micronaut setups the configuration at compile time. so a lot of the configuration is through annotating classes. There are two main methods for this ConfigurationProperties/ConfigurationBuilder. ConfigurationBuilder maps properties to a factor and ConfigurationProperties maps properties onto a class object. It's the difference between wrapping a class and extending it. You can see the differences by looking at these two items listed below and the sample code that creates the thin client. It's more useful just to inject the configuration vs having to unwrap the bean. Hopefully this helps clarify things. The code is just a bit more clumsy using a wrapping class this way, but it's not too bad from my perspective.
