Hibernate Many To Many не заполняется

0 голосов
/ 04 августа 2020

Итак, у меня есть служба бронирования, где люди заполняют форму, после того как форма отправлена, она сохраняется в базе данных. У меня две модели, чтобы добиться того же.

SpaService. java

@Entity
package com.springsec.model;

import lombok.Getter;
import lombok.Setter;
import org.springframework.format.annotation.DateTimeFormat;

import javax.persistence.*;
import java.util.Date;
import java.util.List;
import java.util.Set;

@Entity
public class Reservation {
    @Id
    @GeneratedValue(strategy= GenerationType.AUTO)
    long orderId;
    @Column(nullable = false)
    String username;
    @Column
    @ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinTable(joinColumns = @JoinColumn(name = "orderId", referencedColumnName = "orderId"),
            inverseJoinColumns = @JoinColumn(name = "serviceId", referencedColumnName = "serviceId"))
    private List<SpaService> type;
    @Column(nullable = false)
    @DateTimeFormat(pattern = "yyyy-MM-dd")
    Date date;
    @Column(nullable = false)
    String time;
    @Column
    String msg;
    @Column(nullable = false)
    int status;


    public Reservation() {
    }

    public Reservation(String username, Date date, String time, String msg, int status, Set<SpaService> type) {
        this.username = username;
        this.date = date;
        this.time = time;
        this.msg = msg;
        this.status = status;
    }

    @Override
    public String toString() {
        return "Reservation{" +
                "bookedBy='" + username + '\'' +
                ", date=" + date +
                ", time='" + time + '\'' +
                ", msg='" + msg + '\'' +
                ", status=" + status +
                '}';
    }

    public List<SpaService> getType() {
        return type;
    }

    public void setType(List<SpaService> reservation_type) {
        this.type = reservation_type;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String bookedBy) {
        this.username = bookedBy;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public String getTime() {
        return time;
    }

    public void setTime(String time) {
        this.time = time;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }
}

Бронирование. java

package com.springsec.model;

import lombok.Getter;
import lombok.Setter;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
@Getter
@Setter
public class SpaService {
    @Id
    long serviceId;
    @Column(nullable = false)
    String title;
    @Column(nullable = false)
    String description;

    public SpaService() {
    }

    public SpaService(String title, String description) {
        this.title = title;
        this.description = description;
    }

    public long getServiceId() {
        return serviceId;
    }

    public void setServiceId(long serviceId) {
        this.serviceId = serviceId;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String desc) {
        this.description = desc;
    }
}

Итак, в основном, что происходит, таблица SpaService в базе данных заполняется различными услугами, которые предлагает Spa. Как только пользователь выбирает то, что он хочет, модель типа Reservation формируется и сохраняется в базе данных.

Но по какой-то причине java получает тип Sting из внешнего интерфейса. Кроме того, когда я вручную пытался вставить в первую таблицу, объединенный столбец не заполняется.

РУЧНАЯ ПРОВЕРКА 

    @GetMapping("test")
    public String testAppointment(){
        List<SpaService> serviceList = new ArrayList<SpaService>();
        serviceList.add(new SpaService("1", "1"));
        Reservation rs = new Reservation("1",new Date(), "18:00","Hello", 0, serviceList);
        reservationService.setupReservation(rs);
        return "index";
    }

Вот мой обработчик формы отправить 

    @PostMapping("book")
    public String bookAppointment(@Valid Reservation reservation, Model model, BindingResult bindingResult){
        model.addAttribute("reservation", reservation);
        reservationService.setupReservation(reservation);
        reservation.getType().forEach(spaService -> {
            System.out.println(spaService.getTitle());
        });
        return "book";
    }
