使用Java Mail API来发送邮件也很容易实现，但是最近公司一个同事封装的邮件API实在让我无法接受，于是便打算改用Spring Mail API来发送邮件，顺便记录下这篇文章。
【Spring Mail API】
Spring Mail API都在org.springframework.mail及其子包org.springframework.mail.javamail中封装，且只提供了邮件发送的封装。
SimpleMailMessage: 对邮件的一个简单封装，只能用于表示一个纯文本的邮件，也不能包含附件等。
JavaMailSenderImpl: 邮件发送器，主要提供了邮件发送接口、透明创建Java Mail的MimeMessage、及邮件发送的配置(如:host/port/username/password...)。
MimeMailMessage、MimeMessageHelper：对MimeMessage进行了封装。Spring还提供了一个回调接口MimeMessagePreparator, 用于准备JavaMail的MIME信件

org.springframework.mail.javamail.MimeMessageHelper是处理JavaMail邮件常用的顺手组件之一。它可以让你摆脱繁复的javax.mail.internetAPI类

3.发送嵌套图片的邮件
Email允许添加附件，也允许在multipart信件中内嵌资源。内嵌资源可能是你在信件中希望使用的图像，或者样式表，但是又不想把它们作为附件。
