  没什么好玩的了,最近看到好多地方有发邮件的东东,正好在看Java,就用Java写了,需要下载mail.jar和activation.jar,此外,用到我前次写的操作XML文件的一个类(上篇文章),好了,不多说了,代码贴贴,怎么用就看自己了:

//JavaMail中一些我们需要的类
//1.Properties
//
//JavaMail需要Properties来创建一个session对象,其属性值就是发送邮件的主机,如:
//
//Properties props = new Properties ();
//props.put("mail.smtp.host", "smtp.xxxx.com");//可以换上你的smtp主机名,就像你在OutLook中设置smtp主机名一样。
//props.put("mail.smtp.auth", "true"); //通过验证
//
//2.Session
//
//所有的基于JavaMail的程序都至少需要一个或全部的对话目标。
//
//Session session = Session.getInstance(props, null);
//
//3.MimeMessage
//
//信息对象将把你所发送的邮件真实的反映出来。
//
//MimeMessage msg = new MimeMessage(session);
//
//4.Transport
//
//邮件的发送是由Transport来完成的:
//
//Transport.send(msg);
