강의로 배운 jpa말고 mysql로 임의로 바꾸는 과정에서 실수했다.

generateEmailCheckToken함수의 사용위치와 sql문에 파라미터를 누락해서 DB에 저장 되지 않는 실수가 있었다.

public Account processNewAccount(SignUpForm signUpForm) {
    Account newAccount = saveNewAccount(signUpForm);
    // newAccount.generateEmailCheckToken(); //UUID
    sendSignUpConfirmEmail(newAccount);
    return newAccount;
}

class AccountSQL {
    public String createAccount(@Param("SignUpForm") Account account) {
        return new SQL() {{
            INSERT_INTO("ACCOUNT")
            VALUES("EMAIL, NICKNAME, PASSWORD, JOINEDAT",
                    "#{SignUpForm.email}, #{SignUpForm.nickname}, #{SignUpForm.password}, NOW()")
        }}
    }

==>

private Account saveNewAccount(@Valid SignUpForm signUpForm) {
    Account account = Account.builder()
            .email(signUpForm.getEmail())
            .nickname(signUpForm.getNickname())
            .password(passwordEncoder.encode(signUpForm.getPassword()))
            .build();
    account.generateEmailCheckToken(); // UUID
    accountRepository.createAccount(account);
    return accountRepository.findByEmail(signUpForm.getEmail());
}

class AccountSQL {
    public String createAccount(@Param("SignUpForm") Account account) {
        return new SQL() {{
            INSERT_INTO("ACCOUNT")
            VALUES("EMAIL, NICKNAME, PASSWORD, EMAILCHECKTOKEN, JOINEDAT, EMAILCHECKTOKENGENERATEDAT",
                    "#{SignUpForm.email}, #{SignUpForm.nickname}, #{SignUpForm.password}, " +
                            "#{SignUpForm.emailCheckToken}, NOW(), #{SignUpForm.emailCheckTokenGeneratedAt}")
        }}
    }
