[@AdnanAbbasi_LXXVIII]

Thanks so much for providing this, I pasted it and it worked. I guess I had an indentation problem. Another point for the users watching, once you copy paste the content, please go ahead and change the POSTGRES_USER, POSTGRES_PASSWORD to the name and password you prefer 🙂

How to run docker?

[@JustinBae]

Not finished with the video, but this video is much improved over your previous Spring Boot tutorial! Clear, simple explanations, easy to understand. Thank you!

[@milanievlog3138]

For those who find the records in the table deleted after restarting the server, just set the ddl-auto property in data source configuration located in file application.yml to update instead of create-drop.

[@noahgsolomon]

Took me an hour to figure this out and decided to warn those in the comments myself too lmaoo

[@highzenburger1829]

FYI - For those who added PostgreSQL and nothing happened. You have to rebuild the maven project. Right side of IntelliJ Click Maven (turned sideways text) and the refresh looking icon.

[@brians.digital]

Hey thanks for all you do! Just one thing... there seems to be a missing lesson between"DB Overview & JPA" and "Postgres DB"... couldn't find a link to your nicely designed textbook either.

[@jahirulsarker1900]

I learned core Java 17. Now I am thinking of learning spring boot. And started watching you. Your explanation is really helpful for me.

[@liaozhuu]

For the docker part, I couldn't find the link to whatever he was talking about so just brute force type it in, but make sure indentation is correct! If you get the "Error: Unable to auto-detect settings, manual configuration required" try installing docker on your computer first and then try again

By that time, Spring boot ver 4 will be released lmao

[@pikachubolt2001]

Thank you for the Spring Boot 3 Tutorial video! I learned a lot from this almost two hour Spring Boot 3 Tutorial video from you, as you have easily explained some concepts, setups, and configurations in a simple, concise, and straightforward way before coding that we needed to understand first in order to get started, understand, and use Spring Boot 3 efficiently and effectively as a development platform for Java Applications, specifically for web application java development in this video of yours as much as possible for us beginners/learners, though I had expected had UI in browser to showcase the full display of Spring Boot 3 in terms of Java Web Applications Development using the development platform, however I still learned a lot from you in this video that I think that were necessary as a beginner/learner of Spring Boot 3, so thank you very much again for this tutorial of yours as I have learned a lot from this tutorial video of yours of Spring Boot 3, you have gained another subscriber!!!!!!!

[@duttybwoy556]

This tutorial is absolutely immaculate!! And from scratch, with slow perfect clear spoken explanations ... Best one I've seen on Spring Boot.

[@iqbalpahlevia]

wow thank you very much sir. its been more than a year since the last time i am using spring boot. it is very comprehensive.

[@anggarasatria]

MashaAllah brother can't thank you enough for sharing so many valuable materials ! May Allah grant you an endless happiness in the dunya and jannah! Aamiin.

[@hameedferoz8804]

First of all, thanks for this video. But, after watching a few spring boot project videos on KZbin, i feel like, this is the most basic spring boot tutorial. Its for the very beginners. And, I must say, u did a great job there. But, there a lot lot more in Spring Boot like exception handling, not taking duplicate data, Using Response Entity, , Adding http Status to the result, Getting single object data from the user input using Path Variable and Request Param, Mapping Tables and more.

[@МаксимЯрема-е8щ]

Hi Nelson! Could you please tell me where i can get to this page on 35:06? i mean textbook

26 minutes in and wanted to express gratitude for explaining with such calm, patience and clarity! You're an excellent instructor!💜

[@aileenchan3741]

That yml file is so tricky! 😅 but I got it running!

[@MihailJordan]

If you post another video on Spring Boot 3, please include how to build native images with GraalVM (and explain what is the difference compared to Docker) it's the major thing now, I think.

[@aureltrouts]

Agreed, this video is about Spring Boot, not Spring Boot 3.

[@baki3398]

If you are new to development with Spring Boot, this video is good. But when the case you are proficient in Spring Boot 2 + Java 17, you may want to search for other videos.

[@elhadjindiongue1736]

To be honest with you I didn't see the part when you integrate Docker in the app you just said it but I don't know how to do it. When I run the services db container got some errors like "unable to auto-detect settings".

[@YashashwiniS-u3v]

Where can i get the notes/textbook that u r teaching?

[@Jocelyn-cs3xx]

Does anyone know where to get the code pasted in 01:03:39 - Postgres DB ?

[@relaxunwind765]

I don't usually comment but your videos are tremendously helpful for beginners and experienced developers like myself. Keep pushing content, you're awesome!

For the people getting a Internal Server Error with status code 500, you need to include a default constructor inside the Customer class with no parameters!

[@z1d2g3c4]

thankss😁😁

[@rudy5191]

To be added that the 500 internal server error can also be caused by an error in the configuration of your request. Look for typos, whitespaces, or invalid JSON formatting.

[@JideOyebanji-g6n]

Thanks alot. This really helped.

[@samorita89]

Do you still have a web page for all the annotations you're explaining about in 43

[@khanhvu1200]

Hi @Amigoscode, thanks a lot for the tutorial. It is really a great one. I do have a problem at 1:19:15 though, after following exactly what you did, when I restart the program, I could not see the new Customer table created in the log when the application runs. Has anyone experienced the same thing? Any help on how to solve it would be greatly appreciated. Thank you!

[@deveshrampersadh5213]

Same here. Indention looks correct. Logs show: "table "customer" does not exist, skipping" and "sequence "customer_id_sequence" does not exist, skipping" which I don't think is correct

[@JulioGarciaSacristan]

Also the same issue: `SQL Warning Code: 0, SQLState: 00000 ` and then: `table "customer" does not exist, skipping`

The video part after "docker is up and running" seems to be missing in the tutorial. Also I can't see the link to the docker-compose.yml - where can I find it?

[@RineezAhmed]

If you could also do a video on how to migrate from 2.5 or 2.6 to 3.0 I think a lot of people will want to see that.

[@aureltrouts]

Migrate to Java 17 first, then it will be smooth.

[@solarflare1842]

Noice vid, for someone who never saw Spring, although very similar to your previous course on Spring. Skipping some parts I haven't seen much of the new stuff introduced for Spring boot 3 and Spring 6 like usage of ProblemDetail etc... I'd really appreciate if you could present the new features with some neat examples. Rly like your vids!

Everything was going great until the database section. I'm getting this: "org.postgresql.util.PSQLException: FATAL: password authentication failed for user "amigoscode"". I was using a wrong password the first time but I changed it, delete de docker container and created it again with the docker compose command. The login data it's correct now, but I keep getting the same error. Help. :(

[@leoMC4384]

I fixed it. In order to recreate properly the docker container, you need to run the command "docker compose down --volumes". After that, you run the "docker compose up -d" command again and you're good to go. Now I'm back in the course. :)
