==== Attribute resolution mode
While creating `Feign` client beans, we resolve the values passed via the `@FeignClient` annotation. As of `4.x`, the values are being resolved eagerly. This is a good solution for most use-cases, and it also allows for AOT support.
If you need the attributes to be resolved lazily, set the `spring.cloud.openfeign.lazy-attributes-resolution` property value to `true`.
TIP: For Spring Cloud Contract test integration, lazy attribute resolution should be used.

=== AOT and Native Image Support
Spring Cloud OpenFeign supports Spring AOT transformations and native images, however, only with refresh mode disabled, Feign clients refresh disabled (default setting) and <<attribute-resolution-mode,lazy `@FeignClient` attribute resolution>> disabled (default setting).
WARNING: If you want to run Spring Cloud OpenFeign clients in AOT or native image modes, make sure to set `spring.cloud.refresh.enabled` to `false`.
TIP: If you want to run Spring Cloud OpenFeign clients in AOT or native image modes, ensure `spring.cloud.openfeign.client.refresh-enabled` has not been set to `true`.
TIP: If you want to run Spring Cloud OpenFeign clients in AOT or native image modes, ensure `spring.cloud.openfeign.lazy-attributes-resolution` has not been set to `true`.
