springboot2.x+mail实现邮件发送

这篇文章介绍springboot的邮件发送

由于很简单就没有分出server和imp之类，只是在controller简单写个方法进行测试。

2.application.yml
包含发送邮箱的地址，账号密码，接信地址，由于只是测试，所以都是固定写死的，如果项目中需要，可以根据自行情况进行修改。

spring:
  mail:
    host: smtp.163.com
    username: [email protected] #发送邮件邮箱地址
    password: xxxxxxxxxxxx #发送邮件邮箱密码
    protocol: smtp
    default-encoding: utf-8
    properties:
      mail:
        smtp:
          port: 465
          auth: true
          ssl:
            enable: true
          socketFactory:
            class: javax.net.ssl.SSLSocketFactory
