Does Spring Data JPA crudrepository save method have any return value? If so what does it returns?

Question

public void registerCustomer(Customer cust)
{
customerRepo.save(cust);
}

how can i know that my data is insereted successfully in my above code?

Answer 1

Here is from CrudReporsitory.save() javadoc:

Saves a given entity. Use the returned instance for further operations as the save operation might have changed the entity instance completely.

It seems like save method returns the saved entity instance.
