Extra column being created when I use same column name for two different tables connected through ManyToOne relationship










0















I have SpringBoot project with Spring Data. Extra column being created when I use the same column name for 2 tables mapped using ManyToOne Relation. I have Address table with column name 'id' and AddressType table with column 'id'. When I start the Spring Boot application with this, I see an extra column (address_id) created on Address table.



Address.java



package com.springtesting.model;

import lombok.Data;

import javax.persistence.*;

@Entity
@Data
@Table(name = "address")
public class Address


@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private Long id;

@Column(name = "street_name")
private String streetName;

@Column(name = "apartment")
private String apartment;

@Column(name = "city")
private String city;

@Column(name = "state")
private String state;

@Column(name = "country")
private String country;

@Column(name = "zip_code")
private String zipCode;

@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "address_type_id")
private AddressType addressType;

public Address()



public Address(String streetName, String apartment, String city, String state, String country, String zipCode, AddressType addressType)

this.streetName = streetName;
this.apartment = apartment;
this.city = city;
this.state = state;
this.country = country;
this.zipCode = zipCode;
this.addressType = addressType;




and



AddressType.java



package com.springtesting.model;

import lombok.Data;
import lombok.NonNull;

import javax.persistence.*;

@Entity
@Data
@Table(name = "address_type")
public class AddressType

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private Long id;

@Column(name = "type")
@NonNull
private String type;

public AddressType()




public AddressType(String type)





when I start the Spring Boot application, I see extra column (address_id)

          I'm not sure this will fix your issue, but try changing the @GeneratedValue(strategy = GenerationType.AUTO) to @GeneratedValue(strategy = GenerationType.IDENTITY), or give it a "native" GenericGenerator, as discussed here. Apparently GenerationType.AUTO does not play nice with MySQL from Hibernate 5+.



          A couple of other notes:



          • You probably don't want to use Lombok's @NonNull, instead just use @Column(name = "type", nullable = false). In fact if the POJO is created through the default constructor, Lombok's @NonNull wouldn't do anything anyway since it's annotated over a field.


          • You don't need the cascade = CascadeType.ALL above the AddressType since you probably don't want to accidentally update/delete/or create new AddressTypes through the Address entity. Just annotating it @ManyToOne should be enough.
