[@meletiskorres9905]

KZbin is doing you and everyone a disservice by not having your channel be the first thing when I search for anything relating to spring boot. Please keep posting videos like these. Would be nice if you did a intermediate and advanced course on building complex applications. Thanks again for the great content

[@RaefetOuafiqo]

is this video good for someone who doesn't develop with Java? can I learn something from it ?

[@TheSupremeEmperor]

@@RaefetOuafiqo I know I'm late, but I would say it's crucial for you to learn the basics of Java.

[@RaefetOuafiqo]

how much basics, cuz i already know some other languages @@TheSupremeEmperor

[@timothymcgrath4072]

Thanks! Really enjoying the Spring Boot 3 crash course

[@DanVega]

Wow, thank you so much Timothy! I really appreciate it 🙏

[@AleksandarT10]

Great content Dan! That is amazing! Very helpful for everyone to go through the course! Making more of these would be awesome!

[@vitonkanne4902]

Thanks so much Dan, it was a rollercoaster ride of Springboot very well structured and explained. I was able to learn and refresh a lot of concepts with hands-on. Big fan!!

[@thirue8237]

This is really amazing. Thank you so much for the great content and clear explanation in spring framework.

[@yasemincaliskan5524]

Very well-structured content. Thanks a lot for your all efforts to bring this tutorial to us. It really helped me to understand Spring Boot!

[@vishnugovindan8550]

Thanks for putting in the hours for this! Would love something similar for Spring Security as well :)

[@m_i_g_u_e_l_]

Thank you very much for sharing your knowledge, you are the best. It would be great a video with advanced concepts that are often used in a business environment.

[@zlyuser9656]

Dan, it's a pleasure learning from you! Great content, clear explanation of the topic. Thank you very much for this material. Greetings from Poland ;)

[@andrewsixsixsix]

Dan, you are the man! Thank you very much for all your work! I will not let you down!

[@jp-sc5du]

I will be starting this course. This is just what I need. Thank you so much!

[@nagamohank2244]

Dan, a damn good talk on Spring boot with meticulously knitted content. Thanks again for the great content.

[@vinujalavakumar9635]

Came here with a lot of questions and got a clear answer. Thank you, Dan!!!!

[@neo_story]

I really love your course. Hope to watch and learn more from your lesson in the future!!!

[@parthokr]

After dabbling through a bunch of starter videos I find this just a perfect spot to start my spring boot journey. Thanks, Dan.

[@loyyeeko1231]

Thank you so much, this is so good! get everything started from dev to prod most importantly the core concepts of Spring, thank you Dan!

[@EugeneChanYK]

Thank you so much for this. It really helped me understand better how the Spring Boot framework works and what a lot of the annotations do. And I finally understand how the Spring Boot framework automatically instantiates the classes that we create in our project (with the proper annotations), and thus can automatically be injected into other classes that require them.

[@cod4basterd]

Man, this is top tier content. Your explanations are so good. You clearly explain why you're doing things a certain way, and why you like certain implementations. Really puts things in perspective about why they're useful.

[@zhipengliu4767]

This tutorial is awsome!! Thank you so much Dan!!

[@tzuilee588]

Just wanna give you a huge thanks! The last two sections are super helpful and intuitive!😁

[@LukeGJPotter]

Thanks Dan. You had a very good explanation of Profiles. And I learned some new Annotations for the Rest Endpoints.

[@6Sambora]

LETS GO!!!!!! 🥳 My weekend to do list

[@DanVega]

Yay! Let me know what you think of the course.

[@saravanansaibaba8374]

Great video. I have been working on Spring Boot quite while now and found this as great refresher. Thanks Dan.

[@mayur2038]

Learned so many new things in spring Thanks so much ☺️

[@ngenge_senior]

This is by far one of the best Springboot tutorials for beginners that I have encountered

[@Alex-bc3xe]

I can sense immediately who is a great teacher and who's not, and this man is awesome.

