从JPA解耦Spring数据

Question

我有以下接口，我想为不同的提供者通用：

public interface SurveyData {

    @Id
    Long getId();
    void setId(Long id);

    List<QuestionData> getQuestions();
    void setQuestions(List<? extends QuestionData> questions);

}

我有实体实现。

@Entity
@Table(name="sus_survey")
public class JpaSurveyData implements SurveyData {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "sus_survey_seq")
    @SequenceGenerator(name = "sus_survey_seq", sequenceName = "sus_survey_seq")
    private Long id;

    @Version
    private Long version;

    @OneToMany(mappedBy="owningSurvey")
    private List<JpaQuestionData> questions;

    //.... setters/getters
}

我想在我的beans存储库中注入实现以下接口：

@NoRepositoryBean
public interface SurveyDataRepository extends PagingAndSortingRepository<SurveyData, Long> {}

@Repository
public interface JpaSurveyDataRepository extends JpaRepository<JpaSurveyData, Long> {}

public interface SurveyDataRepository<T extends SurveyData> extends PagingAndSortingRepository<SurveyData, Long> {}

@Repository("surveyDataRepository")
public interface JpaSurveyDataRepository extends SurveyDataRepository<JpaSurveyData> {}

@Autowired
private SurveyDataRepository<SurveyData> surveyDataRepository;

No qualifying bean of type [com.xyz.SurveyDataRepository] found for dependency.

@Repository("surveyDataRepository")
public interface JpaSurveyDataRepository extends SurveyDataRepository<SurveyData> {}

结果是：

Not an managed type: interface com.xyz.SurveyData

有什么想法怎么解决？也可能少了什么。我看到的唯一解决方案是将存储库包装到自己的类中，但我希望避免这种情况。

Answer 1

我不太确定我是否理解你的问题。如果我没有的话很抱歉。

这就是你想要的吗？您有一个接口（或抽象类）surveydata和类JPASURVeydata来实现它。
您希望有一个接口A，带有surveydata和一些存储库来扩展A。

如果我是对的，这就是我的工作解决方案：

@NoRepositoryBean
public interface AbstractSurveyDataRepository<T extends SurveyData, ID extends Serializable> extends JpaRepository<T, ID> {
  T findOneBySomeId(Long someId); // you can add some common function here.
}

public interface JPASurveyDataRepository extends AbstractSurveyDataRepository<JPASurveyData, Long> {
    JPASurveyData findOneBySomeField(Long someField);
}
