无法将 Spring 连接到 PostgreSQL

Question

Download and install PostgreSQL. I configured everything and connected it to the IDEA Inteliji.

Sent requests, tested everything. Everything works perfectly. There is an Admin class with the name and lastname fields. For them, I also left the data in the database (example: John Johnson, etc.).

Then I don't know how to connect the class itself with the database! When adding @Table (name = "ADMIN") - throws a can't resolve table error. Project Spring, Hibernate, JPA.

Class Admin :

package com.tinychiefdelights.model;

import lombok.Setter;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import java.util.List;

@Setter
@Entity
@Table(name = "admin") // THROWS EXCEPTION!!!!!! CANNOT RESOLVE TABLE
public class Admin extends User {

    public Admin(){ // Пустой конструктор для Hibernate

    }

    public Admin(String name, String lastName){
        super(name, lastName);
    }

    // Поля
    private @Id @GeneratedValue Long id;


    // Методы
    public List<Order> getCurrentOrders(){ // Вывод списка всех заказов
        return null;
    }

    public Order getOrderInfo(){ // Вывод информации по конкретному заказу
        return null;
    }

    public void removeCook(){ // Удалить повара

    }

    public void editCook(){ // Изменить карту повара

    }
}

app.prop:

If you have done everything correctly when connecting the database to the project, no errors have been made on your part, and the field with @Table is underlined in red and gives a cann't resolve table error, then you need to:
