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.

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...

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

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.

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.

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

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

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.

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.

Thanks Navin. This is fantastic. I've been trying to grasp SpringBoot and other Java concepts such as interfaces, anonymous classes, and lambda and just not got very far. But your videos explained it all.

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

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.

DON'T GO NOWHERE ELSE ON RU-vid 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

This is for those who are trying to create a jsp file On your, Spring Tool Suite go to 1)Help Menu 2)Select Eclipse Marketplace 3)Search and install Eclipse Enterprise Java And Web Developer Tools and then restart

I love the fact you used the familiar JSP, Servlet and gradually make transition to MVC and REST. Helped me tons to understand what Spring Boot does.

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!

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! ✨

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👍📚

I have tried many tutorials for Spring Boot before yours, but I would admit your tutorial is crisp and simple. Liked the way all the examples have been designed, easy to follow along. Thank you for creating this amazing content.

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.

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) spring.jpa.defer-datasource-initialization = true 3) don't use double quotes ("") use single quotes('')

Hi Navin. I like your multiple explanation. Thank you for your valuable work. I really appreciate it.

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.

Your exposition is simply excellent. You ask and answer questions such as "how does it know where to pick up X" rather than just show the code and leave it as magic. You connect the dots well.

In the last Part. "19 Spring Boot Data REST Example" , you need to add "spring.jpa.defer-datasource-initialization" to application.properties. Otherwise the Script runs befor the table created. application.properties looks like ... spring.h2.console.enabled=true spring.sql.init.platform=h2 spring.datasource.url=jdbc:h2:mem:testdb spring.jpa.defer-datasource-initialization=true

I just pause the video and want to tell you a BIGGGGGGG THANK YOU SIR. Really in Spring i saw so many videos to understand this but first time i came on your channel and you are superb, i have no words so thankyou

I've just finished watching the whole video... This is a masterpiece! It's the best Spring Boot Video that I've ever watched and I left feeling very comfortable with Spring Boot after days of struggle. Thanks for sharing all of this, Mr. Navin. You're amazing!

Whenever I have doubt or need clarification in any technology , always my google search will be for your videos. Your way of teaching is simple & deep . Thank You Master !😀

Really loved this tutorial. I appreciate you explaining your thought process and being empathetic to our thought process when trying to learn.

Awesome Tutorial Telusko. Thank you for sharing your knowledge with the community, people like you are who are what makes us reach further.

Why are you so amazing!!!!! Thank you so much for making it free. Looking forward to more .of your videos!!!!

Sir, you are a legendary teacher. I paused my video to just comment on this because I am extremely satisfied with your teaching and I am understanding every difficult detail to point out just because of your clarity in teaching.

I have seen many other tutorials for spring and spring boot .. but nobody explained like this. this video makes me completely understand about DI, Autowiring, and spring container. and spring boot .. a very good explanation..and an amazing video.. thanks a lot!!

After of days trying to understand Spring, i finally did because of this video.Thank you very,very much.

I was working with spring and spring boot since one and half year but I don't know the exact concept of dependence injection and this video made it clear for me thaks so much.

Awesome way of explanation....Your way of showing possible errors after using a concept is the usual way a beginner will go, but gets stuck and spend time to resolve. Thanks for not only saving a beginner with learning time, but also to retain the learning interest thereby.

Sir, you are awesome. I have learned Java by watching your videos and now I have learned SpringBoot by this video. Your explanations are always concise and to the point. Thank you so much Navin Sir.

Just finished. Great tutorial. Every example is fully-functional, explained coherently, and introduced in a logical order. Thanks again, Telusko!

Explained everything in such a simple manner. Loved this video. Thank you for giving us clear view of Spring boot.

Hi Navin, thank you very much for your generosity, I learned a lot from your classes !!! I really appreciate your work. Thank you so much !!!

Thank you so much for this explanation. Only due to your video series I understand all the concepts very well, and feeling comfortable enough to work on projects. Thank you.

it's very informative, right to the point. Greatest video on Spring by far I have seen till now. Keep it up

OMFG What a freaking GREAT resource!! Thank you thank you thank you! Over the last 2 weeks I have probably tried 2 dozen tutorials, videos, documents and and blogs on Spring Boot, and each one left me more confused than when I started! This explains everything, why we need it, how to use it and what it's doing in the background. I'm halfway through the aggregated full course video, and already can do more in Spring Boot than I could with all the other resources combined. This is wonderful.

Million thanks for producing such quality content..Even this on springboot was best as usual!!! God bless you, Navin.

I've been doing web development for 7 years. I've used all types of languages: scripting, OOP, strongly, loosely typed, interpreted. There is nothing like the feeling of writing and building in Java. Too easy to reason about is a good thing. It's srsly too easy to reason about because of the architecture that OOP gives. Love it

god,..... this is i been waiting for clean clear and perfect... you are a genius instructor

Since this tutorial is beeing a bit out of date due to the new Spring framework beeing released there is one step/line of code that needs to be added in application.properties at 1:27:00. That is "spring.jpa.defer-datasource-initialization=true" - since my newer spring framework was throwing out an exception "table ALIEN not found" and this new line in app properties managed to create database on initialization with Entity annotation. Full exception: Error creating bean with name 'dataSourceScriptDatabaseInitializer' defined in class path resource [org/springframework/boot/autoconfigure/sql/init/DataSourceInitializationConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement #1 of URL [file:/C:/JavaProjects/Servlet2/bootjpa/target/classes/data.sql]: INSERT INTO ALIEN VALUES ('101', 'TIN'); nested exception is org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "ALIEN" not found; SQL statement: Usefull documentation where I found an answer: docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto.data-initialization Anyway sir, thank you very much for this excellent content!

Watched the whole video. Amazing effort and lot of knowledge to gain Thank you so much for helping us out. Working with java from last 1.5 years and your videos helped a lot. :)

I really appreciate you Mr. Navin, I am zero in Spring boot, I searched many tutorial, but according to my knowledge you are my best spring boot master, keep your services, God bless you

Man, God Bless you, you made a really awesome spring tutorial, I learned a lot. Thank you.

You have made my day. I am truly enjoying your video, and the way you break up different concepts into simple to understand terminology. I love it man! keep it up

Thank you Telusko. This was just amazing information shared in a very clear way. Awesome explanation to each and every concept covered in the video as always.

hey telusko, your way of teaching makes me the tough concepts very much easy n clear...you earned my heart

Navin, your way of teaching is really cool ! Having worked in the industry, what I like about your method of teaching is that you create an exception and then fix it. This way fundamentals get clear why we are doing what we are doing. It also helps debug issues in real time applications. Increases confidence level. I enjoyed watching and learning your videos thoroughly. It is said how we do anything is how you do everything. All your videos I have gone through are simple, complete and best part is short :) I wonder if your free classes are of this quality, how would your paid classes be!

Great content with brief description and excellent teaching. Kudos to you Navin. And this is free and thanks for your efforts, it's a great feeling to learn spring boot in short time.

I'm about an hour in, and you've done very well with this. You've saved my brain from unknown amounts of frustration.

Excellent explanation. Loving your videos...I'm totally new to Spring (boot) and you are making the concepts understand in a simpler terms than using technical jargons...

A great teacher indeed. Thanks a ton for such valuable efforts.

Big thanks to you sir for helping us by providing this premium content in free of cost ♥️

Very clear and straight to the point especially for a beginner like me, I'll make sure to buy your courses in the future but keep the free content please, thank you sir!
