我有一個完美的Java類，可以通過Gmail帳戶發送郵件。但是，我使用了推薦的SMTP設置，當我嘗試使用Office365帳戶發送電子郵件時出現錯誤。返回的錯誤是這樣的：Office365 JavaMail錯誤
例外
javax.servlet.ServletException: javax.mail.MessagingException: Could not connect to SMTP host: smtp.office365.com, port: 587;
nested exception is:
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
下面是我的代碼：
public class GmailBean {
public static final String SERVIDOR_SMTP = "smtp.office365.com";
public static final int PORTA_SERVIDOR_SMTP = 587;
private static final String CONTA_PADRAO = "[email protected]";
private static final String SENHA_CONTA_PADRAO = "xxx";
private String de;
private String para;
private String assunto;
private String mensagem;
public void enviarEmail() throws MessagingException {
FacesContext context = FacesContext.getCurrentInstance();
AutenticaUsuario autenticaUsuario = new AutenticaUsuario(GmailBean.CONTA_PADRAO, GmailBean.SENHA_CONTA_PADRAO);
Session session = Session.getInstance(this.configuracaoEmail(), autenticaUsuario);
// try{
Transport envio = null;
MimeMessage email = new MimeMessage(session);
email.setRecipient(Message.RecipientType.TO, new InternetAddress(this.para));
email.setFrom(new InternetAddress(this.de));
email.setSubject(this.assunto);
email.setContent(this.mensagem, "text/plain");
email.setSentDate(new Date());
envio = session.getTransport("smtp");
envio.connect(GmailBean.SERVIDOR_SMTP, GmailBean.CONTA_PADRAO, GmailBean.SENHA_CONTA_PADRAO);
email.saveChanges();
envio.sendMessage(email, email.getAllRecipients());
envio.close();
context.addMessage(null, new FacesMessage("Mensagem enviada com sucesso!"));
/* }
catch(AddressException ex)
{ Logger logger = Logger.getAnonymousLogger();
FacesMessage msg = new FacesMessage("Erro ao enviar mensagem "+ ex.getMessage());
logger.info("Erro ao enviar mensagem _____________"+ ex.getMessage());
}
catch(MessagingException ex)
{
Logger logger = Logger.getAnonymousLogger();
FacesMessage msg = new FacesMessage("Erro ao enviar mensagem "+ ex.getMessage());
logger.info("Erro ao enviar mensagem _____________"+ ex.getMessage());
}*/
