很抱歉问这个问题。许多人可能会说有很多答案，但我的运气不好，没有一个对我有用。

这是实体类： TIMELINE ENTITY：

@Entity
@Table(name = "TIMELINE")
public class Timeline extends ChronosEntity implements HasIdAndDomain, HasIdAndOwnerUser {
private Long id;
private String name;
private int nofAsgSlotsPerDay;
private Long ownerUserId;
private User owner;
private Long domainId;
private Domain domain;

@Id
@Column(name = "TIMELINE_ID", columnDefinition = "BIGINT(15)")
@GeneratedValue
public Long getId() {
    return id;
}

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

@Column(name = "TIMELINE_NAME", unique = true)
@NotNull
public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

@Column(name = "NOF_ASG_SLOTS_PER_DAY")
public int getNofAsgSlotsPerDay() {
    return nofAsgSlotsPerDay;
}

public void setNofAsgSlotsPerDay(int nofAsgSlotsPerDay) {
    this.nofAsgSlotsPerDay = nofAsgSlotsPerDay;
}

@Column(name = "OWNER_USER_ID")
public Long getOwnerUserId() {
    return ownerUserId;
}

public void setOwnerUserId(Long ownerUserId) {
    this.ownerUserId = ownerUserId;
}

@ManyToOne
@JoinColumn(name = "OWNER_USER_ID", referencedColumnName = "USER_ID", insertable = false, updatable = false)
public User getOwner() {
    return owner;
}

public void setOwner(User owner) {
    this.owner = owner;
}

@Column(name = "DOMAIN_ID")
public Long getDomainId() {
    return domainId;
}

public void setDomainId(Long domainId) {
    this.domainId = domainId;
}

@ManyToOne
@JoinColumn(name = "DOMAIN_ID", referencedColumnName = "DOMAIN_ID", insertable = false, updatable = false)
public Domain getDomain() {
    return domain;
}

public void setDomain(Domain domain) {
    this.domain = domain;
}
}

值得一提的是，我没有使用双向关联。域实体具有主键“DOMAIN_ID”。

现在错误：

在此先感谢 \n Edit-1：域实体：

@Entity
@Table(name = "DOMAIN")
public class Domain extends ChronosEntity implements HasId, HasIdAndOwnerUser {
@Id
@Column(name = "DOMAIN_ID", columnDefinition = "BIGINT(15)")
@GeneratedValue
public Long getId() {
    return id;
}

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

@Column(name = "DOMAIN_NAME", unique = true)
@NotNull
public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

@Column(name = "OWNER_USER_ID")
public Long getOwnerUserId() {
    return ownerUserId;
}

public void setOwnerUserId(Long ownerUserId) {
    this.ownerUserId = ownerUserId;
}

@ManyToOne
@JoinColumn(name = "OWNER_USER_ID", referencedColumnName = "USER_ID", insertable = false, updatable = false, columnDefinition = "BIGINT(15)")
public User getOwner() {
    return owner;
}

@SuppressWarnings("unused")
private void setOwner(User owner) {
    this.owner = owner;
}

@Column(name = "CREATION_DATE")
@Temporal(value = TemporalType.TIMESTAMP)
@CreationTimestamp
public Date getCreationDate() {
    return creationDate;
}

public void setCreationDate(Date creationDate) {
    this.creationDate = creationDate;
}
}

Edit-2：Chronos 实体。

@MappedSuperclass
public class ChronosEntity {
private Long version;
private Long transactionId;

@Version
@Column(name="VERSION", columnDefinition="BIGINT(15)")
public Long getVersion() {
    return version;
}
public void setVersion(Long version) {
    this.version = version;
}

@Column(name="TRANSACTION_ID", columnDefinition="BIGINT(15)")
public Long getTransactionId() {
    return transactionId;
}
public void setTransactionId(Long transactionId) {
    this.transactionId = transactionId;
}
}

您还应该@OneToMany在 DOMAIN 对象中创建相反的关联。如果您不想要双向关联，可以将其保留为私有字段。

将此添加到域类：

@OneToMany(mappedBy="domain")
private List<TimeLine> timelines =  new ArrayList<>();

根据您描述问题的方式，您确实有双向关联，您只是不希望在处理域对象时更改 Timeline 对象上的内容，因此只需确保timelines是私有的并且没有 getter/setter。这将解决问题并仍然保持所需的行为。
