⚡ Spring Boot @ConfigurationProperties Tips & Tricks

Video explaining how to validate @ConfigurationProperties annotated classes, how to get nice autocompletion in the IDE and how to reuse existing configuration properties classes multiple times.

In my channel I discuss things I believe are relevant to either Java & Spring beginners, or advanced developers who want to stay up to date. Feedback is very much welcome!

This is amazing tutorial. Thanks for sharing. Can you please cover such tutorials on SpringBoot Configurations and deployment using Docker?

Very nice video! I'm trying to learn as much Spring boot as possible for a new job I got, this is very helpful

Works also with nested ConfigurationProperties, where the inner ones should not be annotated with @ConfigurationProperties. And also spring supports the mapping from .yaml files.

Great video! I use spring boot 2.2 in my tutorial so it's good so see how this worked before version 2.2.

You could do an example with Java8 Duration & FileSize so folks won't be specifying "timeout-seconds=XX" and instead "timeout=XXs"

Do you have any example for will Dependency Jar referring to its own application.properties?

HI!
How we can resolve
my.property.first
my.property.some.second ?

It seems that autocomplete doesn't work with nested properties e.g. my.custom.property
