我正在尝试创建一个方法，它会返回一个包含6个随机数的数组，但我一直被这个问题所困扰：

There was an unexpected error (type=Bad Request, status=400).
Failed to convert value of type 'java.lang.String' to required type 'java.lang.Integer'; nested exception is java.lang.NumberFormatException: For input string: "game12"
org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.lang.Integer'; nested exception is java.lang.NumberFormatException: For input string: "game12"

这些是我的方法

@PostMapping("/game12")
public ResponseEntity<Game> shuffleNumbers(){
    List<Integer> game=new ArrayList<>();
    Integer[] shuffled= postingShuffledGame();
    game.add(shuffled[0]);
    game.add(shuffled[1]);
    game.add(shuffled[2]);
    game.add(shuffled[3]);
    game.add(shuffled[4]);
    game.add(shuffled[5]);
    Game finalGame=new Game(game,12);
    repo.save(finalGame);
    return ResponseEntity.ok().body(finalGame);
}

public Integer[] postingShuffledGame() {
    Integer[] numbers= {1,2,3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55,56,57,58,59,60};
    List<Integer> intList=Arrays.asList(numbers);
    Collections.shuffle(intList);
    intList.toArray(numbers);
    return numbers;
}

我相信问题出在这两个中的一个，但是如果这里一切正常，这是我的完整代码：https://github.com/vitoriaacarvalho/jogando-na-mega-sena/tree/main/src/main/java/com/vitoria
非常感谢所有想帮忙的人！
