        </dependency>

spring.mail.default-encoding=UTF-8
#ping smtp.qq.com
spring.mail.host=14.18.245.164
#发送者的邮箱权限密码，// 授权密码，非登录密码，QQ个人邮箱是 开启SMTP时QQ给的授权码；开启stmp时，163的授权码，目前需要自己设定。阿里云登录邮箱 登录密码可以使用
spring.mail.password=pdmlxeelgttjiiai
#端口
#spring.mail.port=25
#协议
spring.mail.protocol=smtp
#发送者的邮箱账号
spring.mail.username=1593612833@qq.com
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
#考虑到默认端口25可能在Linux上没有开通
spring.mail.port=465
spring.mail.properties.mail.smtp.socketFactory.port=465
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback=false
