Exception in thread "main" javax.mail.AuthenticationFailedException: 454 Authentication failed, please open smtp flag first! at com.sun.mail.smtp.SMTPTransport$Authenticator.authenticate(SMTPTransport.java:826) at com.sun.mail.smtp.SMTPTransport.authenticate(SMTPTransport.java:761) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:685) at javax.mail.Service.connect(Service.java:317) at javax.mail.Service.connect(Service.java:176) at javax.mail.Service.connect(Service.java:125) at javax.mail.Transport.send0(Transport.java:194) at javax.mail.Transport.send(Transport.java:124) at zjr.amy.emil.test.MailTest.main(MailTest.java:46)
原因：没有qq邮箱没有开启smtp服务
解决方法：在QQ邮箱的设置里面，找到账户-》POP3/IMAP/SMTP选择开启POP3/SMTP服务
