我的模特

import lombok.Data;

import javax.persistence.*;
import java.io.Serializable;
import java.math.BigDecimal;

@Data
@Entity
@Table(name = "vendeur")
public class Vendeur implements Serializable {

    private static final long serialVersionUID = 1L;

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

    @Column(name = "CODE")
    private String code;

    @Column(name = "NOM")
    private String nom;

    @Column(name = "TELEPHONE")
    private String telephone;

    @ManyToOne
    @JoinColumn(name = "ID_COMPTE")
    private Compte compte;

    @ManyToOne
    @JoinColumn(name = "ID_VEHICULE")
    private Vehicule vehicule;

    @ManyToOne
    @JoinColumn(name = "id_Type_Vente")
    private TypeDeVente typeDeVente;

    @Column(name = "MONTANT_PLAFOND")
    private BigDecimal montantPlafond;

}

类型化

import lombok.Data;

import javax.persistence.*;
import java.io.Serializable;

@Data
@Entity
@Table(name = "type_vente")
public class TypeDeVente implements Serializable {

    private static final long serialVersionUID = 1L;

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

    @Column(name = "CODE", nullable = false)
    private String code;

    @Column(name = "LIBELLE", nullable = false)
    private String libelle;

}

这是我的财产

好的,请看一下OneTo多Springbot注释,它给你一个基本的想法,你应该如何建立你的一对多/多对一的关系。

此外,typeDeVente实体还需要@OneToMany(mappedBy=“typeDeVente”)注释。
