请帮帮我

错误消息告诉您确切的问题
引起：org.hibernate.id.IdentifierGenerationException：在调用save（）之前必须手动分配此类的ID：meinpro.entiti.Compte
Compte类中的id不是生成的值，就像其他表
@Id
private String codeCompte;
因此您需要在保存之前自己设置此值。
现在查看CompteEpargne和CompteCourant（扩展Compte）构造函数
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;
}
每种类型的第一个构造函数只设置一个值，而第二个构造函数调用超级构造函数，它将 all 设置为值（包括id）。保存时，您正在使用第一个构造函数
Compte cp1=compteRep.save(new CompteCourant("c1",new Date(),9000,c1,6000));
Compte cp2=compteRep.save(new CompteEpargne("c2",new Date(),63000,c2,12220));
您正在调用仅设置一个值的构造函数。所以你可能需要修复那些构造函数如何设置属性。也许你想做类似
的事情public CompteEpargne(String s, Date date, int i, Client c2, double taux) {
this(s, date, i, c2, new ArrayList<Operation>(), taux);
}
你可以调用其他构造函数。

简单解决方案
对于MySQL（正如您在“属性”文件中所提到的），请使用以下示例来定义您的POJO类。
@Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name="id", unique=true, nullable=false) public Long getId() { return this.id; }

感谢朋友，问题出在Compte类
中 @DiscriminatorColumn(name = "TYPE_CPTE,",discriminatorType= DiscriminatorType.STRING,length = 2)
在名称中= = strong>＆＃34; TYPE_CPTE，＆＃34; hhhh我在TYPE_CPTE之后看不到逗号
@DiscriminatorColumn(name = "TYPE_CPTE",discriminatorType= DiscriminatorType.STRING,length = 2)
