SpringBoot-邮件任务

   org.springframework.boot
   spring-boot-starter-mail

看它引入的依赖，可以看到 jakarta.mail

   com.sun.mail
   jakarta.mail
   1.6.4
   compile

# qq邮箱
spring.mail.username=xxxxxx@qq.com
# 刚刚生成的授权码
spring.mail.password=xxxxxxxxx
# qq邮箱的host
spring.mail.host=smtp.qq.com
#开启加密验证(qq邮箱)
spring.mail.properties.mail.smtp.ssl.enable=true

        以QQ邮箱为例，在QQ邮箱中的设置->账户->开启pop3和smtp服务

点击开启后，会验证密保，验证通过后会弹框显示授权码
