Thanks for your patience everyone - Here's an updated tutorial making use of the newly released Spring Boot 3.0.0!

[demetriuslewis]

This is my first look at spring and i think this was a great overview. Thank you so much for your time!

[heyEdem]

Thank you so much for this. You explain things so much better. Big fan from Ghana

[madhusudhans]

Thank you. It was very simple and easy to understand.

[omishan]

Thanks, I let github copilot do some of the work but it came out fairly similar, thanks for the awesome video!

[bugizlihesap]

[LTZMSYAL]

Great job! Thank you that was usefull :)

[alessandroscimone]

Good job! I advise you to pay attention to the video quality and the zoom, which is sometimes unreadable.

In my opinion it would be a better project if the user can select a specific date when are creating the tasks. And no just take the actual date

Hey man great video, around 30:00 when I try and run the program, instead of generating the Webpage I get a Whitelable Error Page: type=internal Server Error, status 500), it was an error during template parsing

[mansipandit]

Hey!! iam a complete beginner and your video is very easy to understand but at 29:35 while debugging iam getting error application starting failed and webpage is showing this site cant be reached (im using spring 3.3.3 version and java 22 although i updated my project to new version) please help me iam stuck at this.

How do I handle an error that says "This application has no explicit mapping for /error, so you are seeing this as a fallback.". I get this type of error a lot when I try to use Spring and people say my files aren't ordered correctly, but I just follow the tutorial and class my packages in that order? In general I always have this issue but in specific to this project, when I use @ComponentScan(basePackages = {"controllers"}) i get the home page to show up but not /create-todos then when i remove componentscan, the /create-todos shows up initially but I can get "/" to map :(

[MustafaOzturk-xhqw]

Unfortunately I don't see the Bootstrap implementation on the page. what could be the reason?

[TheFefs]

It worked, I just had some issues with the services, I had to add the getters/setters to make to be able to see the pages.

[shiekhahmar]

Sir I tried to run the code, but it raising an error

[vaiterius]

36:53 How can I prevent copy-pasting html files all the time? Does thymeleaf support generating boilerplate for every html file I want to create?

[notyaniecetv]

ThymeLeaf is making this tutorial impossible to do right now. I keep gettiing "Attribute th:if is not allowed here, Attribute th:text is not allowed here, Attribute th:each is not allowed here" I have followed everything to a T and the dependency was installed at the beginning right along with yours. I cannot find any answers to this online. So until it can be squared away I have to completely abandon this tutorial because none of the other code is wortkign in this file due to those issues.
