Spring Boot Exception error

0 votes

I'm working on a Spring Boot project. I'm new and I'm getting this error.

BookStoreApplication

@SpringBootApplication
public class BookStoreApplication implements CommandLineRunner {

   public final BookRepository bookRepository;

   public BookStoreApplication(BookRepository bookRepository) {
      this.bookRepository = bookRepository;
   }

   public static void main(String[] args) {
      SpringApplication.run(BookStoreApplication.class, args);
   }

   @Override
   public void run(String... args) throws Exception {
      Book book1 = Book.builder().name("Yuzuklerin Efendisi").author("J.R.R Tolkien").price(10.0).stock(10).build();
      Book book2 = Book.builder().name("Fobi").author("Wulf Dorn").price(30.5).stock(55).build();
      Book book3 = Book.builder().name("Fısıltı").author("Becca Fitzpatrick").price(20.0).stock(26).build();

   bookRepository.saveAll(Arrays.asList(book1,book2,book3));
   }
}

My error message
