ページの作成

ページの作成

親となるページを選択してください。

ページは必ず何かしらの親ページに紐づきます。
親ページに紐づくページを子ページといいます。
例: 親=スポーツ, 子1=サッカー, 子2=野球

子ページを親ページとして更に子ページを作成することも可能です。
例: 親=サッカー, 子=サッカーのルール

親ページはいつでも変更することが可能なのでとりあえず作ってみましょう!

10. 【Spring】@Entityアノテーションとは

本稿はSpringFrameworkの@Entityについて説明します。

@Entityとは

Entityアノテーションを付与したクラスは自クラスがEntityであることを示します。

以下、Entityアノテーションの実装例です。

package com.example.demo.entity;

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

@Entity
@Table(name="user")
public class User {
    
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column
    private long id;
    
    @Column(length=50, nullable = false)
    private String name;

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}
