Java tutorials from easy to hard for beginners (in the context of the Web)?

Question

Java

Good afternoon!
Faced the following problem. I need to train an intern to develop web-oriented java applications as quickly as possible. Can anyone share links to good "step by step" tutorials?
Trainee(s) with no java knowledge or with java se knowledge. There is an understanding of the web on the example of other programming languages.
As a result, they must operate Spring MVC applications.
I myself understand this topic, but at the thought that I should help someone in this, I start to get confused, as it is difficult to build the correct sequence of training.
