- 添加依赖
<!-- mail -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
- 配置
spring.mail.host: smtp.exmail.qq.com
spring.mail.username:[email protected],[email protected],[email protected]
spring.mail.password:
spring.mail.properties.mail.smtp.auth: true
# 企业qq的邮箱或者是163这类，不建议使用私人qq
- 代码实现