Decent tutorials. From now on, These will be my cornerstone before watching other tutorials. You explain answering what, how, and why questions based on the foundations. Thank you so much for sharing. God bless you!

[@DannyONealCodes]

Dan Vega has the best Spring Boot videos on KZbin, hands down. Other contributors leave me with questions that Dan answers right away.

[@krzys2702]

Very good tutorial! Really helpful! Keep up the good work👍

[@BenjaminBASSET]

You really save me thanks ! Difficult to find a real complete tuto on this subject. I am greatful.

[@arsenico4126]

By far the best crash course I've seen for springboot. Dan, this video is insane. As a student, you've answered questions that other youtubers and even professors don't take a second to even explain, thus making understanding vital concepts so much easier so thank you for that. The only bone I have to pick is that the frontend part of the project wasn't included in github or explained really in the video making it a bit harder to follow along.

[@medorox]

Omg finally I found I video that explain spring boot with simple way no complicated explanations I really recommended for you guys. Thank you Mr Dan Vega you are my angel ❤

[@rafaeldepaula381]

Dan, you're awesome. Thankss for the content.

[@maxjung6845]

I would also like to say "Thank you very much!". Very nice approach from you to first show how to implement things by hand and then demonstrate what Spring / Boot has to offer to just not have to write a lot of things yourself. Big kudos.

[@heidiemiliaholappa]

Thanks Dan, I found this tutorial very helpful! The course was well structured and you explained everything with great clarity. Subscribed and will be looking more of your tutorials in the future. :)

[@chandan07talreja]

Amazing video Dan. Loved it!

[@francoisschoeman5350]

Coming from Django and Next.js, Spring and Spring Boot is very low level and very difficult to grasp the concept of, especially with the way that their documentation is laid out for Java/Spring beginners. Thank goodness I had prior C++ experience, otherwise the concepts would be too difficult to understand... Thank you so much for all your hard work into putting these long practical videos out there, for free. It would've been waaaaay harder to learn Spring without your channel! I hope you get the recognition that you deserve. You definitely earned a sub!

[@ravikiran-uu3bu]

Thank you so much.. very clear and concise

[@deyviddimitrov2967]

Greetings, Dan! First of all I want to admire your work - you have the best content out there regarding software engineering. I did really like the way you've explained JWT and Spring Security 6. There is one thing I've wondered - do you plan publishing a video about securing microservices? In case you don't can you recommend any channels, topics, books or whatever which is explanatory and useful enough. I do understand most of the concepts out there but I suck at making them work altogether. Is it worth even using JWT? What are the differences between having security in dev vs production environments? Is Spring Security even good in Production? Should I have different implementations for requests comming from external calls and the ones comming from internal service? Is the Authentication one another service? Have an amazing day!

[@akinwumikaliyanu4022]

The best course on youtube so far. I am coming from a python & golang background and I must say this course is just too nice.

[@addisjigssa5304]

The best Crash course; actually more than a crash course!!!

[@adriencbl]

Thank a lot; you justify the code by explaining the theory behind Spring and it's very interesting and improve the understand !!! I love

[@manivannankarunanithi8272]

Thank you very much man.. you are doing a great job.

[@Brian12010]

I watched many tutorials with java + spring and wasn't exactly sure of java logic as it has been a while since i have messed with java. Other spring tutorials zipped past java logic (rightfully so since it is focused on spring) however your video went the extra step and explained the java code (before spring came into play) and made it clear. thank you!

[@user-xq9cd5zb2r]

great course dani. Amazing !

[@mehnaazmohiuddin]

Thanks!, You are such a great teacher because you are really showing the problem which we naive people do, people who only knew plain old java and you take it from there and show how springboot helps. CLAPS . You have clarity and you are giving us clarity ! Ace. I have completed this course and sent it to production :D . super clear :) thanks thanks thanks . your stuff is gold. really

[@ThePaulFaulkner]

Great video Dan, thank you

[@serenalin2605]

Awesome Spring Boot Crash Course!

