAL IT IS EXPLAINED VERY VERY VERY WELL HERE !! Thanks to this guy for such a great effort :D

[svpglb]

I have no words to express my gratitude to you, thank you so much. I have learnt a lot in these 3 hrs. more than 3 years in my college days.

[patrickjane]

Finished the entire thing today - from not knowing literally anything about java, apis or spring - i feel a million times more comfortable with this area. Thank so much.

[umapathy]

Great work Telusko ! Absolutely delicious stuff ! No one can easily explain the concepts of spring container, dependency injection & mapping this easily. Feeling much more confident in spring boot concepts especially JPA stuff & power of annotations.

[chithrasubramanian]

You are an awesome teacher with great communication skill. I have gone through only initial few minutes of your tutorial, but had to pause and add my comments. Keep your great work going. You are, for sure, enlightening many developer's life. THANKS

[riz.k]

You are a life saver bro. I watched your videos throughout my university days and even today when I am working as a professional, you are still the most relevant guy.

[nidhisharma]

Such an excellent video covering concepts from Spring DI/IOC, MVC, Boot and Spring Data Rest. Thanks a lot!

[rajaramsavant]

This is the first time I completed any tutorial at once. The reason is that.. You have explained it in very well manner which made it so interesting. It's very hard to find so many important concepts in just one tutorial...Thank you so much. Keep sharing knowledge👍📚

[abdeali]

Those who are facing problem with H2 database Initilizaion :

1) data.sql --> just rename the file to import.sql and re launch your application.
2) = true
3) don't use double quotes ("") use single quotes('')
