spring or spring boot

Opened this issue · 2 comments

I have gained good knowledge on core Java, jdbc and JSP . So like to start spring or spring boot, i have no idea where to start. There are lot of module, confusing.
Give me structure and plan to start for software job.

If you look at the topics in the Spring Reference, at the beginning the important ones are:

  • Core: IoC Container, Resources, SpEL, AOP (not too deeply, just the notion of proxies and how they work)
  • Data Access: Transactions (make sure you understand how AOP proxies work), DAO Support, JDBC
  • Web Servlet: Spring MVC
  • Testing: Spring MVC Test

I'd just inspect this documentation and use the material of this course in parallel. Note that:

  • Mostly Spring isn't something important to learn - rather what Spring uses underneath is important. That's the complicated stuff, and that's the important stuff.
  • I already mentioned this elsewhere: Spring Boot is your enemy, especially if you're a beginner. It's not difficult (it simply contains some default configuration), but it's harmful in a way that it hides what it configures. As a beginner, you need to learn what happens underneath.