Thanks for the great video. I would recommend in almost all web programming videos, discussing what is "the problem we are trying to solve" and "what are the advantages and disadvantages of our options."

[@unda25]

You are a genius in teaching , after I have been learning Java for nearly 3 months I can build something and understand a lost how this server works and how strong the JAVA environment is

This helped me to redo the project I did in python flask when I started learning about rest apis

[@peterMwaura-rh3nm]

Very informative. Thanks

[@michaellebediev6715]

@DanVega thanks a lot! It's real pleasure to learn with your help! Could you pls think of making in future deep course about JPA with details like auditing functionality?

[@robinmathur5807]

Very fine and clear content, big thanks from me.

[@ohmpunk]

Haven't been through the whole video and the course yet, but I have a feeling that this crash course quality is quite better than plenty rubbish things on Udemy (which I wasted a lot of money for them) as I skim through your clip. Thanks very much for this.

[@mrMarseleene]

omg, instantly like before watching, greate job, Dan

[@CK-bu5wh]

Hi Dan Merry Christmas!!! I finished this video today! I am a completed beginner of spring boot! Your video really helps me build a good foundation of it. I wonder if I would like to deep dive into the next level of spring boot, what are the videos would you recommend me to watch next ? And, really appreciated for putting the great effort on creating this crash course video ! ❤

[@satishb2752]

Hi @Dan Vega, its simply super, covered many concepts, it would be great if you can cover security in future.

[@adonsav]

Nice and neat tutorial! Thanks a lot for your effort.

[@DanVega]

Thank you so much for that, I really appreciate it ❤️

[@shantanudutta9327]

Great content Dan!! Thanks for creating such a helpful tutorial! I really learned a lot following your tutorial. I selected Gradle instead of Maven in Spring starter template. In this regard I faced some issues deploying the application in Railway so had to do following changes. Hope this helps someone. 1. I had to create a `nixpacks.toml` file with following content to resolve "no main manifest attribute" error which I was getting in Railway deploy logs: [phases.build] cmds = ["./gradlew bootJar -x check"] 2. The Railway Postgres service DATABASE_URL environment variable is no longer uses other environment variables (e.g. PGHOST, PGPORT, etc.) but hard codes them so I had to manually replace them with environment variables in code. 3. I had to manually create references to Postgres variables inside the Spring boot project imported in Railway since they were not auto exposed.

[@giovannifrison6941]

Hey Dan, Thanks for the awesome videos as always! Could you make a video about Spring and SpringBoot certifications? If I'm not wrong the only "official" one is from VMWare but the accessibility requirements and the costs are pretty cryptic! Thanks and have a great day!

[@thiago.almeida]

Hi Dan! Wonderful video. I'm almost switching to constructor injection but I'm now thinking about my components that extend (inheritance) an abstract class that has some code using other dependencies. Today I can just @Autowire them in the abstract class and spring will solve them for me without my components needing to know anything about it. What do you think about this? I already do composition over inheritance whenever I can, but some problems are solved better with inheritance.

[@shanvi4019]

Amazing

[@leoMC4384]

Thank you so much Mr. Vega. I'm a self taught software developer myself and I'm learning Spring Boot but most tutorials I found were made with Spring Boot 2, so I have to change many things in my code because it crashes often. And the worst: the teachers are indians with horrible accents that I can't understand most of the time. So I'm glad KZbin finally recommends a great tutorial: updated and in properly spoken english. 👏👏👏

[@congdatt]

Hey. Many thanks for your videos. Iam currently learning Spring 🎉🎉🎉😂😂😂❤❤❤

[@kukli700]

I'm studying CS and got a new course about Java and Spring. Lectures were terrible and then I got into your channel. You are doing such a great job and after seeing some of your videos I really understood and loved Spring. Thank you so much for that Dan ! Greetings from Poland.

[@marcw6875]

I'm kind of envious that your classes even touch on something like Spring. I just finished a CS Bachelor degree a little over a year ago and we never touched anything like Spring. It was all just pure Java, Python, C, or whatever language that class happened to be using.
