我有 2 个网络服务 API。在一个 api 中，我获取一个实体并作为 SRO 返回。我是另一个 api，我收到一个 SRO，将其转换为实体并使用

sessionFactory.getCurrentSession().merge(code);

但是，我得到以下异常。请帮我找出相同的原因。

org.springframework.orm.hibernate3.HibernateOptimisticLockingFailureException: Object of class [PartnerPromoCode] with identifier [254874]: optimistic locking failed; nested exception is org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [PartnerPromoCode#254874]

这是实体 @Entity @Table(name = "partner_promo_code", catalog = "snapdeal") @NamedQueries({ @NamedQuery(name = QueryNames.GET_UNUSED_PARTNER_PROMO_CODE, query = "select p from PartnerPromoCode p where p.status=0 and p .partnerCode = :partnerCode 和 p.catalogId = :catalogId order by p.id"), @NamedQuery(name = QueryNames.GET_PARTNER_PROMO_CODE_BY_PROMO, query = "from PartnerPromoCode where partnerCode = :partnerCode and promoCode = :promoCode") }) 公共类PartnerPromoCode 实现 java.io.Serializable {

public static final Boolean STATUS_USED      = true;
public static final Boolean STATUS_NOT_USED  = false;
/**

private static final long   serialVersionUID = 7786688992136091701L;
private Integer             id;

private Date                expiry;
private Date                created;

public PartnerPromoCode() {
}

public PartnerPromoCode(String partnerCode, String promoCode) {
    this.partnerCode = partnerCode;
    this.promoCode = promoCode;
    this.status = STATUS_NOT_USED;
}

@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "id", unique = true, nullable = false)
public Integer getId() {
    return this.id;
}

public void setId(Integer id) {
    this.id = id;
}

@Column(name = "partner_code")
public String getPartnerCode() {
    return partnerCode;
}

public void setPartnerCode(String partnerCode) {
    this.partnerCode = partnerCode;
}

@Column(name = "promo_code")
public String getPromoCode() {
    return promoCode;
}

public void setPromoCode(String promoCode) {
    this.promoCode = promoCode;
}

@Column(name = "status")
public Boolean getStatus() {
    return status;
}

public void setStatus(Boolean status) {
    this.status = status;
}

@Temporal(TemporalType.TIMESTAMP)
@Column(name = "expiry", nullable = false, length = 19)
public Date getExpiry() {
    return expiry;
}

public void setExpiry(Date expiry) {
    this.expiry = expiry;
}

@Temporal(TemporalType.TIMESTAMP)
@Column(name = "created", nullable = false, length = 19)
public Date getCreated() {
    return created;
}

public void setCreated(Date created) {
    this.created = created;
}

@Version
@Column(name = "updated", nullable = false, length = 19)
public Date getUpdated() {
    return updated;
}

public void setUpdated(Date updated) {
    this.updated = updated;
}

}

我正在通过 id 获取实体并将其转换为 SRO，将其通过网络传递...然后我收到 sro，创建一个新的实体对象并设置 id 和所有其他字段，将更新的字段设置为当前时间，然后尝试通过合并实体sessionFactory.getSession().merge(obj)

因为带有注释的字段@Version的值与存储在数据库中的值不匹配（或者因为数据库中的行不再存在）。
