Hibernate/SQL SERVER java.sql.SQLException：無法將 NULL 值插入具有默認值的列

Question

擁有 Hibernate 和 SQL 服務器，當我想更新一個名為Client的實體時遇到問題。 客戶端實體具有審計字段，例如創建/更新后者的當前用戶的名稱以及這些操作發生的日期時間。 這里的問題是，當更新發生時，會拋出java.sql.SQLException ，在日志下方以獲取更多詳細信息：

請注意， IS_SUPPRIMER列是指示該列是否被刪除的審計字段（IS_SUPPRIMER=true /deleted，IS_SUPPRIMER=false/未刪除），因此我們進行了邏輯刪除而不是物理刪除。

這里奇怪的是，映射到TF_CLIENT表的客戶端實體在腳本下方有一個名為IS_SUPPRIMER的默認值列：

CREATE TABLE [dbo].[TF_CLIENT] (
    [CLT_ID] [bigint] IDENTITY(1,1) NOT NULL,
    [CLT_LIBELLE] [nvarchar](50) NOT NULL,
    [CLT_DT_OUVERTURE] [date] NOT NULL,
    [CLT_DT_FERMETURE] [date],
    [CLT_B_ACTIF] [bit] CONSTRAINT DF_TF_CLIENT_B_ACTIF DEFAULT 1 NOT NULL,
    [DATE_CREATION] [datetime2](3),
    [DATE_MODIFICATION] [datetime2](3),
    [DATE_SUPRESSION] [datetime2](3),
    [AUTEUR_CREATION] [nvarchar](100),
    [AUTEUR_MODIFICATION] [nvarchar](100),
    [AUTEUR_SUPRESSION] [nvarchar](100),
    [IS_SUPPRIMER] [bit] CONSTRAINT DF_TF_UTILISATEUR_IS_SUPPRIMER DEFAULT 0 NOT NULL
    CONSTRAINT UQ_CLT_LIBELLE UNIQUE(CLT_LIBELLE),
    CONSTRAINT PK_TF_CLIENT PRIMARY KEY CLUSTERED
(
[CLT_ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
    ) ON [PRIMARY]
    END

那么為什么更新這樣的客戶端實體需要一個已經有默認值的IS_SUPPRIMER值呢？

在審核 class 的代碼下方：

@Embeddable
@Getter
@Setter
@NoArgsConstructor
public class FieldAuditing implements Serializable {

    @Column(name = "DATE_CREATION")
    private Instant createdAt;

    @Column(name = "DATE_MODIFICATION")
    private Instant updatedAt;

    @Column(name = "DATE_SUPRESSION")
    private Instant deletedAt;

    @Column(name = "AUTEUR_CREATION", length = 100)
    private String createdBy;

    @Column(name = "AUTEUR_MODIFICATION", length = 100)
    private String updatedBy;

    @Column(name = "AUTEUR_SUPRESSION", length = 100)
    private String deletedBy;

    @Column(name = "IS_SUPPRIMER")
    private Boolean isDeleted = false;

    @PrePersist
    public void prePersist() {
        if (this.isDeleted == null)
            setIsDeleted(Boolean.FALSE);
        setCreatedAt(Instant.now());
        setCreatedBy(LoggedInUser.get());
    }

    @PreUpdate
    public void preUpdate() {
        if (this.isDeleted == null)
            setIsDeleted(Boolean.FALSE);
        setUpdatedAt(Instant.now());
        setUpdatedBy(LoggedInUser.get());
    }

}

還有客戶端實體 class：

@Entity
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@Builder
@Table(name="TF_CLIENT", schema="dbo")
public class Client implements Serializable {

    private static final long serialVersionUID = 8832848102370267801L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO, generator="native")
    @GenericGenerator(name = "native", strategy = "native")
    @Column(name = "CLT_ID", nullable = false)
    private Long id;

    @Column(name = "CLT_LIBELLE", nullable = false, length = 50, unique = true)
    private String libelle;

    @Temporal(TemporalType.DATE)
    @Column(name = "CLT_DT_OUVERTURE", nullable = false)
    private Date dateOuverture;

    @Temporal(TemporalType.DATE)
    @Column(name = "CLT_DT_FERMETURE")
    private Date dateFermeture;

    @Column(name = "CLT_B_ACTIF")
    private boolean isActif;

    @Embedded
    private FieldAuditing fieldAuditing = new FieldAuditing() ;

    @JsonIgnore
    @OneToMany
    @Builder.Default
    @JoinColumn(name="CLI_ID")
    Set<Etablissement> etablissements = Collections.emptySet();

    @JsonIgnore
    @OneToMany(cascade = { CascadeType.PERSIST, CascadeType.MERGE })
    @JoinColumn(name="CLI_ID")
    @Builder.Default
    @Setter(AccessLevel.NONE)
    Set<CodePaie> codePaies = new HashSet<>();

    @OneToMany(fetch = FetchType.EAGER, cascade = {CascadeType.ALL}, mappedBy = "client", orphanRemoval = true)
    @Builder.Default
    @Setter(AccessLevel.NONE)
    Set<ClientAction> clientActions = Sets.newHashSet();

    @OneToMany(fetch = FetchType.EAGER, cascade = {CascadeType.ALL}, mappedBy = "client", orphanRemoval = true)
    @Builder.Default
    @Setter(AccessLevel.NONE)
    Set<ClientEtat> clientEtats = Sets.newHashSet();

    public void addClientActions(Set<ClientAction> clientActions) {
        clientActions.forEach(clientAction -> clientAction.setClient(this));
        this.clientActions.addAll(clientActions);
    }

    public void addClientEtats(Set<ClientEtat> clientEtats) {
        clientEtats.forEach(etat -> etat.setClient(this));
        this.clientEtats.addAll(clientEtats);
    }

    public void addCodePaies(Set<CodePaie> codePaies) {
        codePaies.forEach(codePaie -> codePaie.setClient(this));
        this.codePaies.addAll(codePaies);
    }

    public void removeAllCodePaie() {
        codePaies.forEach(codePaie -> codePaie.setClient(null));
        this.codePaies.clear();
    }

}

最后是更新客戶端實體的代碼片段：

 private ClientDto save(ClientDto clientDto, Client client) {
        startDateShouldBeBeforeEndDate(clientDto);
        hasUniqueCodePaies(clientDto.getCodePaies());
        Client clientSaved = clientRepository.save(clientMapper.toEntity(clientDto, client));
        clientMapper.addOrRemoveClientActions(clientDto, clientSaved);
        clientMapper.addOrRemoveClientEtats(clientDto, clientSaved);
        clientRepository.save(clientSaved);
        clientDto.setId(clientSaved.getId());
        return clientDto;
    }

請您看看我的問題描述並幫助我。

我很感激任何幫助。

Answer 1

異常表明問題出在 TF_CODE_PAIE 而不是 TF_CLIENT。 我猜 TF_CODE_PAIE.IS_SUPPRIMER 沒有默認值。

Answer 2

JPA 對表的所有字段執行查詢。 因此，當您不設置isDeleted字段時，它 null 和 JPA 使用 null 值執行查詢isDeleted字段，這就是您收到錯誤的原因。

這意味着您正在嘗試在錯誤的非空字段中設置 null 值。 默認表示當您未在 sql 查詢中設置該字段時，將其設置為默認值。 用這個

@Column(name = "IS_SUPPRIMER", columnDefinition = "bit default 0")
private Boolean isDeleted;
