java - 我正在尝试运行 spring 机器人应用程序，它显示执行 DDL 时出现 CommandAcceptanceException 错误

Question

我的模型

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DeVente

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;

}

这是我的属性

server.port=8088
spring.datasource.driverClassName = com.mysql.cj.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3307/gestion_commerciale
spring.datasource.username = root
spring.datasource.password =

spring.jpa.show-sql = false
spring.jpa.hibernate.ddl-auto = update

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect


security.ignored=/**
spring.security.enabled=false
management.security.enabled=false
security.basic.enabled=false 

错误

org.hibernate.tool.schema.spi.CommandAcceptanceException:通过 JDBC 语句执行 DDL“更改表供应商添加约束 FKovj5q276gfleu04t5gfjr3ayx 外键 (id_type_vente) 引用 type_de_vente (id)”时出错

这里都是错误

请你帮帮我。 提前谢谢您

Answer 1

好的，请看一下OneToMany Springboot annotation ，它为您提供了如何建立一对多/多对一关系的基本概念。

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