demo:

public void sendCheck() {
Random random = new Random();
String check = "";
for (int i = 0; i < 6; i++) {
check += random.nextInt(10);
}
Cookie cookie = new Cookie("check", check);
cookie.setMaxAge(3600 * 2);
cookie.setPath("/");
response.addCookie(cookie);
MailSenderInfo mailInfo = new MailSenderInfo();
mailInfo.setMailServerHost("smtp.qq.com");
mailInfo.setMailServerPort("25");
mailInfo.setValidate(true);
mailInfo.setUserName("");//发送者用户名
mailInfo.setPassword("");// 邮箱密码
mailInfo.setFromAddress("");//发送者邮箱，建议使用qq邮箱
mailInfo.setToAddress("
[email protected]");//接收者邮箱
mailInfo.setSubject("欢迎注册Mlnx论坛新用户");
mailInfo.setContent("您好！\n感谢您注册宁波Mlnx论坛用户。\n您此次注册的验证码为：" + check
+ "。如验证码无效，请按页面提示重新发送。（此验证码有效时间为2小时，逾期无效）");
// 这个类主要来发送邮件
SimpleMailSender sms = new SimpleMailSender();
sms.sendTextMail(mailInfo);// 发送文体格式
}
此外，你还需要一个mail.jar的jar包，网上能下载到。
