хранилище полей в Service требуется компонент с именем entityManagerFactory, который не может быть найден

Question

Как я могу решить эту проблему в моем приложении Crud? Это моя ошибка

***************************
APPLICATION FAILED TO START

Description:

Field repository in com.howtodoinjava.demo.service.UtentiServiceImpl required a bean named 'entityManagerFactory' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

Это мои классы

@Configuration
@EnableTransactionManagement

    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }

        } else {
            throw new RecordNotFoundException("No employee record exist for given id");
        }
    }

        return new ResponseEntity<UtentiEntity>(entity, new HttpHeaders(), HttpStatus.OK);
