該錯誤消息告訴你到底是什麼問題

造成的：org.hibernate.id.IdentifierGenerationException：此類ID必須在調用save（）之前手動分配：meinpro.entiti。孔特

的ID在你Compte類不是一個生成的值，像其他表

@Id 
private String codeCompte;

所以你需要自己設置這個值保存它。

現在看CompteEpargne和CompteCourant（其延伸Compte）構造

public CompteEpargne(String s, Date date, int i, Client c2, double taux) { 
    this.taux = taux; 
} 

public CompteEpargne(String codeCompte, Date dataCreation, double solde, Client client, Collection<Operation> operations, double taux) { 
    super(codeCompte, dataCreation, solde, client, operations); 
    this.taux = taux; 
} 

public CompteCourant(String s, Date date, int i, Client c1, double decouvert) { 
    this.decouvert = decouvert; 
} 

public CompteCourant(String codeCompte, Date dataCreation, double solde, Client client, Collection<Operation> operations, double decouvert) { 
    super(codeCompte, dataCreation, solde, client, operations); 
    this.decouvert = decouvert; 
}

每種類型的第一個構造只設置一個值，而第二個調用超構造函數，它設置所有的值（包含ID）。當您保存時，您正在使用第一個構造函數

Compte cp1=compteRep.save(new CompteCourant("c1",new Date(),9000,c1,6000)); 
Compte cp2=compteRep.save(new CompteEpargne("c2",new Date(),63000,c2,12220));

您正在調用只設置一個值的構造函數。所以你可能需要解決這些構造函數是如何設置屬性的。也許你想要做類似

public CompteEpargne(String s, Date date, int i, Client c2, double taux) { 
    this(s, date, i, c2, new ArrayList<Operation>(), taux); 
}

你在哪裏調用其他構造函數。

簡單的解決方案

  1. 你的id屬性未設置。這可能是由於DB字段未設置爲自動增量。

  2. 對於MySQL（如您在屬性文件中給出的），使用下面的示例定義POJO類。

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

我在哪裏可以實現？ – Stefan

謝謝，但它仍然無法正常工作 – Stefan

感謝網友的問題是在類孔特

@DiscriminatorColumn(name = "TYPE_CPTE,",discriminatorType= DiscriminatorType.STRING,length = 2)

在名爲= 「TYPE_CPTE，」 HHHH我不看後面的逗號TYPE_CPTE

@DiscriminatorColumn(name = "TYPE_CPTE",discriminatorType= DiscriminatorType.STRING,length = 2)
