java利用commons-email發送郵件並進行封裝

本例中利用commons-email發送郵件並進行封裝，支持html內容和附件；Commons Email是Apache的Commons子項目下的一個郵件客戶端組件，它是基於JavaMail的，大大簡化了郵件的收發操做。

所需jar包：commons-email-1.4.jar和mail.jar ，jar包下載地址 http://files.cnblogs.com/files/haha12/%E5%8F%91%E9%80%81%E9%82%AE%E4%BB%B6%E6%89%80%E9%9C%80jar%E5%8C%85.rar
代碼以下：
