編寫前端代碼

<form action="${pageContext.request.contextPath}/rg" method="post">用戶名：<input type="text" name="username"><br/>密 碼：<input type="password" name="password"><br/>郵 箱：<input type="text" name="email" ><br/><input type="submit" value="注冊"><br/></form>

.xml文件配置

<servlet><servlet-name>MailWeb</servlet-name><servlet-class>com.wang.web.MailWeb</servlet-class></servlet><servlet-mapping><servlet-name>MailWeb</servlet-name><url-pattern>/rg</url-pattern></servlet-mapping>

編寫MailWeb

protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {String username = req.getParameter("username");String password = req.getParameter("password");String email = req.getParameter("email");User user=new User(username,password,email);SendMail sendMail=new SendMail(user);sendMail.start();//注冊用戶req.setAttribute("message","稍等，馬上收到郵件");req.getReq

編寫User類

package com.wang.rea;public class User{String username;String password;String email;public User(){}public User(String username, String password, String email) {this.username = username;this.password = password;this.email = email;}public String getUsername() {return username;}public String getPassword() {return password;}public String getEmail() {return email;}public void setUsername(String username) {this.username = username;}public void setPassword(String password) {this.password = password;}public void setEmail(String email) {this.email = email;}@Overridepublic String toString() {return "User{" +"username='" + username + '\'' +", password='" + password + '\'' +", email='" + email + '\'' +'}';} }

編寫線程類，控制郵件發送

// 給用戶發送郵件的郵箱private String from = "2630533885@qq.com";// 郵箱的用戶名private String username = "2630533885@qq.com";// 郵箱授權碼private String password = "rqkvkhrzhprrdiac";// 發送郵件的服務器地址，QQ服務器private String host = "smtp.qq.com";// 接收人郵箱private String to = "2630533885@qq.com";// 郵件主題private String title = "注冊郵件";private User user;public SendMail(User user){this.user=user;}@Overridepublic void run() {try {// 使用QQ郵箱時配置Properties prop = new Properties();prop.setProperty("mail.host", "smtp.qq.com"); // 設置QQ郵件服務器prop.setProperty("mail.transport.protocol", "smtp"); // 郵件發送協議prop.setProperty("mail.smtp.auth", "true"); // 需要驗證用戶名和密碼// 關于QQ郵箱，還要設置SSL加密，其他郵箱不需要MailSSLSocketFactory sf = new MailSSLSocketFactory();sf.setTrustAllHosts(true);prop.put("mail.smtp.ssl.enable", "true");prop.put("mail.smtp.ssl.socketFactory", sf);// 創建定義整個郵件程序所需的環境信息的 Session 對象，QQ才有，其他郵箱就不用了Session session = Session.getDefaultInstance(prop, new Authenticator() {@Overrideprotected PasswordAuthentication getPasswordAuthentication() {// 發件人郵箱用戶名，授權碼return new PasswordAuthentication(username, password);}});// 開啟 Session 的 debug 模式，這樣就可以查看程序發送 Email 的運行狀態session.setDebug(true);// 通過 session 得到 transport 對象Transport ts = session.getTransport();// 使用郵箱的用戶名和授權碼連上郵箱服務器ts.connect(host, username, password);// 創建郵件，寫郵件// 需要傳遞 sessionMimeMessage message = new MimeMessage(session);message.setFrom(new InternetAddress(from)); // 指明郵件的發件人message.setRecipient(Message.RecipientType.TO, new InternetAddress(user.getEmail())); // 指明郵件的收件人message.setSubject(title); // 郵件主題String info="恭喜您，注冊成功\n"+"您的賬號為："+user.getUsername()+"您的密碼是："+user.getPassword()+"您的郵箱是："+user.getEmail();message.setContent(info,"text/html;charset=utf-8");message.saveChanges();// 釋放資源//發送郵件ts.sendMessage(message,message.getAllRecipients());ts.close();}catch (Exception e){e.printStackTrace();}
