java利用commons-email发送邮件并进行封装

本例中利用commons-email发送邮件并进行封装，支持html内容和附件；Commons Email是Apache的Commons子项目下的一个邮件客户端组件，它是基于JavaMail的，大大简化了邮件的收发操作。

所需jar包：commons-email-1.4.jar和mail.jar ，jar包下载地址 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
代码如下：
