除了javamail.我们可以用apache mail
为了简化开发，可以直接使用apache common项目的mail
官方网站为:http://commons.apache.org/email/
apache commons的email项目类的层次结构为
class java.lang.Object
class javax.mail.Authenticator
class org.apache.commons.mail.DefaultAuthenticator
class org.apache.commons.mail.ByteArrayDataSource (implements javax.activation.DataSource)
class org.apache.commons.mail.Email
class org.apache.commons.mail.MultiPartEmail
class org.apache.commons.mail.HtmlEmail
class org.apache.commons.mail.SimpleEmail
class org.apache.commons.mail.EmailAttachment
class java.lang.Throwable (implements java.io.Serializable)
class java.lang.Exception
class org.apache.commons.mail.EmailException
常用的有三种mail类型
SimpleEmail
MultiPartEmail
HtmlEmail
第一种就是最简单的邮件
第二种可以传附件
第三种为HTML邮件
调用起来比直接JavaMail要方便的多，写了一个工具类
