【问题描述】：

我收到一个无效的标识符错误，但仅限于休眠状态。如果我从休眠日志复制查询并在我的 SQL 客户端上运行它，它就像一个魅力。

用户.java

@Entity
@Table(name = "MCI_USER", schema = Constantes.DB_SCHEMA)
@Inheritance(strategy = InheritanceType.JOINED)
public class User implements Entidade<Integer>, Serializable{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "ID")
    private Integer id;

    @Column(name = "NOME")
    private String nome;

    @Column(name = "EMAIL")
    private String email;

    @Column(name = "NUIT")
    private String nuit;

    @Column(name = "ATUALIZADOEM")
    private LocalDate atualizadoEm;

    @ManyToOne
    @JoinColumn(name = "ATUALIZADOPOR")
    private Usuario atualizadoPor;

    @Column(name = "CRIADOEM")
    private LocalDate criadoEm;

    @ManyToOne
    @JoinColumn(name = "CRIADOPOR")
    private Usuario criadoPor;

    //getters and setters

Usuario.java:

@Entity
@Table(name = "Usuario", schema = Constantes.DB_SCHEMA)
public class Usuario extends User implements UserDetails {

    @Column
    private String senha;

    @Column
    private String chaveApi;

    @Column
    private boolean ativo = true;

    @OneToMany(mappedBy = "usuario", cascade = CascadeType.ALL, orphanRemoval = true)
    private List<PerfilDoUsuario> perfis = new ArrayList<>();

    @ManyToOne
    @JoinColumn(name = "IdUnidade")
    private Unidade unidade;

    @ManyToOne
    @JoinColumn(name = "idDepartamento")
    private Departamento departamento;

    //getters and setters...

创建表脚本：

CREATE TABLE mci_user
(
    Id    INTEGER generated as identity NOT NULL,
    Nome  VARCHAR(1000)    NOT NULL,
    Email VARCHAR(200)     NOT NULL,
    NUIT  CHAR(9),
    criadoPor     int,
    criadoEm      timestamp,
    atualizadoPor int,
    atualizadoEm  timestamp,

    CONSTRAINT PK_User PRIMARY KEY (Id)
);

CREATE TABLE usuario
(
    Id             INTEGER NOT NULL,
    Senha          VARCHAR(1000)    NOT NULL,
    ChaveApi       VARCHAR(32),
    Ativo          NUMBER(3)              NOT NULL,
    IdUnidade      INT,
    IdDepartamento INT,

    CONSTRAINT PK_Usuario PRIMARY KEY (Id),
    CONSTRAINT FK_Usuario_User FOREIGN KEY (Id) REFERENCES mci_user (Id),
    CONSTRAINT FK_Usuario_Unidade FOREIGN KEY (IdUnidade) REFERENCES unidade (IdUnit),
    CONSTRAINT FK_Usuario_Departamento FOREIGN KEY (IdDepartamento) REFERENCES departamento (Id)
);

使用 oracle 12c 和休眠 5

我知道已经晚了，但据我所见，它只是在 atualizadoPor 属性中失败，因为它是 Usuario 类型，并且在 Usuario 类中，您还没有定义作为主键的 id 属性

@Entity
@Table(name = "Usuario", schema = Constantes.DB_SCHEMA)
public class Usuario extends User implements UserDetails {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "ID")
    private Integer id;
