```Java
　　　　　Spring Boot
package com.example.demo.models;

import java.io.Serializable;
import com.example.demo.models.ItemCreate;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;


//import com.example.demo.models.ItemList;

import lombok.Data;

@Data
@Entity
@Table(name = "item")
public class ItemCreate implements Serializable {
	private static final long serialVersionUID = -6647247658748349084L;
	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private long id;

	@NotBlank
	@Size(max = 10)
	private String name;

	@NotBlank
	@Size(min = 1)
	private int price;

	@NotBlank

	private String content;
	
	public void clear() {

		price = 0;
		content = null;
	}

	
}

自分で試したこと

java.lang.Integer」を検証する制約「javax.validation.constraints.Size」のバリデーターが見つかりませんでした。 priceの構成を確認してください
と出ているのですが、どこをいじったらいいかわかりません…
