I 일반/텍스트로하여의 setContent를 변경하는 경우, 내가 얻을 : 나는 다중 부분/혼합하는의 setContent를 변경하는 경우
javax.mail.MessagingException: IOException while sending message;
nested exception is:
java.io.IOException: "text/html" DataContentHandler requires String object, was given object of type class javax.mail.internet.MimeMessage
at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1167)
, 내가 얻을 :
javax.mail.MessagingException: MIME part of type "multipart/mixed" contains object of type javax.mail.internet.MimeMessage instead of MimeMultipart
어떻게 해결할 수 있습니까? 감사.
