    @Pattern(regexp = "(?=.*?[a-z](?=.*?[A-Z])(?=.*?[~!@#$%^&*()_+-=])[a-zA-Z~!@#$%^&*()_+-=]{8,}"
                , message = "비밀번호는 소문자, 대문자, 특수기호를 포함한 8글자 이상으로 작성하세요")
    private String password;
    private String name;
    private String gender;
    @Min(value = 14, message = "나이는 14세이상 입력하세요")
    @Max(value = 120, message = "120세이상은...ㅠ 죄송합니다")
    private int age;
