Java注册帐号邮箱激活验证实现
1.需要加入发送邮件的mail.jar:

?
2.将字符串通过MD5进行加密的工具类:
class="java">import java.io.UnsupportedEncodingException; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; /** * 创建人: zy * 创建时间: 2014年10月22日 下午2:36:19 * 类描述:将字符串进行加密的工具类 */ public class MD5Util { /** * 将源字符串通过MD5进行加密为字节数组 * @param source * @return */ public static byte[] encodeToBytes(String source) { byte[] result = null; try { MessageDigest md = MessageDigest.getInstance("MD5"); md.reset();//重置 md.update(source.getBytes("UTF-8"));//添加需要加密的源 result = md.digest();//加密 } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return result; } /** * 将源字符串通过MD5加密成32位16进制数 * @param source * @return */ public static String encodeToHex(String source) { byte[] data = encodeToBytes(source);//先加密为字节数组 StringBuffer hexSb = new StringBuffer(); for (int i = 0; i < data.length; i++) { String hex = Integer.toHexString(0xff & data[i]); if (hex.length() == 1) { hexSb.append("0"); } hexSb.append(hex); } return hexSb.toString(); } /** * 验证字符串是否匹配 * @param unknown 待验证的字符串 * @param okHex 使用MD5加密后的16进制字符串 * @return */ public static boolean validate(String unknown , String okHex) { return okHex.equals(encodeToHex(unknown)); } }

3.发送邮件的工具类:
import java.util.Date; import java.util.Properties; import javax.mail.Authenticator; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; /** * 创建人: zy * 创建时间: 2014年10月22日 下午3:04:11 * 类描述:发送邮件工具类 */ public class SendMailUtil { public static final String HOST = "smtp.163.com"; public static final String PROTOCOL = "smtp"; public static final int PORT = 25; public static final String SENDER = "***@163.com";//此处需要与host相同的网站 public static final String SENDERPWD = "********"; /** * 获取用于发送邮件的Session * @return */ public 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() { @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(SENDER, SENDERPWD); } }; Session session = Session.getDefaultInstance(props,authenticator); return session; } /** * 发送邮件 * @param receiver * @param content */ public static void send(String receiver, String content) { Session session = getSession(); try { System.out.println("-------开始发送-------"); Message msg = new MimeMessage(session); //设置message属性 msg.setFrom(new InternetAddress(SENDER)); InternetAddress[] addrs = {new InternetAddress(receiver)}; msg.setRecipients(Message.RecipientType.TO, addrs); msg.setSubject("开心网-帐号激活"); msg.setSentDate(new Date()); msg.setContent(content,"text/html;charset=utf-8"); //开始发送 Transport.send(msg); System.out.println("-------发送完成-------"); } catch (AddressException e) { e.printStackTrace(); } catch (MessagingException e) { e.printStackTrace(); } } }
?
?4.发送邮件的Servlet或Action:
User user = userDao.getUser(); if (user != null && user.getQybj() != 1) { String email = user.getEmail(); StringBuffer content = new StringBuffer("<h2>请点击下面的链接激活帐号,链接只能使用一次,请尽快激活!</h2>"); String nameMd5 = MD5Util.encodeToHex(user.getUsername()+"审核通过");//创建加密字符串 content.append("<a style='font-size:16px;' href='http://localhost:8080/czfc/register.reg?doType=activate&") .append("email=" + email + "&name=" + nameMd5 +"'>") .append("http://localhost:8080/czfc/register.reg?doType=activate&") .append("email=" + email + "&name=" + nameMd5 + "</a><br/><br/>") .append("<span style='color:blue;font-size:20px;font-weight:bold;'>———浙江常山欢迎您!<span>"); SendMailUtil.send(email, content.toString());//开始发送邮件 }
?
5.点击链接验证的Servlet或Action:
String userName = request.getParameter("name"); String email = request.getParameter("email"); UserPostDao userDao = new UserPostDao(); User user = userDao.getUserByEmail(email); if (user == null) { destination = "/register/activeFail.jsp"; request.setAttribute("msg", "链接错误"); } else { String userNameMd5 = MD5Util.encodeToHex(user.getUsername()+"审核通过"); if (!(userName.equals(userNameMd5)) { request.setAttribute("msg", "链接错误"); destination = "/register/activeFail.jsp"; } else { boolean done = userDao.updateUserStatusByEmail(email, 1); if (done) { request.setAttribute("userId", user.getUserid()); request.setAttribute("userName", user.getUsername()); destination = "/register/activeSuccess.jsp"; } else { request.setAttribute("msg", "激活出错"); destination = "/register/activeFail.jsp"; } } }
