Service class for the entity

Since we opted to generate service classes for our entities, let's look at one. In the src/main/java/com/mycompany/store/service folder, you will find the entity repository service. Open ProductService.java:

@Service@Transactionalpublic class ProductService {    private final Logger log = LoggerFactory.getLogger(ProductService.class);    private final ProductRepository productRepository;    public ProductService(ProductRepository productRepository) {        this.productRepository = productRepository;    }    ...}
