spring boot 发送邮件-蒲公英云

配置application.properties 文件

spring.mail.host=smtp.qq.com
spring.mail.username=770960436@qq.com
spring.mail.password=xxxxx
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.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
