无法将DTO注入spring存储库

@Entity
@Table(name = "example_table")
public class ExampleEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String name;

    // 其他属性和方法...
}

public class ExampleDTO {
    private String name;

    // 其他属性和方法...
}

@Mapper
public interface ExampleMapper {
    ExampleMapper INSTANCE = Mappers.getMapper(ExampleMapper.class);

    ExampleEntity dtoToEntity(ExampleDTO dto);

    ExampleDTO entityToDto(ExampleEntity entity);
}

@Repository
public interface ExampleRepository extends JpaRepository<ExampleEntity, Long> {
    // 其他方法...
}

@Service
public class ExampleService {
    private final ExampleRepository exampleRepository;
    private final ExampleMapper exampleMapper;

    public ExampleService(ExampleRepository exampleRepository, ExampleMapper exampleMapper) {
        this.exampleRepository = exampleRepository;
        this.exampleMapper = exampleMapper;
    }

    public void saveExample(ExampleDTO dto) {
        ExampleEntity entity = exampleMapper.dtoToEntity(dto);
        exampleRepository.save(entity);
    }

    // 其他方法...
}
