O problema é essa linha:

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [java.util.Properties] is defined: expected single matching bean but found 2: aditionalProperties,systemProperties

Ambos implementam Properties, e por isso o spring não sabe qual deles você quer injetar.

Você vai ter que utilizar @Resource(name="namedFile") nesse caso: https://www.baeldung.com/spring-annotations-resource-inject-autowire
