问题描述

我在Websphere 8.5.5.1上使用Spring Boot 1.5.9.RELEASE ，我的jpa界面如下：

public interface RequestRepository extends JpaRepository<Request, Long> {

}

我的请求实体如下：

@Entity
public class Request {

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

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(nullable = false, name = "region_id")
    private Region region;

    @OneToOne(mappedBy = "request", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = "invoice_id", referencedColumnName = "id")
    private Invoice invoice;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(nullable = false, name = "service_type_id")
    private ServiceType serviceType;

    @Column(name = "service_type_id", insertable = false, updatable = false)
    private Long serviceTypeId;

    @Lob
    @Column(nullable = false)
    private String notes;

    @Enumerated(EnumType.STRING)
    @Column(nullable = false)
    private RequestStatusEnum status = RequestStatusEnum.NEW;

    @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
    @JoinColumn(name = "request_id")
    @OrderBy("id desc")
    private List<Attachment> attachmentsList = new ArrayList<Attachment>();

    @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinColumn(name = "request_id")
    // @OrderBy("id desc")
    private List<Action> actionsList = new ArrayList<Action>();

    @Transient
    private List<Action> actionsDisplayList = new ArrayList<Action>();

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(nullable = false, name = "creator_id")
    private User creator;

    @Temporal(TemporalType.TIMESTAMP)
    private Date dateCreated = new Date();

    private int dateCreatedHijri = DateUtil.getCurrentHijriDateAsNumber();

    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "reserved_by_user_id")
    private User reservedBy;

    @Enumerated(EnumType.STRING)
    @Column
    private InvoiceTypeEnum invoiceType = null;

    @Column
    private String crNumber;

    @Lob
    @Column
    private String companyName;

    @Column
    private String businessTypeAr;

    @Column
    private Boolean isMain;

    @Temporal(TemporalType.TIMESTAMP)
    private Date reservationDate;

    @Temporal(TemporalType.TIMESTAMP)
    private Date finishDate;

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "request", cascade = CascadeType.ALL, orphanRemoval = true)
    private List<RequestRejectReason> rejectReasonList = new ArrayList<RequestRejectReason>();

    @Transient
    private List<RejectReason> newRejectReasonList = new ArrayList<RejectReason>();

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "finished_by_user_id")
    private User finishedByUser;
    
}

在我的支持 bean 中，有时在尝试调用JpaRepository.save时，如下所示：

@Component("employeeInbox")
@Scope("session")
public class EmployeeInboxBean implements Serializable {

    private static final long serialVersionUID = 6609775672949354713L;
    
    @Autowired
    private RequestRepository requestRepository;
    
    @Transactional
    public void sendAction() {
      requestRepository.save(request);
    }
    

}

我收到以下异常：
