How can I expand wildcards in Spring properties?

Question

I am developing spring boot application and I want to inject Collections of resources like this:

@Value("${app.users-location}")
Collection<Resource> csvResources;

inside application.properties I wrote following:

app.users-location=/feed/*.csv

But it doesn't work as expected:

For that situation I expect to see Collection of 5 elements of type Resource.

How can I achieve it ?

His solution was to use Array instead of list:

@Value("${app.users-location}")
Resource[] resources;

@PostConstruct
public void init(){
    System.out.println(resources);
}

I checked it and it really works!!!
