我得到嘗試部署使用Hibernate的應用程序時出現以下錯誤主鍵:休眠引用不存在
外鍵(FK2e496501ee5lgk3viylwiicsa:MANAGED_APP_TO_CON_TO_SRUCT [MANAGED_APP_TO_CONTACT_ID]))必須具有相同數量作爲被引用的主鍵(MANAGED_APPLICATION_TO_CONTACT [CONTACT_ID,MANAGED_APPLICATION_ID])
但列的我不知道按什麼鍵休眠這裏引用。正如您從Oracle SQL Developer生成的模型中可以看到的那樣,CONTACT_ID, MANAGED_APPLICATION_ID
上沒有複合主鍵。 MANAGED_APPLICATION_TO_CONTACT
的主鍵位於已排序的列MANAGED_APP_TO_CONTACT_ID
上,該列是外鍵中引用的列。
所以,我認爲,導致這一問題就在於我的實體JPA映射的地方。下面是相關實體(請注意,我選擇發佈完整的實體,而不是一個最小的例子,如果問題在於地方,我不會在我的實體期待):
ManagedApplicationToContact:
@Entity
@Table(name = "MANAGED_APPLICATION_TO_CONTACT", schema = "UAM")
public class ManagedApplicationToContact implements java.io.Serializable {
private Long managedAppToContactId;
private ManagedApplication managedApplication;
private Contact contact;
private Long lastUpdatedBy;
private Date lastUpdated;
public ManagedApplicationToContact() {
}
public ManagedApplicationToContact(final ManagedApplication managedApplication, final Contact contact, final Long lastUpdatedBy, final Date lastUpdated) {
this.managedApplication = managedApplication;
this.contact = contact;
this.lastUpdatedBy = lastUpdatedBy;
this.lastUpdated = lastUpdated;
}
@SequenceGenerator(name = "generator", sequenceName = "UAM.SEQ_MANAGED_APP_TO_CONTACT", initialValue = 0, allocationSize = 1)
@Id
@GeneratedValue(strategy = SEQUENCE, generator = "generator")
@Column(name = "MANAGED_APP_TO_CONTACT_ID", unique = true, nullable = false, precision = 15, scale = 0)
public Long getManagedAppToContactId() {
return this.managedAppToContactId;
}
public void setManagedAppToContactId(final Long managedAppToContactId) {
this.managedAppToContactId = managedAppToContactId;
}
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "MANAGED_APPLICATION_ID", nullable = false)
public ManagedApplication getManagedApplication() {
return this.managedApplication;
}
public void setManagedApplication(final ManagedApplication managedApplication) {
this.managedApplication = managedApplication;
}
@Column(name = "LAST_UPDATED_BY", nullable = false, precision = 15, scale = 0)
public Long getLastUpdatedBy() {
return this.lastUpdatedBy;
}
public void setLastUpdatedBy(final Long lastUpdatedBy) {
this.lastUpdatedBy = lastUpdatedBy;
}
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "LAST_UPDATED", length = 7)
public Date getLastUpdated() {
return this.lastUpdated;
}
public void setLastUpdated(final Date lastUpdated) {
this.lastUpdated = lastUpdated;
}
@ManyToOne
@JoinColumn(name= "CONTACT_ID", referencedColumnName = "CONTACT_ID", nullable = false)
public Contact getContact() {
return contact;
}
public void setContact(final Contact contact) {
this.contact = contact;
}
}
ManagedAppToConToStruct:
@Entity
@Table(name = "MANAGED_APP_TO_CON_TO_STRUCT", schema = "UAM")
public class ManagedAppToConToStruct {
@SequenceGenerator(name = "generator", sequenceName = "UAM.MAN_APP_TO_CON_TO_STRUCT_SEQ", allocationSize = 1)
@Id
@GeneratedValue(strategy = SEQUENCE, generator = "generator")
@Column(name = "ID", unique = true, nullable = false)
private Long id;
@ManyToOne
@JoinColumn(name= "MANAGED_APP_TO_CONTACT_ID", referencedColumnName = "MANAGED_APP_TO_CONTACT_ID", nullable = false)
private ManagedApplicationToContact managedApplicationToContact;
@ManyToOne
@JoinColumn(name="STRUCTURE_ID", nullable = false)
private Structure structure;
@Column(name = "LAST_UPDATED")
private LocalDateTime lastUpdated;
@Column(name = "LAST_UPDATED_BY")
@Basic
private Long lastUpdatedBy;
public Long getId() {
return id;
}
public void setId(final Long id) {
this.id = id;
}
public ManagedApplicationToContact getManagedApplicationToContact() {
return managedApplicationToContact;
}
public void setManagedApplicationToContact(final ManagedApplicationToContact managedApplicationToContact) {
this.managedApplicationToContact = managedApplicationToContact;
}
public Structure getStructure() {
return structure;
}
public void setStructure(final Structure structure) {
this.structure = structure;
}
public LocalDateTime getLastUpdated() {
return lastUpdated;
}
public void setLastUpdated(final LocalDateTime lastUpdated) {
this.lastUpdated = lastUpdated;
}
public Long getLastUpdatedBy() {
return lastUpdatedBy;
}
public void setLastUpdatedBy(final Long lastUpdatedBy) {
this.lastUpdatedBy = lastUpdatedBy;
}
}
我甚至用過的IntelliJ IDE內置的實體生成功能建立在t這些實體他數據庫模式,並且它產生了相同的映射。我爲我的項目添加了一個Hibernate JPA構面,IntelliJ指出所有的映射都是正確的 - 所以我在這裏嚴重受難了。

也想指出,ManagedApplicationToContact
實體被添加ManagedAppToConToStruct
前工作完全正常。
您能否提供堆棧跟蹤的完整例外而不是唯一的例外消息?查看鏈中的哪個組件可以準確地發現此錯誤可能很有趣。另外:生成SQL創建語句而不是可視化圖表可能會更好。你需要對涉及的內容進行最少解釋的觀點。 – Gimby
@Gimby添加stacktrace並創建語句 –
通常情況下,您不應該在'SequenceGenerator'中重複使用該名稱,但這只是一個額外的問題,您稍後可能會遇到。這不是你目前的問題。我仍然期待看到缺少的東西。其他問題包括'JoinColumn'中的'referencedColumnName'應該在另一端具有字段的名稱,而不是列的sql-name。 – coladict
