Hibernate. Person is not mapped-CodePudding

I just want to find all rows from the database (postgres:alpine) with Hibernate but got "not mapped" error.

Exception in thread "main" java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Person is not mapped [from Person p]

I've a lot of read about this error. So people in createQuery write incorrect name. I have right one (classname). But still get this error. Any ideas please?

Entity:

import javax.persistence.*;
import javax.persistence.Entity;
import java.io.Serializable;

@Entity
@Table(name="users")
public class Person implements Serializable {
    protected int id;
    protected String name;
    protected int age;
    protected String email;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    public int getId() {
        return id;
    }

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

    @Column(name = "name")
    public String getName() {
        return name;
    }

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

    @Column(name = "email")
    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Column(name = "age")
    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

You don't scan the correct package.

Your entity is in ch.fdsgn.models
You scan p:packagesToScan="ch.fdsgn.dao"
