Guys, I have a property in `application.yaml` which is set like `maxRetries: ${MAX_RETRIES:3}` where `MAX_RETRIES` is set as an env var.
I'm using Spring to map the properties using `@ConfigurationProperties`. This particular variable is `UByte` and since it is kotlin, Spring can't map it.
Any clues how to convert it properly?

Thanks anyway, but this is limited to period, data size in bytes and duration. Does not apply to `UByte`

&gt;  If you need custom type conversion, you can provide a `ConversionService` bean (with a bean named `conversionService`) or custom property editors (through a `CustomEditorConfigurer` bean) or custom `Converters` (with bean definitions annotated as `@ConfigurationPropertiesBinding`).
