通过 JDBC 语句执行 DDL Id 不是 null 时出错

Question

我正在尝试从 User_details 表到 Vehicle_details 表进行一对多映射。发生此错误。 “通过 JDBC 语句执行 DDL 时出错“alter table vehicle_detail add vehicle_id number(10,0) not null””我认为这个错误是因为生成值注释。 如何解决这个问题。

User_details.java

import javax.persistence.Entity;
import javax.persistence.Id;

import java.util.List;

import javax.persistence.*;
@Entity
@Table(name = "User_Detail")
public class UserDetails {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="user_id")
    int u_id;
    String u_name;
    String u_email;
    int mob_no;
    String gender;
    int age;
    String city;
    String State;
    int pincode;
    String address;
    String password;

    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name="fk_user_id",referencedColumnName = "user_id")
    private List<Vehicle> vehicle;

    }

车辆.java

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;

import org.hibernate.annotations.GeneratorType;

@Entity
@Table(name="Vehicle_detail")
public class Vehicle {
    
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="vehicle_id")
    private int vid;
    
    private String vname;
    private String vmodel;
    private String showroomprice;
    private String onroadprice;
    private long aadharcardno;
    private String pancardno;
    private boolean photo;
    private String employmenttypes;
    private boolean salaryslip;
    private int annualsalary;
    private boolean existingemi;
}

你只需要在 pom.xml 页面中添加 hibernate 依赖项

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
</dependency>
