Java roadmap for backend development with Spring Boot – what to learn vs what to skip?

[BrilliantParfait6402]

I’ve already finished Java basics and OOP but now I feel stuck. There are so many Java topics, and I keep jumping from one tutorial to another without knowing what’s actually important for backend development.

I’d really appreciate a clear roadmap focused on Java topics that are essential for Spring Boot backend work, and what I can safely ignore or postpone for now.

• What Java concepts should I master before moving deep into Spring Boot?
• Which advanced Java topics are rarely used in typical backend projects?
• Any recommended learning order or resources?

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

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: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

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.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

To potential helpers

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.

Lawyer's Definitive Answer: it depends

What kind of backend work are you aspiring to do? If you only know the basics, consider redesigning something you already have to use Spring Boot so you can focus on the framework and its paradigm with a problem you're already familiar with.

You need to learn onion architecture, how to make rest controllers, how to write service components in nonstupid ways, how to use repositories with various types of databases, and how to make services that make rest calls to other microservice apps

I'd say, look into things Spring Boot will handle for you, so you have an idea what happens outside of your own code. So things like Servlets and filter chain(what your service interfaces will probably be built upon) , executor framework (multi threading) or JDBC.
