小记：生活有望穿秋水的期待，也会有意想不到的欣喜，给自己发个邮件吧（SpringBoot整合Java Mail）

身份认证失败
Caused by: javax.mail.AuthenticationFailedException: 535 Error: authentication failed
- 1.检查邮箱是否已开启客户端授权密码，以及POP3/SMTP/IMAP服务是否开启
若都已开启，那么身份认证失败的原因很有可能是密码不对，仔细检查配置文件中参数mail.auth.password= 的值是否与邮箱中配置的一致！！！
SMTP发送失败异常
Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 554 DT:SPM 163 smtp8,DMCowAAn5Ag8LvxdHlwYYw
这个问题就很坑爹了，之前一直以为是代码问题，反复的弄来弄去，最后发现，居然是网易把邮件当成了垃圾邮件没有发送出去。解决的方法也很简单就是发送邮件的时候顺便抄送一份给自己，这样就不会被当成垃圾邮件处理了…
测试控制台结果如下：
成功接收到邮件
