How to substitute collection name from environment variables in spring data?

Question

Java

Actually there is a Mongolian base, it has some kind of collection.
There is an environment variable (or a string in application.properties - it doesn't matter in this case) "collections.collection1" which is equal to what.

There is this model:

@Data
@Document(collection = "${collections.collection1}")
public class MyModel {

    @Id
    private ObjectId _id;
    @Field
    private String myField
  //...

    @Override
    public boolean equals(Object o) {
        //...
    }

    @Override
    public int hashCode() {
        //...
    }
}

Actually, when I try to request something from the database, I get an error

Invalid collection name specified 'mymongodb.${collections.collection1}

those. the variable is not substituted here (for example, in RestController, such a substituted works fine).

What am I doing wrong?
