Commons Email aims to provide a API for sending email. It is built on top of the Java Mail API, which it aims to simplify.

Some of the mail classes that are provided are as follows:

• 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.

  说明：这个是Apache的一个开源项目，是基于另一个开源项目Java Mail上而进行封装的，使用起来更加简单方便。官网：

  首先下载jar包：commons-email-1.2.jar

  http://repo1.maven.org/maven2/org/apache/commons/commons-email/1.2/commons-email-1.2.jar

  1、先来一个简单文本邮件发送的例子：

  ?异常：开始放在测试项目中还是发送成功的，但是移到另一个项目中，抛异常了：Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream?
  查找资料有朋友也遇到过，是因为MyEclipse中系统自带的email.jar与导入的mail.jar包冲突不一致引起的，删除系统中的jar包即可：
  这里引用这位朋友的方法吧：
  用rar打开X:/Program Files/MyEclipse 6.0/myeclipse/eclipse/plugins/com.genuitec.eclipse.j2eedt.core_6.0.1.zmyeclipse601200710/data/libraryset/EE_5/javaee.jar
  ,然后删除mail,一切就OK了。
