使用JavaMail发送邮件需要用到mail.jar和activtion.jar两个包。
该类实现了较完整的邮件发送功能,包括以HTML格式发送,添加附件和抄送人。下面是具体的代码:

String copyto = "抄送人";
-
String subject = "邮件主题";
-
String content = "邮件内容";
-
String username="用户名";
-
String password="密码";
-
String filename = "附件路径,如:F:\\笔记<a>\\struts2</a>与mvc.txt";
-
Mail.sendAndCc(smtp, from, to, copyto, subject, content, username, password, filename);
