Is there a lot of difference between Spring Security implemented with XML or JAVA?
You can create a project with both XML as well as using Java.
Do any of them have any advantages or disadvantages? From what I saw the XML ends up getting too long and hard to maintain over time.
One advantage of Java Configuration is that it has a syntax error. In the XML configuration, you will only discover the error when executing the project.
Would you have any beginner tutorials that worked with java code?
I recommend giving a search in some repositories of github or bitbucket, follow a link from a project of my college:
Example (To run the application, you need to have the postgreSQL database installed in addition to creating a database with the stockcar name)
Try also, look for some tutorial in English, always have more content to study.
