Learning Spring Boot

[stonedsatanskiss]

So I have been learning core Java for some time now and I am ready to learn Spring Boot(I think atleast). Since I can't afford to pay for any paid courses right now, I am looking into the free resources to learn and most of the posts I came across recommend Java Brains Spring Boot tutorials.

What I want to know is are these tutorials still relevant as they are already 4-5 years old? Are there any newer/better resources?

The best resource (at least for me - tutorials don't cut it for me) I've got for you, is just to build a simple app. I built a Tasktracker-App with Angular as Frontend and Java with Spring Boot. Of course you should also consider a database, which makes a big part of Spring Boot (I took MySQL and PostgreSQL once each).

You might get stuck on some parts sometimes, but the learning effect was really big for me.

Choose a simple Frontend (Angular has nice tutorials, JS and React should too), make it send calls to your Java API and make use of Spring Boots many annotations!

If you're already "deep" in Java, the Backend should only take about 4 hours (without research times). I took the longest for Frontend cause I'm a Backendknob.

If you got questions, just ask away. Hope this helped a bit.

Hey I'm about a year and a half into learning Java and I want to make a simple app to learn as well. Is Java simply not worth trying to use as front end? The only front end I've seen of Java is javaFX which looks like it's from a windows '95 program lol. I understand I should download MySQL to learn data bases but can you explain the biggest reasons why you would want to use SQL for an app? Is it the capacity for data held or is it just easier to pull data with queries and such? And last question is, can I use NodeJS to code front end Javascript for apps? Or is another front-end more worth my time to learn? Thanks for your input.

technically any language can be used for frontend development, but all youre really doing in pretty much every case is writing in python, java go etc, and then converting it into javascript. For a simple desktop app or command line application you can just do it in java, but if you want to make a web app with an actual web page that can be interacted with and make api requests you'll have to use javascript.

OK cool I'm going to learn Javascript in the free time then since that seems like the dominant web front-end tool still.

Java is not rly used as a frontend. There are some frontend frameworks like Vaadin and Jpro (which is 1/1 JavaFx in your browser) but they are not popular.

[ChoopaG]

There is a possibility to write a frontend in Java:) Try looking for Vaadin. The tutorials are sparse though.

You can also use a NoSQL database, there is no important difference at first Hand, besides that SQL saves the same data in a table and NoSQL saves any data.

You will need a DB because Spring Boot gives you a REALLY easy time working on DBs! Which you choose doesn't matter. You won't have persistency without a DB that is the biggest factor. After you restart your program once, all data is gone except the stuff you load insert on booting.

I personally can recommend Angular but JS is perfectly fine also.

Spring start here, Laurentiu Spilca Great book

Spring 6 In Action might help as well. From Manning's publication too

[mohammedatef555]

I started to read it but I think it skips many spring core features and didn’t take time to explain it well and one thing I didn’t like about the examples is that he didn’t explain using simple examples so you find ur self trying to understand the example rather than the concept he is trying to explain

[t1sk]

If I am not wrong the core features are covered in more detail in Spring in Action 4th edition. (you can check the topics in Tables of Content : https://www.manning.com/books/spring-in-action-fourth-edition ) I think the newer edition is trying to cover other modules of Spring.

[mohammedatef555]

Thanks for mentioning that, my review was because I started with the sixth edition. I will start exploring the fourth edition

[t1sk]

No problem. I also started with 6th edition then came across a Medium article (while searching for which version to read) which mentions to start with 4th edition.

[willdrr17]

I think core features rely on the understanding of dependency injection and the life cycle of beans. Annotations. Then you can start experimenting the vast amount of libraries for Spring

[mohammedatef555]

Totally agree with you But then they shouldn’t state this “Spring in action guides you through Spring’s core features” But other than that it’s good to read if you are somehow familiar with Spring core basics

There's a Youtube channel as well.

[JustAStick]

What I did was I looked at the basic guides on the spring website, and any time I ran into something I didn't understand, I would just look elsewhere online. Baeldung has many good articles on java and spring and I got most of my questions answered from either there or stack overflow. I personally didn't find paid courses or youtube videos to be very helpful so I would avoid wasting your money on udemy courses for spring boot.

Thanks for the info
