基于spring boot发送邮件

Spring提供了非常好用的 JavaMailSender接口实现邮件发送。只需引入依赖：

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-mail</artifactId>

</dependency>

以qq邮箱为例，在 application.properties 中加入如下配置：

spring.mail.host=smtp.qq.com

[email protected]

spring.mail.password=xxx

spring.mail.default-encoding=UTF-8

spring.mail.port=465

spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

spring.mail.properties.mail.debug=true

[email protected]

PS:

spring.mail.password=这里填写授权码

[email protected]:自己的邮箱

实现：
