@ConfigProperty annotation

[Snorri1986]

Why @ConfigProperty annotation does not initialize variables in a class ?
Instead, I use ConfigProvider.getConfig().getValue("system.varname", String.class)
The article below tells me that it should work.

Kindly ask you to explain in what cases better use @ConfigProperty and in what cases ConfigProvider ?
Thanks.

The @ConfigProperty annotation only works for CDI-based beans (managed by Arc): https://quarkus.io/guides/cdi-reference.

The programmatic API can be used in cases where you need to look up a configuration in a non-CDI environment or when the piece of code is not a CDI Bean.
