1、错误描述
454 Authentication failed, please open smtp flag first!Exception in thread "main" javax.mail.AuthenticationFailedExceptionat javax.mail.Service.connect(Service.java:267)at javax.mail.Service.connect(Service.java:137)at com.you.mail.model.SendMessage.sendMessage(SendMessage.java:70)at com.you.mail.model.SendMessage.main(SendMessage.java:89)
2、错误原因
今天，我写了一个发送邮件的小实例。刚开始，我用的是163邮箱进行测试，后来是用的qq邮箱测试；163邮箱是开通了SMTP服务，而qq邮箱没有开通，导致报错
3、解决办法
（1）打开QQ邮箱，开通SMTP服务；
（2）利用其它邮箱（已开通SMTP服务）来测试。
