我在使用onetomany的hibernateMap时遇到了问题。
每当我运行应用程序时，它都会自动在主键表中创建两列作为first\u name和last\u name。
我不知道到底是什么错误。这是我在springboot中Map的代码。对不起，我在 Spring 入门。
餐桌人员：

@Entity
@Table(name = "persons")
public class Persons {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "personid")
    int PersonID;

    @Column(name = "LastName")
    String LastName;

    @Column(name = "FirstName")
    String FirstName;

    @Column(name = "Address")
    String Address;

    @Column(name = "City")
    String City;

    @OneToMany(orphanRemoval = true, mappedBy = "persons", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    List<Person_detail> person_detail = new ArrayList<Person_detail>();
...................
..................
}

表格详情：

@Entity
@Table(name = "person_detail")
public class Person_detail {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    int id;
    @Column(name = "Address")
    String Address;
    @Column(name = "Designation")
    String Designation;

    @ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinColumn(name = "person_id", referencedColumnName = "personid")
    Persons persons;
...................
.............
}

我的application.properties文件：

spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

server.servlet.context-path=/testapp

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/socket
spring.datasource.username=root
spring.datasource.password=roor
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

我的mysql查询创建表：

CREATE TABLE Persons (
    PersonID int,
    LastName varchar(255),
    FirstName varchar(255),
    Address varchar(255),
    City varchar(255) 
);

CREATE TABLE Person_detail (
    id int PRIMARY key AUTO_INCREMENT,
    Address varchar(255),
    Designation varchar(50),
   person_id int,
    FOREIGN KEY (person_id) REFERENCES persons(personid)
);

所以我的数据是


当我运行springboot应用程序时，它通过改变表自动创建名和姓。
我的目标是：

2018-06-25 20:35:15.119  INFO 6576 --- [           main] org.hibernate.dialect.Dialect            : HHH000400: Using dialect: org.hibernate.dialect.MySQL5Dialect
Hibernate: create table hibernate_sequence (next_val bigint) engine=MyISAM
Hibernate: insert into hibernate_sequence values ( 1 )
Hibernate: alter table socket.persons add column first_name varchar(255)
Hibernate: alter table socket.persons add column last_name varchar(255)

运行项目后的我的表：
