JavaMail使用小结

今天完成了基于JavaMail 1.4.1的邮件发送构件，小结如下：

1. 对JDK 6之前的JDK应在类路径中配置两个库文件：mail.jar和activation.jar。前者在JavaMail主页下载，后者在JavaBeans Activation Framework（同样在JavaMail主页上有连接）主页上下载。
2. 可以通过javax.mail.Message.setFrom接口配置发送者邮件地址，该地址不一定与此时使用的实际邮件发送服务器一致，实际结果是收件人按照javax.mail.Message.setFrom接口提供的地址回复邮件。
3. 发送纯文本邮件的代码：

   javax.mail.Message.setContent("This is a test", "text/plain");

4. 发送HTML邮件的代码：

   javax.mail.Message.setContent("This is a test", "This is a test HTML", "text/html; charset=ISO-8859-1";// ORRRRR text/html???

5. 发送带附件邮件的代码：

   MimeMessage message = new MimeMessage(mailSession);
   message.setSubject("Testing javamail with attachment");
   MimeBodyPart textPart = new MimeBodyPart();
   textPart.setContent("Check attachment", "text/html");
   MimeBodyPart attachFilePart = new MimeBodyPart();
   FileDataSource fds = new FileDataSource("SimpleMailWithAttachment.java");
   attachFilePart.setDataHandler(new DataHandler(fds));
   attachFilePart.setFileName(fds.getName());
   Multipart mp = new MimeMultipart();
   mp.addBodyPart(textPart);
   mp.addBodyPart(attachFilePart);
   message.setContent(mp);
