[转载]使用Spring邮件抽象层发送简单邮件
<P>文章作者：shmily432685<BR><FONT size=3><FONT size=1><BR>Spring提供了一个发送电子邮件的高级抽象层，它向用户屏蔽了底层邮件系统的一些细节，同时负责低层次的代表客户端的资源处理。Spring邮件抽象层的主要包为org.springframework.mail。它包括了发送电子邮件的主要接口MailSender和 封装了简单邮件的属性如from, to,cc, subject, text的值对象叫做SimpleMailMessage。 <BR><BR> 1、我们定义一个发送邮件的接口:OrderManager.java</FONT> <BR><BR></P></FONT><P>

<P><BR> 2、我们需要对该接口进行实现的方法:OrderManagerImpl.java<BR><BR></P>

<P><BR> 到此所有的开发以结束。<BR><BR> Sring邮件抽象层的主要包是：org.springframework.mail 包。它包含叫MailSender为发送邮件的核心接口和包含简单邮件属性例如from,to,cc,subject,text叫SimpleMailMessage的值对象. 这个包也包含一个检查异常的层次，它支持一个更高级别的抽象超过低级别的邮件系统异常伴随根异常存在MailException. 请参考JavaDocs为更多的信息杂邮件异常层次。<BR><BR> Spring也支持一个MailSender的专用于JavaMail特征例如MIME消息子接口，命名为org.springframework.javamail.JavaMailerSener。它也支持一个为JavaMail MIME信息的准备回调接口，命名为org.springframework.mail.JavaMail.MimeMessagePreparator</P>
