一：导包

二：使用

1：在qq邮箱生成授权码：允许此qq可以被我们的电脑指挥发邮件

2：application.properties进行配置（并把授权码放到spring.mail.password=kytxteybnhhldiie）

 3：test进行测试（配置邮件内容）

一：导包

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId>
</dependency>

二：使用

1：在qq邮箱生成授权码：允许此qq可以被我们的电脑指挥发邮件

              

2：application.properties进行配置（并把授权码放到spring.mail.password=kytxteybnhhldiie）

#application.properties配置mail信息
spring.mail.username=2448003093@qq.com
spring.mail.password=kytxteybnhhldiie
#如果是163邮箱就改成smtp.163.com
spring.mail.host=smtp.qq.com
#开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=true

 3：test进行测试（配置邮件内容）
