spring boot 发送邮件

配置application.properties 文件

spring.mail.host=smtp.qq.comspring.mail.username=[e-mail]=xxxxxspring.mail.properties.mail.smtp.auth=truespring.mail.properties.mail.smtp.starttls.enable=truespring.mail.properties.mail.smtp.starttls.required=true

注意密码不是qq密码，也不是邮箱密码是授权码

授权码生成规则：

1.登录qq邮箱2.设置3.POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务4.开启服务（POP3、SMTP...服务）5.点击生成授权码6.发送短信7.获取授权码
