配置application.yml

spring:
  mail:
    host: smtpscn1.huawei.com
    port: 25
    username: pmail_AresOcean1
    password: 9KffW2_v!
    from: aresocean1@huawei.com
    to: liumeng23@huawei.com
# 设置是否需要认证，如果为true,那么用户名和密码就必须的，
# 如果设置false，可以不设置用户名和密码，当然也得看你的对接的平台是否支持无密码进行访问的。
    properties:
      mail:
        smtp:
          ssl:
            trust: smtpscn1.huawei.com
          auth: true
          # STARTTLS[1]  是对纯文本通信协议的扩展。它提供一种方式将纯文本连接升级为加密连接（TLS或SSL），而不是另外使用一个端口作加密通信
          starttls:
            enable: false
            required: true
  freemarker: #主要用于邮件模板
    allow-request-override: false
    cache: true
    check-template-location: true
    charset: UTF-8
    content-type: text/html
    expose-request-attributes: false
    expose-session-attributes: false
    expose-spring-macro-helpers: false
