MailSendException: Mail server connection failed ~~~ 라는 아래와 같은 에러가 나오면 보안설정이나 , 방화벽, avast와 같은 백신으로 인하여 충돌이 나서 날 확율이 크니 백신을 끄거나 방화벽을 확인 해야한다. 이것도 안되면 (https://myaccount.google.com/lesssecureapps) 링크로가서 허용을 한다
<html />org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1. Failed messages: javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1; message exception details (1) are: Failed message 1:
<java />Request processing failed; nested exception is org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not convert socket to TLS;
is SSL false은 포트가 잘못 됬을 확률 이높다 구글은 ssl을 지원함으로 587로 바꾼다

controller(메시지를 보낸다)

String to="blue672@naver.com";
String subject = "안녕";
String body = "이야 최고";
/* html형식으로 메일을 보내고 싶은경우 setText(body,true)를 해야한다
String body = "<html>\n" + "\n" + "<head>\n" + "\n" + "</head>\n" + "\n" +

try {
System.out.println("메시지 전송시작2");
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper messageHelper = new MimeMessageHelper(message, true, "UTF-8");
messageHelper.setFrom("aoaoaoal329@gmail.com");
messageHelper.setSubject(subject); //제목
messageHelper.setTo(to); //받는이
messageHelper.setText(body); //내용
// messageHelper.setText(body,true); //html 형식으로 보내는 경우 반드시 true해야한다
mailSender.send(message);
System.out.println("메시지 전송완료");
} catch (Exception e) {
System.out.println("에러남");

}
1. avast와 같은 백신을 반드시 꺼야한다 아니면 블루스크린이 뜬다.
