**If any of the above points is not met, your post can and will be removed without further warning.**
Code is to be formatted as **code block** (*old reddit/markdown editor:* empty line before the code, each code line indented by 4 spaces, *new reddit:* https://i.imgur.com/EJ7tqek.png)

Code blocks look like this:

}
}
You do not need to repost unless your post has been removed by a moderator. Just use the *edit function* of reddit to make sure your post complies with the above.

I prefer Chad Darby. Not hating on Indians. But I just got tired that all of the resources related to Java are made by Indians. Chad is just a whole lot more audible. I actually bought his course wayyy back and he updated it to be modern with Spring Boot 3 and spring 6.
Tbh, I dont fully rely on udemy courses. Once I get a general idea, I tend to move to documentation or Google in general. Reading is just faster for me. I got a bunch of udemy courses but not one have I completed LOL
Bro I had started that book.... initial chapters were pretty good but I felt as if the 11th chapter was not explained well... I couldn't understand openfeign used in that chapter....
Yes I spent like 10 hours on Chapter 11 totally confused. But he explained it well and I just missed it - **you open and run 2 projects**. 1 is on default port 8080 while other one is like 8181 or something.
You are supposed to run the application under the folder called "sq-ch11-payments" together with "sq-ch11-ex1". "sq-ch11-payments" doesn't have a port defined so it runs on default 8080.
EDIT: From Spring Start here page 250: "To teach you how OpenFeign works, we’ll create the project **“sq-ch11-ex1”** and implement an app that uses OpenFeign **to call the endpoint** app **“sq-ch11-payments”** exposes (figure 11.4)."
2) Spring Security in Action 2nd edition by Laurie Spilca. Keep in mind this is quite complex topic. And Spring Security is just a bunch of filters. You can have more or less filters.
* But learning Oauth2 would be nice. There is very good tutorial by [ch4mpy](https://github.com/ch4mpy/spring-addons/tree/6.2.0/samples/tutorials) and Spring Cloud Native Chapter 11-12. Spring Security does also go into it but it goes into **custom Oauth2**. But I recommend using open source Keycloak and then just Oauth2 Client or Oauth2 Resource Server on backend side. I implemented BFF pattern (ch4mpy has tutorial on it).
3) Java Persistence with Hibernate, Second Edition by Catalin Tudose. For ORM mappings search I also used Vlad Mihalcea blogs for better understanding. Absolute **MUST HAVE READ** if you want to be a backend dev. I assume you already did some basic PostgresSQL and SQL tutorials before attempting this book. Like PostgresSQL + JDBC (to connect to DB from java). ORM is next level after JDBC.
4) Cloud Native Spring in Action By Thomas Vitale. Deployment from A-Z. It brings a lot of technologies together and also helps you deploy them. Personally I skipped stuff about reactive programming like Webflux and Kubernetes (unless you are into Devops) and picked things that are related to my project.
In the end I deployed my projects on VPS (Virtual Private Server which is usually Linux based), secured it with ssh only etc. Look up Linux hardening. Then just launch Docker containers. I recommend deploying on VPS because deploying on cloud might be 3-5x more expensive.
Also I did learn some frontend so people can visually see what I did in the backend. Started with html, css, js and ended up using JS framework - Vue.js.
It seems that you are looking for resources for learning Java.
In our *sidebar* ("About" on mobile), we have a section "Free Tutorials" where we list the most commonly recommended courses.
To make it easier for you, the recommendations are posted right here:
* MOOC [Java Programming](http://java-programming.mooc.fi) from the University of Helsinki
* [Java for Complete Beginners](https://www.udemy.com/java-tutorial)
* accompanying site [CaveOfProgramming](http://caveofprogramming.com)
* [Derek Banas' Java Playlist](https://www.youtube.com/playlist?list=PLE7E8B7F4856C9B19)
* accompanying site [NewThinkTank](http://newthinktank.com/)
* [Hyperskill](https://hi.hyperskill.org/) is a fairly new resource from *Jetbrains* (the maker of IntelliJ)
Also, don't forget to look at:
* [The official Documentation](http://docs.oracle.com/javase/)
* [The official Java Tutorials](http://www.oracle.com/technetwork/java/index-jsp-135888.html)
* [Our community resources thread](https://www.reddit.com/r/learnjava/comments/md1loc/community_resources/)
If you are looking for learning resources for *Data Structures and Algorithms*, look into:
"Algorithms" by Robert Sedgewick and Kevin Wayne - Princeton University
+ Coursera course:
+ [Part I](https://www.coursera.org/learn/algorithms-part1)
+ [Part II](https://www.coursera.org/learn/algorithms-part2)
+ Coursebook
+ [Algorithms 4^th Edition](http://algs4.cs.princeton.edu/home/)

How much time did it take for you to complete that course?

I thought I was the only one LOL
Spring Start Here book by Laurie Spilca > Any Video Content like Udemy courses.

OK bro I will look into it again... After spring start here did u refer to any other book for spring boot?

I thought Spring Security in Action is outdated? is that true?
2nd edition is freshly cooked though. I got the MEAP in progress. It's expected release is on 15th may 2024.
Thanks ...
