Question

Connecting and giving values were very easy,but I couldn't load the csv data into oracle db

I was able to connect db and give data into db.

But couldn't load csv file which has no header files

Answer 1

Think of it as two separate tasks:

1.Read the csv file:

Create a reader class that transforms lines into entities

YourEntity createEntity(String[] line)

Using the reader process all lines to get a collection of entities corresponding to the csv file

2.Save the entity collection in your JPA repository(DB):

@Repository public interface YourRepository extends JpaRepository<YourEntity, UUID>

yourRepo.saveAll(Iterable entities)
