休眠引用不存在

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。

編輯：添加創建表的語句。

MANAGED_APPLICATION_TO_CONTACT：（這個是從Oracle SQL Developer中產生的，因爲我沒有已運行原始腳本）

CREATE TABLE "UAM"."MANAGED_APPLICATION_TO_CONTACT" 
    ( "MANAGED_APP_TO_CONTACT_ID" NUMBER(15,0) NOT NULL ENABLE, 
    "CONTACT_ID" NUMBER(15,0) NOT NULL ENABLE, 
    "MANAGED_APPLICATION_ID" NUMBER(6,0) NOT NULL ENABLE, 
    "LAST_UPDATED_BY" NUMBER, 
    "LAST_UPDATED" DATE,

    BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) 
    TABLESPACE "UAM" ;

MANAGED_APP_TO_CON_TO_STRUCT：（這是實際的腳本是用於創建表）

CREATE TABLE UAM.MANAGED_APP_TO_CON_TO_STRUCT (
    ID NUMBER NOT NULL, 
    MANAGED_APP_TO_CONTACT_ID NUMBER(15) NOT NULL,

    CONSTRAINT MAN_APP_TO_CON_TO_STRUCT_FK03 FOREIGN KEY (LAST_UPDATED_BY) REFERENCES MCT.CONTACT (CONTACT_ID) 
); 
CREATE UNIQUE INDEX UAM.MAN_APP_TO_CON_TO_STRUCT_IDX01 ON UAM.MANAGED_APP_TO_CON_TO_STRUCT (MANAGED_APP_TO_CONTACT_ID, STRUCTURE_ID);

編輯：添加完整的堆棧跟蹤。

編輯：

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

所以，事實證明，我曾在Contact實體此映射是用MANAGED_APPLICATION_TO_CONTACT作爲連接表檢索ManagedApplication記錄綁在Contact，這是導致休眠承擔對CONTACT_ID,MANAGED_APPLICATION_ID主鍵：

@ManyToMany(fetch = FetchType.LAZY) 
@JoinTable(name = "MANAGED_APPLICATION_TO_CONTACT", schema = "UAM", 
     joinColumns = {@JoinColumn(name = "CONTACT_ID", 
       referencedColumnName = "CONTACT_ID", 
       nullable = false)}, 
     inverseJoinColumns = {@JoinColumn(name = "MANAGED_APPLICATION_ID", 
       referencedColumnName = "MANAGED_APPLICATION_ID", 
       nullable = false)}) 
@OrderBy("name asc") 
public Set<ManagedApplication> getManagedApplications() { 
    return this.managedApplications; 
} 

public void setManagedApplications(final Set<ManagedApplication> managedApplications) { 
    this.managedApplications = managedApplications; 
}

爲了解決這個問題，我擺脫了這個映射，並將它變成了一個瞬態方法，它將ManagedApplication記錄從已經正確映射的managedApplicationToContacts記錄中提取出來。

@Transient 
public Set<ManagedApplication> getManagedApplications() { 
    if (this.managedApplications.isEmpty()) { 
     this.managedApplications = this.managedApplicationToContacts.stream() 
       .map(ManagedApplicationToContact::getManagedApplication) 
       .collect(Collectors.toSet()); 
    } 
    return this.managedApplications; 
}
