邮箱验证示例

Action类
设置好邮箱的一些基本内容：

/**
	 * 发送邮箱验证
	 * @throws Exception 
	 * */
	public String yanzheng() throws Exception {
		//得到某个邮箱的验证码
		Count count = new Count();
		T_user tUser = count.getbyid(emailid);
		System.out.println("tUser--"+tUser.getEmail());
		//加密验证码
		String checkcode = MD5Util.encode2hex(tUser.getValidatecode());
		
		HttpServletRequest request = ServletActionContext.getRequest();
		String path = request.getContextPath();
        String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path;
		
        //发送验证邮件
		StringBuffer sb = new StringBuffer();
		sb.append("<img src='https://passport.baidu.com/getpass/img/logo.gif'><br/>")
		.append("<b>亲爱的用户：</b><br/>")
		.append("您注册百度帐号 "+tUser.getEmail()+"，点击以下链接，即可激活该帐号：<br/>")
		    .append("<a href='"+basePath+"?email=")
			.append(tUser.getEmail())
			.append("&validateCode=")
			.append(checkcode)
			.append("'>"+basePath+"?email=")
			.append(tUser.getEmail()+"&validateCode="+checkcode)
			.append("</a><br/>")
			.append("(如果您无法点击此链接，请将它复制到浏览器地址栏后访问)<br/>")
			.append("1、为了保障您帐号的安全性，请在 48小时内完成激活，此链接将在您激活过一次后失效！<br/>")
			.append("2、请尽快完成激活，否则过期，即2013年 09月07日 09:30后百度将有权收回该帐号。");
		System.out.println(sb.toString());
		MailUtil.send(tUser.getEmail() , sb.toString());
		return SUCCESS;
	}

工具类
实现发送邮件

public class MailUtil {
	public static final String HOST = "smtp.163.com";
	public static final String PROTOCOL = "smtp";	
	public static final int PORT = 25;
	public static final String FROM = "****@163.com";
	public static final String PWD = "password";
	
	/**
	 * 获取Session
	 * @return
	 */
	private static Session getSession() {
		Properties props = new Properties();
		props.put("mail.smtp.host", HOST);//设置服务器地址
		props.put("mail.store.protocol" , PROTOCOL);//设置协议
		props.put("mail.smtp.port", PORT);//设置端口
		props.put("mail.smtp.auth" , true);
		
		Authenticator authenticator = new Authenticator() {
			protected PasswordAuthentication getPasswordAuthentication() {
				return new PasswordAuthentication(FROM, PWD);
			}
		};
		Session session = Session.getDefaultInstance(props , authenticator);
		
		return session;
	}
	
	public static void send(String toEmail , String content) {
		Session session = getSession();
		try {
            // Instantiate a message
            Message msg = new MimeMessage(session);
            //设置 发件的邮箱 及 对方邮箱中显示的 别名
			msg.setFrom(new InternetAddress(FROM,"拜拜公司"));
            InternetAddress[] address = {new InternetAddress(toEmail)};
            msg.setRecipients(Message.RecipientType.TO, address);
            msg.setSubject("账号激活邮件");
            msg.setSentDate(new Date());
            msg.setContent(content , "text/html;charset=utf-8");
            //发送邮件
            Transport.send(msg);
        }
        catch (MessagingException mex) {
            mex.printStackTrace();
        }catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}
	}
	
}
