Class AutowiredInstantiationArgumentsResolver

java.lang.Object
org.springframework.beans.factory.aot.AutowiredInstantiationArgumentsResolver
public final class AutowiredInstantiationArgumentsResolver extends Object
Resolver used to support the autowiring of constructors or factory methods. Typically used in AOT-processed applications as a targeted alternative to the reflection based injection.

When resolving arguments in a native image, the Constructor or Method being used must be marked with an introspection hint so that parameter annotations can be read. Full invocation hints are only required if the resolveAndInstantiate methods of this class are being used (typically to support private constructors, methods or classes).
