I am new to Spring Boot and i face issue i cannot resolve using internet by myself. I am trying to connect application to xampp localhost database and i get this issue, I added all necessary dependencies and here is my simple code:

Main class

package com.example.kilohokla;




@SpringBootApplication
@EnableJpaRepositories("com.example.kilohokla")
@ComponentScan(basePackages = {"com.example.kilohokla"})
public class HelloApplication extends Application {
    private ConfigurableApplicationContext applicationContext;

    @Override
    public void init() throws Exception {
        applicationContext = SpringApplication.run(HelloApplication.class);
    }

    @Override
    public void start(Stage stage) throws IOException {
//      AccountsRepository accountsRepository = applicationContext.getBean(AccountsRepository.class);
        Logger logger = LogManager.getLogger(HelloApplication.class);
//
//      Accounts sampleUser = new Accounts();
//      sampleUser.setName("Sample");
//      sampleUser.setSurname("User");
//      sampleUser.setEmail("[email protected]");
//      sampleUser.setPhoneNumber("123456789");
//      sampleUser.setPassword("password");
//      sampleUser.setLogin("sample");

        // Save the sample user to the database
//      accountsRepository.save(sampleUser);
        logger.info("Applicaton has launched succesfully");

        FXMLLoader fxmlLoader = new FXMLLoader(HelloApplication.class.getResource("login-view.fxml"));

        Font.loadFont(getClass().getResourceAsStream("/com/example/kilohokla/fonts/Inter/Inter.ttf"), 32);
        Scene scene = new Scene(fxmlLoader.load());
        stage.setTitle("Kilohokla");
        stage.setScene(scene);

        stage.show();

    }

    @Override
    public void stop() throws Exception {
        applicationContext.stop();
    }

    public static void main(String[] args) {
        launch(HelloApplication.class, args);
    }

}

Repo:

@Repository
public interface AccountsRepository extends JpaRepository<Accounts, Long> {

    void save(Accounts account);
}

Entity:

@Entity
@Table(name = "accounts")
public class Accounts {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long accountID;
    @ManyToOne
    @JoinColumn(name = "permissionID")
    private Permissions permission;

    private String name;
    private String surname;
    private String email;
    private String phoneNumber;
    private String password;
    private String login;

    @ManyToOne
    @JoinColumn(name = "teamID")
    private Teams team;

Controller

@Controller
public class AccountsController {

    @Autowired
    private AccountService accountService;

    public AccountsController() {
    }

    @PostMapping("/addAccount")
    public String addAccount(Accounts account) {
        accountService.addAccount(account);
        return "redirect:/";
    }
}

Service:

@Service
public class AccountService {
    @Autowired
    private AccountsRepository accountsRepository;
    @Transactional
    public void addAccount(Accounts account) {
        accountsRepository.saveAndFlush(account);
    }
}
