spring-projects/spring-boot

Okay, THank you @wilkinsona

Okay, following problem:
I have a more or less stand-alone software which works as a service (more or less a discord bot, but doesn't matter here)
I implemented the JPA stuff in my project.
Long story short.
All works fine.
Table will create in my database
Spring starts - all works fine....
But if I try to save something via saveSurvey.save() I'll get a nullPointerException.
The service is autowired - it works fine
The repository is null - autowired does not work.

Does someone have an Idea why?
Sorry.. Maybe it's a config issue. Have no idea and tried several things i read in several blogs / forums.

Here code snippets:

I added following before my Main

@SpringBootApplication

I added following in my main:

ConfigurableApplicationContext context = SpringApplication.run(Runner.class, args);

I have a separate config class:

@Configuration
@EntityScan(basePackages = {"de.devngs.jeeves.database.mysql.entity"} )
@EnableJpaRepositories(basePackages = {"de.devngs.jeeves.database.mysql.repository"})
public class MySqlConfig {
}

my Service

public interface SurveyService {
    List<Survey> findAll();
    Optional<Survey> findSurveyById(UUID id);
    Survey saveSurvey(Survey survey);
    void deleteSurveyById(UUID id);
    void deleteSurvey(Survey Survey);
}

my Service impl

@Service
public class SurveyServiceImpl implements SurveyService {

    @Autowired
    private SurveyRepository surveyRepository;

    @Override
    public List<Survey> findAll() {
        return surveyRepository.findAll();
    }

    @Override
    public Optional<Survey> findSurveyById(UUID id) {
        return surveyRepository.findSurveyById(id);
    }

    @Override
    public Survey saveSurvey(Survey survey) {
        surveyRepository.save(survey);
        return survey;
    }

    @Override
    public void deleteSurveyById(UUID id) {
        Optional<Survey> survey = surveyRepository.findSurveyById(id);
        survey.ifPresent(value -> surveyRepository.delete(value));
    }

    @Override
    public void deleteSurvey(Survey Survey) {
        surveyRepository.delete(Survey);
    }
}

My repo

@Repository
public interface SurveyRepository extends JpaRepository<Survey, String> {
    Optional<Survey> findSurveyById(UUID id);
}

my entity

@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@Entity(name = "survey")
@Table(name = "survey")
public class Survey {
    @Id
    @Type(type = "uuid-char")
    @Column(name = "id", updatable = false, nullable = false, length = 36)
    private UUID id;
    private String survey;
    private String options;

    public Survey(String survey, String options){
        this.id = UUID.randomUUID();
        this.survey = survey;
        this.options = options;
    }
}

my Config

spring:
  jpa:
    properties:
      hibernate:
        show_sql: false
