How to get different parameters for different APIs like mentioned below

I need to get different parameters in response for 2 different APIs getAlland getbyID. Now I get the same result -second json for both APIs.

I want to get 1st json in reponse of api getALL without the one-to-many relation and I want to get 2nd json in reponse of api getbyid with one-to-many relation

First JSON Response: 

    {
     "id":2,
     "itemName":"book",

    }

Second JSON Response:

      {
     "id":2,
     "itemName":"book",
     "owner":
        {
            "id":1,
            "name":"John"
        }
    }

User Class

    public class User {
        public int id;
        public String name;

        @JsonBackReference
        public List<Item> userItems;
    }

Item class

    public class Item {
        public int id;
        public String itemName;

        @JsonManagedReference
        public User owner;
    }

can anyone help in this?

My suggestion is to make item class just for data transfer like:

public class ItemDTO {
 public int id;
 public String itemName;
}

Then in your controller you can do something like that:

@GetMapping('/get-all')
public ResponseEntity<ItemDTO> getAll() {
 //get Item object
 Item item = //e.g database call
 ItemDTO itemDTO = new ItemDTO(item.id, item.name);

 return ResponseEntity.ok(itemDTO);
}

@GetMapping('/get-by-id/{id}')
public ResponseEntity<Item> getAll(@PathVariable Integer id) {
 Item item = //e.g get item by id

 return ResponseEntity.ok(item);
}
