spring-boot 使用 spring-boot-starter-mail 发送邮件

参考文档 https://docs.spring.io/spring-framework/docs/5.3.10/reference/html/integration.html#mail-usage-simple

在pom.xml文件中引入mail启动器

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

修改application.properties文件

spring.mail.host=smtp.163.com # 发送邮件的服务地址
spring.mail.username= # 发送邮件的用户名
spring.mail.password= # 发送邮件的密码

发送邮件测试类
