做項目用到自動發郵件功能，網上查閱很多沒有給出特別詳細的說明，需要自己去探索，做了很多彎路。
在此給大家分享1下自己的代碼：
360網盤下載地址：http://yunpan.cn/cJzDQ3gVUHBxY 訪問密碼 8221
使用時 請將Spring 配置文件里的 用戶名、密碼、郵箱服務器 還有端口 進行修改如果不是 yeah郵箱。
如果使用maven項目：
Pom.xml

如果直接導入JAR方式 ，需要引入以下JAR包

* 再去翻1下MimeMessageHelper的API,找到這樣1句話：
* supporting alternative texts, inline elements and attachments
