Question

我正在使用spring-boot-starter-data-jpa。尝试在数据库中插入数据时，该实用程序会执行而不会出现任何错误，但是数据不会保留在数据库中。我还可以在控制台上看到插入查询我不确定这里到底出了什么问题。

 @SpringBootApplication
 public class Application implements CommandLineRunner {

    @Autowired
    DataSource dataSource;

    @Autowired
    ElementDetailsRepository elementDetailsDAO;

    @Autowired
    ElementDetailsEntity elementDetailsEntity;

    @Autowired
    ElementDetailsPK elementDetailsPK;

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

    @Transactional(propagation = Propagation.NESTED)
    @Override
    public void run(String... args) throws Exception {
      for (ExcelPojo excelPojo : listOfExcelElements) {
       if (excelPojo.getRecordType().equalsIgnoreCase("Item")) {
       if (excelPojo.getMarket().equalsIgnoreCase("UK")) {
       Integer elementID = elementDetailsDAO.findDNAElementId(excelPojo.getMarket(), 992,
                                    excelPojo.getGenesisID(), "EN");
                            System.out.println("UK ITEM..." + elementID);

        int flag = elementDetailsDAO.createPIMIDAttributeValue(excelPojo.getMarket(), 1914, excelPojo.getPimID(),elementID, "EN", getCurrentTime(), getUser());
  }
  }

存储库

    @Repository
    public interface ElementDetailsRepository extends JpaRepository<ElementDetailsEntity,Integer> {

        @Query(value = QueryConstants.findElementId, nativeQuery = true)
        public Integer findDNAElementId(@Param("country_code") String country_code, @Param("config_id") int config_id,
                @Param("import_id") String import_id,@Param("language_code")String language_code);

        @Modifying
        @Query(value = QueryConstants.createPIMIDAttributeValue, nativeQuery = true)
        public int createPIMIDAttributeValue(@Param("countrycode") String countrycode, @Param("configid") int configid,
                @Param("pimid") String attribute_value, @Param("elementid") int elementId,@Param ("languageCode") String language_code,@Param("date") String date,@Param("user") String user);
    }

@Entity
@Table(name = "element_details")
public class ElementDetailsEntity extends BaseDataObject {

 private static final long serialVersionUID = -8033261173844397824L;

尝试在主类中使用注释@EnableJpaRepositories

spring-boot-starter-data-jpa插入查询不会将数据保存在数据库中
