[스프링] Request processing failed; nested exception is org...

스프링에서, 메일관련 라이브러리를 사용하는 중 오류가 발생했다.

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;

설명 서버가, 해당 요청을 충족시키지 못하게 하는 예기치 않은 조건을 맞닥뜨렸습니다.

예외

org.springframework.web.util.NestedServletException: 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;

nested exception is:

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate). Failed messages: javax.mail.MessagingException: Could not convert socket to TLS;

nested exception is:

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate); message exceptions (1) are:

Failed message 1: javax.mail.MessagingException: Could not convert socket to TLS;

nested exception is:

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

1. 구글계정설정에 들어가서 보안수준이 낮은 앱의 액세스를 허용

2. 메일라이브러리 빈에 아래의 코드 추가

smtp.gmail.com TLSv1.2

클라이언트(브라우저)와 서버(톰캣)의 버전차이 때문에 발생할 수 있는 문제인데,

버전을 1.2로 올려주면 해결된다.

3.방화벽을 끄고 시도해보자.

2번으로 해결
