What is worth learning in java ee?

Question

Java

Hello everyone, I just recently started learning JAVA EE, writing in Eclipse as a database using MySQL. Now I know how to write servlets, filters, jsp files, and I also know how to use basic hibernate queries (select,insert,update,delete). But still I want to know what is relevant now and advice on how to properly study java ee in general, since I think to go completely into this area.

Answer 1

Now it is relevant to use Spring (Spring IoC, Spring Security, Spring MVC, Spring Data, Spring Boot, Spring Cloud, Spring AMQP ... etc) in conjunction with Hibernate or EclipseLink, UI frameworks - GWT for example (we use it). About correctness - first study JAVA EE technologies, study SQL, PL / SQL, and then delve into Spring

Answer 2

JDBC
With it, you can run programs. There are Devcolibry tutorials on YouTube. The basic methods are described there.
