+==== Spring MVC Conversion Service
 Spring MVC uses a different `ConversionService` to the one used to convert values from your `application.properties` or `application.yaml` file.
 It means that `Period`, `Duration` and `DataSize` converters are not available and that `@DurationUnit` and `@DataSizeUnit` annotations will be ignored.
 
 If you want to customize the `ConversionService` used by Spring MVC, you can provide a `WebMvcConfigurer` bean with an `addFormatters` method.
 From this method you can register any converter that you like, or you can delegate to the static methods available on `ApplicationConversionService`.
