When to switch to Spring?

Question

Java

I am learning Java Core, writing a simple console chat but I would like to implement it all on the web. When should I start learning Spring and other things related to the java backend? Do I still need to practice with Java core?

Answer 1

After learning about servlets.

Answer 2

You need to practice with Core all the time, and the web is not only about spring. It will not be superfluous to get acquainted with Vaadin - a good and simple interface in the browser a la Swing, which will help you quickly transfer chat to the web using only java. It integrates well with spring.

Answer 3

This is not a sprint, this is a marathon) There is no clear Roadmap here.
The sooner you start learning Spring, the better. If something is not clear, you can always return to Core and see a couple of examples. For free, there are two books on Spring in Russian, which explain everything very well. Once you get to Spring MVC, you need a general understanding of servlets, at the level of a general idea, and why they are needed.
