Spring Boot: java.lang.StackOverflowError

Assume that I have two entities:

Hotel (Parent) --> User (Child)

Every row in table user_master have several child rows which is related to the hotel_master.

I want to delete specific rows in Hotel which means I have to delete the related rows in User first. While I'm trying to delete Hotel, I get error because I have to delete data in User first.

Here down is my code:

Entity

public class Hotel {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer hotelId;
    private String hotelName;
    private String city;

    @JsonManagedReference
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "hotel")
    private Set<User> users;

}

public class User {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer userId;
    private String userName;
    private String email;
    private String password;

    @JsonBackReference
    @ManyToOne(targetEntity = Hotel.class)
    @JoinColumn(name = "hotelId")
    private Hotel hotel;

}

ServiceImpl

@Override
public void deleteHotel(Integer hotelId) {
    Hotel hotel = hotelRepo.findById(hotelId).get();
    for (User user : hotel.getUsers()) {
        userRepo.deleteById(user.getUserId());
    }
    hotelRepo.delete(hotel);
}

Controller

@RequestMapping(value = "/{hotelId}", method = RequestMethod.DELETE)
public void deleteHotel(@PathVariable("hotelId") Integer hotelId) {
    hotelService.deleteHotel(hotelId);
}

Error
