기본적인 maven dependency추가 후 @Autowired했음
문제해결
@Bean으로 다음과 같이 protocol, host, port 지정 해줌
@Bean
public JavaMailSenderImpl mailSender() {
JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
javaMailSender.setProtocol("smtp");
javaMailSender.setHost("127.0.0.1");
javaMailSender.setPort(25);
return javaMailSender;
