@Document(collection = “Test”) not working in MongoRepository - Spring data - mongodb

Question

I am trying to create generic mongo repository using generics of java. I have defined repository as below.

public interface ICentroRepository<T extends Serializable, ID extends 
Serializable> extends MongoRepository<T, ID> {  
}

and I am defining document entity as below

@Document(collection = "mycollectionName")
public class SkuItem implements Serializable {

@Id
private String _id;

String title;
//Getter and Setter of _id and title
}

but it always picks collection name as serializable(a interface/class which extends T in ICentroRepository, NOT a value defined in collection of @Document. Can anyone please help me in designing my generic mongo repository ? Many Thank you in advance. :) :)

Answer 1

public interface ICentroRepository<T extends Serializable, ID extends 
Serializable> extends MongoRepository<T, ID> {  
}

to

public interface ICentroRepository extends MongoRepository<SkuItem, ID> {  
}

Answer 2

You shall create a SkuItemRepository which is generified on SkuItem , that's how Spring Data work, otherwise what shall it return if you call its findById(id) and ...?

And what is the benefit of creating a generic repository, when Spring's base repository interface is just generic. So you are just creating a marker interface which is not of any use.

Answer 3

public interface ICentroRepository<T implements Serializable, ID implements 
Serializable> extends MongoRepository<T, ID> {  
} 

I am not sure Is that right?
