基于163实现邮箱验证，需先开启邮箱的SMTP服务，利用javax中的mail包实现对邮件的操作。

依赖文件

<dependency>
 <groupId>javax.mail</groupId>
 <artifactId>mail</artifactId>
 <version>1.4.7</version>
 </dependency>

MailUtil.java

public class MailUtil {
 public static final String FROM = "*******@163.com"; //发件人的email
 public static final String PWD = "*****"; //发件人密码--邮箱密码
 public static final String URL = "http://****"; //项目主页
 public static final int TIMELIMIT = 1000*60*60*24; //激活邮件过期时间24小时
 public static final String HOST = "smtp.163.com"; //163的smtp服务器
 public static final String SMTP = "smtp";
     //激活账号
 public static UserAuth activateMail(UserAuth user) throws Exception {
 //注册邮箱
 String email = user.getAccount();
 //当前时间戳
 Long curTime = System.currentTimeMillis();
 //激活的有效时间
 Long activateTime = curTime+TIMELIMIT;
 //激活码--用于激活邮箱账号
 String token = Md5Util.md5(email+curTime);
 user.setToken(token);
 //过期时间
 user.setTimes(activateTime);
 //发送的邮箱内容
 String content = "欢迎使用MINISCENE! 请在24小时内点击下面的链接激活帐户:"+" <a href='"+URL+"/user/activate.html?v=1.0&token="+token+"&email="+email+"'>"+URL+"/user/activate.html?v=1.0&token="+token+"&email="+email+"</a>";
 //调用发送邮箱服务
 MailUtil.sendMail(email, "MINISCENE账号激活", content);
 return user;
 }
     //找回密码
 public static int codeMail(String email,String code){
 //发送的邮箱内容
 String content = "答应我，不要轻易告诉别人验证码，并在5分钟内重置密码: 请收好您的验证码："+code+"";
 //调用发送邮箱服务
 try{
 MailUtil.sendMail(email, "密码找回", content);
 return 1;
 }catch (Exception e){
 e.printStackTrace();
 return 0;
 }
 }
     //邮件发送
 public static void sendMail(String email,String title,String content) throws Exception {
 
 Properties props = new Properties(); //加载一个配置文件
 // 使用smtp：简单邮件传输协议
 props.put("mail.smtp.host", HOST);//存储发送邮件服务器的信息
 props.put("mail.smtp.port", 465);//设置端口
 props.put("mail.smtp.auth", "true");//同时通过验证
 props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
 Session session = Session.getInstance(props);//根据属性新建一个邮件会话
 MimeMessage message = new MimeMessage(session);//由邮件会话新建一个消息对象
 message.setFrom(new InternetAddress(FROM));//设置发件人的地址
 message.setRecipient(Message.RecipientType.CC, new InternetAddress(FROM)); //抄送
 message.setRecipient(Message.RecipientType.TO, new InternetAddress(email));//设置收件人,并设置其接收类型为TO
 message.setSubject(title);//设置标题
 //设置信件内容
 message.setContent(content, "text/html;charset=gbk"); //发送HTML邮件
 message.setSentDate(new Date());//设置发信时间
 message.saveChanges();//存储邮件信息
 //发送邮件
 Transport transport = session.getTransport(SMTP);
 transport.connect(FROM, PWD);
 transport.sendMessage(message, message.getAllRecipients());//发送邮件,其中第二个参数是所有已设好的收件人地址
 transport.close();
 }
 }

生成token的MD5加密工具：

MD5Util.java

public class Md5Util {
 //MD5加密，生成32位md5码
 public static String md5(String inStr){
 MessageDigest StrMD5 = null;
 try{
 StrMD5 = MessageDigest.getInstance("MD5");
 }catch (Exception e){
 e.printStackTrace(); 
 return ""; 
 } 
 char[] charArray = inStr.toCharArray(); 
 byte[] byteArray = new byte[charArray.length]; 
 for (int i = 0; i < charArray.length; i++)
 byteArray[i] = (byte) charArray[i];
 byte[] md5Bytes = StrMD5.digest(byteArray);
 StringBuffer hexValue = new StringBuffer(); 
 for (int i = 0; i < md5Bytes.length; i++){
 int val = ((int) md5Bytes[i]) & 0xff;
 if (val < 16)
 hexValue.append("0");
 hexValue.append(Integer.toHexString(val));
 } 
 return hexValue.toString(); 
 }
 }
