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
