java Hibernate实体类保存（实体）方法不起作用

Question

我试图将数据插入我的数据库表“claim_grouping_history”。但是实体类。保存（实体）方法不起作用

claimGroupingHistoryRepository.save(claimGroupingHistory);这行不起作用，也没有日志信息

请找到我的模型课：

@Getter
@Setter
@JsonIgnoreProperties(ignoreUnknown = true)
@Entity
@JsonInclude(NON_EMPTY)
@Table(name = "claim_grouping_history")
@EqualsAndHashCode(of = "id")
public class ClaimGroupingHistory implements Serializable {

      @Id
      @GeneratedValue(strategy = GenerationType.AUTO)
      @JsonIgnore
      private Long id;


      @Column(name = "dealer_code")
      private String dealerCode;


      @OneToOne
      @JoinColumn(name = "created_by", referencedColumnName = "id", updatable = false)
      private User createdBy;


      @Column(name = "created_at", updatable = false)
      @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
      private DateTime createdAt;

      @Column(name = "last_updated_at")
      @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
      private DateTime lastModifiedAt;

}

请查找我的保存方法实现：

    @Override
  @Transactional
  public void updateClaimGroupingKeyForDealer(String dealerId, GroupingKeyResource groupingKeyResource, String userId){

      User user = userRepository.findOne(userId);
      ClaimGroupingHistory claimGroupingHistory = null;
      System.out.println("History section---> if");
      claimGroupingHistory = new ClaimGroupingHistory();
      claimGroupingHistory.setDealerCode(dealerId);
      claimGroupingHistory.setCreatedAt(new DateTime());
      claimGroupingHistory.setCreatedBy(user);
      System.out.println("History section---> if"+claimGroupingHistory.toString());
      claimGroupingHistoryRepository.save(claimGroupingHistory);

  }

请查找我的存储库类：

 public interface ClaimGroupingHistoryRepository extends PagingAndSortingRepository<ClaimGroupingHistory, Long>, JpaSpecificationExecutor<ClaimGroupingHistory> {


    @Query("SELECT c FROM ClaimGroupingHistory c WHERE c.dealerCode = :dealer")
    ArrayList<ClaimGroupingHistory> getClaimGroupingHistory(@Param("dealer") String dealer);

    @Modifying
    @Query(value = "UPDATE ClaimGroupingHistory c SET c.createdBy = :createdBy, c.lastModifiedAt = :lastModifiedAt where c.dealerCode = :dealerCode")
    void updateClaimGroupingHistory(@Param("createdBy") User lastModifiedBy,@Param("lastModifiedAt") DateTime lastModifiedAt, @Param("dealerCode") String dealerCode);



}
