http://commons.apache.org/email/  到这里去看看吧  比用javax.mail 简单的多

Answer 7

那个太麻烦了，看我的
HtmlEmail email = new HtmlEmail();
email.setHostName(hostName);
// 需要邮件发送服务器验证,用户名/密码
email.setAuthentication(authName, authPass);
email.setFrom(mailFrom, sender);//在配置文件中设置
// 设置主题的字符集为GBK
email.setCharset("GBK");
//email.setCharset("UTF-8");
email.setSubject(model.getMailTitle());
email.setHtmlMsg(model.getMailContent());
email.addTo(model.getEmail(), "");//在配置文件中设置
