Добрый день не получается наладить добавление записей в ManyToMany. Вот код
Класс GameRoom
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long idGameRoom;
private String nameGameRoom;
private String dateGameRoom;
private String cityGameRoom;
private String adressGameRoom;
private String discriptionGameRoom;
private String filenameGameRoom;
private int countPeople;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "user_id")
private User user;
@ManyToMany(cascade = {
CascadeType.PERSIST,
CascadeType.MERGE
})
@JoinTable(
name = "tablegames_to_gameroom",
joinColumns = {@JoinColumn(name = "gameroom_id")},
inverseJoinColumns = {@JoinColumn(name = "tablegame_id")}
)
private Set<TableGames> tableGames = new HashSet<>();
public Set<TableGames> getTableGames() {
return tableGames;
}
public void setTableGames(Set<TableGames> tableGames) {
this.tableGames = tableGames;
}
public void addTableGames(TableGames tableGame){
this.tableGames.add(tableGame);
tableGame.getGamesRooms().add(this);
}
Класс TableGames
@Entity
public class TableGames {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long idTableGames;
private String nameTableGames;
private String discriptionTableGames;
private String filenameTableGames;
@ManyToMany(fetch = FetchType.LAZY, mappedBy = "tableGames")
private Set<GamesRoom> gamesRooms = new HashSet<>();
public Set<GamesRoom> getGamesRooms() {
return gamesRooms;
}
public void setGamesRooms(Set<GamesRoom> gamesRooms) {
this.gamesRooms = gamesRooms;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
TableGames that = (TableGames) o;
return gamesRooms.equals(that.gamesRooms);
}
Часть контроллера который пытаюсь отладить
@PostMapping("/gamerooms")
public String addRoom(
@AuthenticationPrincipal User user,
@RequestParam String nameGameRoom,
@RequestParam String dateGameRoom,
@RequestParam String cityGameRoom,
@RequestParam String adressGameRoom,
@RequestParam String discriptionGameRoom,
@RequestParam int countPeople,
@RequestParam Set<TableGames> gamesSet,
@RequestParam ("filenameGameRoom") MultipartFile filenameGameRoom,
Model model
)throws IOException {
gameRoomService.addGameRoom(user, nameGameRoom, discriptionGameRoom, countPeople, dateGameRoom, cityGameRoom, adressGameRoom, filenameGameRoom, gamesSet);
model.addAttribute("tablegames", gamesRepo.findAll());
model.addAttribute("gamesroom", gameRoomService.findAll());
return "gameroomsList";
}
Собственно логика добавления в в классе сервиса
public boolean addGameRoom(
User user,
String nameGameRoom,
String discriptionGameRoom,
int countPeople,
String dateGameRoom,
String cityGameRoom,
String adressGameRoom,
MultipartFile filenameGameRoom,
Set<TableGames> gamesSet
)throws IOException{
GamesRoom gamesRoom = new GamesRoom(
nameGameRoom,
dateGameRoom,
cityGameRoom,
adressGameRoom,
discriptionGameRoom,
user,
countPeople);
Iterator<TableGames> iterator = gamesSet.iterator();
while (iterator.hasNext()){
gamesRoom.addTableGames(iterator.next());
}
if (filenameGameRoom != null && !filenameGameRoom.getOriginalFilename().isEmpty()) {
File uploadDir = new File(uploadPath);
if (!uploadDir.exists()) {
uploadDir.mkdir();
}
String uuidFile = UUID.randomUUID().toString();
String resultFilename = uuidFile + "." + filenameGameRoom.getOriginalFilename();
filenameGameRoom.transferTo(new File(uploadPath + "/" + resultFilename));
gamesRoom.setFilenameGameRoom(resultFilename);
}
gameRoomRepo.save(gamesRoom);
return true;
}
То как я передаю параметр со странице (в будущем поменяю на select пока сделал так для отладки)
<div class="form-group">
<label for="exampleFormControlSelect2">Во что играем?</label>
<#list tablegames>
<#items as game>
<div class="form-check">
<input class="form-check-input" type="checkbox" value="${game.idTableGames}" id="defaultCheck1" name="gamesSet">
<label class="form-check-label" for="defaultCheck1">
${game.nameTableGames}
</label>
</div>
</#items>
</#list>
</select>
</div>
Собственно возникающая ошибка.
This application has no explicit mapping for /error, so you are seeing this as a fallback.

Я не могу понять что я делаю не так, что и где стоит поправить?
