springboot mappingエラー

Question

User

package com.example.konkatsu.domain;

import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data  //getterメソッド・setterメソッドをコード上に直接書かなくて済む
@NoArgsConstructor
@AllArgsConstructor
@Entity  //JPAに管理してもらう
@Table(name = "users")  //接続するテーブルを指定
public class User {

	@Id  //変数idをプライマリーキーに指定
	@GeneratedValue   //自動採番される
	private Integer userId;
    private String mail;
    private String pass;
    @ManyToOne(fetch = FetchType.LAZY)   //Usersとprofileを1対多の関係にするため@OneToManyをつけるcascade = CascadeType.ALLを設定することでUserの操作をprofileにも伝播できる
    @JoinColumn(nullable = true, name = "userId")
    private Profile profile;
}

Profile

//profileテーブルとマッピングさせる

package com.example.konkatsu.domain;

import java.sql.Date;
import java.util.List;

import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;

@Data
@NoArgsConstructor    //デフォルトコンストラクタも必要な場合
@AllArgsConstructor   //すべてのフィールドを引数に持つコンストラクタを自動生成
@Entity    //エンティティ（一単位として扱われるデータのまとまり）であることを示す。指定したクラス名がテーブルとマッピングされる
@Table(name = "profile")  //接続するテーブルを指定
@ToString(exclude = "users")   //Userクラスには対応するProfileクラスのフィールドを追加
public class Profile {
	@Id   //主キー
	@GeneratedValue   //自動採番される
	private Integer userId;
	private Integer genderId;
	private String name;
	private Date birthday;
	private Integer height;
	private Integer occupationId;
	private Integer income;
	private String text;
	private byte[] image;
	@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "profile")    //mappedBy属性に関連先でのプロパティ名を指定

	//@ManyToOne(fetch = FetchType.LAZY) 			    //@ManyToOneで多対１の関係にする
	//@JoinColumn(nullable = true, name = "userId")   //外部キーのカラム名の指定
	private List<User> users;


}

UsersとProfileを結合させて
値を表示したいのですが
次のようなエラー出てしまいます

どこを直せば良いのでしょうか？？

Answer 1

エラーメッセージにそのままが書いてありますね。

Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: com.example.konkatsu.domain.User column: user_id (should be mapped with insert="false" update="false")

User エンティティの user_id が繰り返しマッピングされているとの事

public class User {

    @Id  //変数idをプライマリーキーに指定
    @GeneratedValue   //自動採番される
    private Integer userId;
    private String mail;
    private String pass;
    @ManyToOne(fetch = FetchType.LAZY)   //Usersとprofileを1対多の関係にするため@OneToManyをつけるcascade = CascadeType.ALLを設定することでUserの操作をprofileにも伝播できる
    @JoinColumn(nullable = true, name = "userId")
    private Profile profile;
}

JoinColumn の name が userId だからですね。User 内でかぶらない違う名前を付けたうえで referencedColumnName に user_id を付けてみてはどうでしょうか。
