Generate OrderableIndentifiers.csv file

In referencedata service generate the csv file with structrue:

Mapping:

key -> referencedata.orderable_identifiers.key

productCode -> referencedata.orderables.code

Note: we should reuse what we prepared for previous file

All export data generation logic has been added in this task.

To do

Model

• create a model class for OrderableIdentifier (currently it's just a Map<String, String> field in the Orderable class)

• add @InputFile annotations on the fields in the OrderableIdentifier model class

Data

• add a method that retrieves data in accordance with the OrderableIdentifier model class

  • use OrderableRepository

  • use a native query - the necessary data is in the orderables and orderable_identifiers tables, which are connected by a relationship

• create service class for OrderableIdentifier (should import ExportableDataService)
