spring:
  datasource:
    url: jdbc:mysql://localhost:3306/mydatabase
    username: root
    password: password
    driver-class-name: com.mysql.jdbc.Driver

@Entity
@Table(name = "user")

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String name;

    // getters and setters
}

public interface UserRepository extends JpaRepository<User, Long> {
    List<User> findByName(String name);
}

@Service
public class UserService {
    @Autowired
    private UserRepository userRepository;

    public List<User> getUsersByName(String name) {
