spring发送邮件

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

添加springboot项目基础依赖后直接添加mail的依赖即可

application.yml

# 需要开启 smtp
spring:
  mail:
    host: smtp.qq.com
    port: 465
    username: 1783292088@qq.com
    password: dgmirqbblbjncfeh
    properties:
      mail:
        smtp:
          ssl:
            enable: true

其中主要就是配置了发送方邮件的账户和密码(密码指的是邮箱的授权码)
如下图所示
