Hibernate does too much joins for a single query

I have an airport database that I downloaded from the mysql site (I also uploaded a photo of it here) and I made all its settings in the spring boot program, but when I want to run a simple query select f from Flight, hibernate does a lot of strange joins and it doesn't end and the outOfMemory error is shown. In the following output, a part of hibernate queries are placed, which are not all of them, and in the middle of the java.lang.OutOfMemoryError: Java heap space is shown, and the program is terminated.

I had two questions:

First of all, what is the reason for all these joins?

Second, what is the way to prevent it?

All models classes(with hibernate mappings)-you dont need to see the view folder.

You defined in your model only EAGER relations, these relations will always be join and fetch.
You should set EAGER fetch type only when the relation is required and try to maximise LAZY relations.

public class Flight extends BaseEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "flight_id", insertable = false, updatable = false)
    private int flightId;
    @ManyToOne(fetch = FetchType.EAGER, cascade = {CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinColumn(name = "from")
    private Airport fromAirport;
    @ManyToOne(fetch = FetchType.EAGER, cascade = {CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinColumn(name = "to")
    private Airport toAirport;

    @ManyToOne(fetch = FetchType.EAGER, cascade = {CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinColumn(name = "flightno", insertable = false, updatable = false)
    private FlightSchedule schedule;
    @ManyToOne(fetch = FetchType.EAGER, cascade = {CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinColumn(name = "airline_id")
    private Airline airline;
    @ManyToOne(fetch = FetchType.EAGER, cascade = {CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinColumn(name = "airplane_id")
    private Airplane airplane;
    @OneToMany(mappedBy = "flight", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    private Set<FlightLog> logs = new HashSet<>();
    @OneToMany(mappedBy = "flight", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    private Set<Booking> bookings = new HashSet<>();
}

select f from Flight will fetch Flight, Flight.Airport (EAGER), Flight.Airport.AirportGeo (EAGER), etc
