幫我解決我的簡(jiǎn)單問(wèn)題。這是我的簡(jiǎn)單例外。public class MyException extends RuntimeException {private MyErrors error;public MyException() {}public MyException(String message) {    super(message);}public MyException(MyErrors error) {    super(error.getMessage());    this.error = error;}}    public class MyService {...    public String someMethod(String id){        Optional<Prizes> prize = Optional.ofNullable(prizesRepository.findById(id));        if(prize.isPresent()){            return prize.get().getPrize();        }        throw new MyException(ThanksGivenErrors.BadRequest);    }}這是 MyController 使用的 MyServicepublic class MyController{...@PostMapping("/prize")public ResponseEntity findPrize(@RequestParam String id) {    try {        return new ResponseEntity<>(MyService.someMethod(id), HttpStatus.OK);    } catch (MyException e) {        return new ResponseEntity<>(e.getError().getMessage(), HttpStatus.BAD_REQUEST);    }}}MyService 是一個(gè) Spring bean 和單例。我認(rèn)為如果在多線程環(huán)境中使用 MyService 并且發(fā)生許多 MyException，則 MyException 中 'error' 字段的值可能會(huì)發(fā)生變化?！癕yException(extends RuntimeException)”的字段值是“線程安全”嗎？我不認(rèn)為這會(huì)是安全的。謝謝你的教導(dǎo)。
