Refactor core documentation to make it relevant for modern Spring applications [SPR-17642]

[spring-projects-issues]

Sébastien Deleuze opened SPR-17642 and commented

Current Spring Framework core documentation is very hard to use for people developing modern Spring Boot applications. To make it easier I think we should organize it with distinct sections:

• Section about what is common to XML, JavaConfig and functional beans
• Section specific to XML
• Section specific to JavaConfig
• Section specific to functional beans (#19615)

The JavaConfig section should also be reworked to make it mostly relevant for Spring Boot application and isolate documentation not relevant for Spring Boot to make it less confusing.

We can also probably update this kind of statement since usage and best practices have evolved.

I have not the bandwidth to do that for Spring Framework 5.2, but that's probably a good candidate for Spring Framework 5.3.
