Class AutowiredFieldValueResolver

java.lang.Object
org.springframework.beans.factory.aot.AutowiredFieldValueResolver
public final class AutowiredFieldValueResolver extends Object
Resolver used to support the autowiring of fields. Typically used in AOT-processed applications as a targeted alternative to the AutowiredAnnotationBeanPostProcessor.

When resolving arguments in a native image, the Field being used must be marked with an introspection hint so that field annotations can be read. Full invocation hints are only required if the resolveAndSet(RegisteredBean, Object) method of this class is being used (typically to support private fields).
