采用commons-emai发送电子邮件

Jakarta Commons-Email 1.0 版本发布了。 

    Commons-Email 提供了一套更简洁的 操作 邮件的API. 

    Commons-Email 是 基于 JavaMail API 构建. 核心组建只包含很少的几个classes. 

    下面是一些其中的类的简单介绍: 

    SimpleEmail - This class is used to send basic text based emails. 

    MultiPartEmail - This class is used to send multipart messages. This allows a text message with attachments either inline or attached. 

    HtmlEmail - This class is used to send HTML formatted emails. It has all of the capabilities as MultiPartEmail allowing attachments to be easily added. It also supports embedded images. 

    EmailAttachment - This is a simple container class to allow for easy handling of attachments. It is for use with instances of MultiPartEmail and HtmlEmail. 

commons-email是apache提供的一个开源的API，是对javamail的封装，因此在使用时要将javamail.jar加到class path中，主要包括SimpleEmail,MultiPartEmail,HtmlEmail,EmailAttachment四个类。
 
SimpleEmail:发送简单的email,不能添加附件
MultiPartEmail:文本邮件，可以添加多个附件
HtmlEmail:HTML格式邮件，同时具有MultiPartEmail类所有“功能”
EmailAttchment:附件类，可以添加本地资源，也可以指定网络上资源，在发送时自动将网络上资源下载发送。
