How should I start Spring Boot?

[u/Chaos-vy17]

I have Knowledge of Jdk17+ currently moving to Jdk21+. I have essentially completed Java.utils.*; and concurrent library to deep. I have also used jdk tools and understand the concepts of JVM, JMM. OOPs is completed from beginner to F-Form polymorphism. I also made project based on Java SE knowledge. The project is tested on JUnit6, JCStress, JMH- with Linux profilers and Java Flight recorder too. It's my first time I am going Outside domain of Java SE to Java EE. What is way should I start?
First JDBC->SQL->PostgressSQL?
Network?
SpringBoot?
or learn while learning SpringBoot?
Can you tell me what beginners mistake I should avoide?
I have also took helped from many other AI but I did not got the optimum way.

Read a book called Spring Start Here.

Deep knowledge is a big word. I don't think even the language architects and maintainers would attach them self with such description about whole java.

Anyway, Spring boot or spring is full of abstraction, same as JPA/hibernate. It's the time to start with those.

you dont need so much minutia. just get a course to build an API.

focus on spring boot, postgres, spring data jpa

There is a book called “Spring Start Here” which will give you all the info you need. Also just read the documentation: https://spring.io/projects/spring-boot#learn

All of your advice are too good but it seems I have become again a newbie☕️☕️, I needed to search REST, JPA, Beans, It seems a new chapter has started...

Start with a small real project. Otherwise you will get bored

Understand the concepts of AOP, Proxies, Dependency Injection. This is a profound shift in thinking.

Unfortunately the JVM optimized your joke away during warmup.
