郵箱驗證碼功能實現(xiàn)

在進(jìn)行實際項目的開發(fā)過程中，我們可能會遇到需要需要對用戶賬號密碼進(jìn)行找回，這時就需要我們通過郵件進(jìn)行驗證，從而對用戶信息進(jìn)行修改，下面我就將自己開發(fā)過程中的郵件發(fā)送功能簡單描述一下，供大家學(xué)習(xí)使用。

import java.util.HashMap; import java.util.Map; import java.util.Properties; public class MailSenderInfo { private String mailServerHost; //發(fā)送郵件的服務(wù)器 private String mailServerPort="587"; //發(fā)送郵件的服務(wù)器的端口 private String fromAddress; //發(fā)送者地址 private String toAddress; //接收者地址 private String username; //發(fā)送者用戶名 private String password; //發(fā)送者密碼 private boolean validate=true; //是否需要身份驗證 private String subject; //郵件主題 private String content; //郵件內(nèi)容 private Map<String, String> mailType; //郵箱類型 //得到郵件會話屬性 public Properties getProperties(){ Properties p = new Properties(); p.put("mail.smtp.host", this.mailServerHost); p.put("mail.smtp.port", this.mailServerPort); p.put("mail.smtp.auth", validate?"true":"false"); return p; } public String getMailServerHost() { return mailServerHost; } public void setMailServerHost(String mailServerHost) { this.mailServerHost = mailServerHost; } public String getMailServerPort() { return mailServerPort; } public void setMailServerPort(String mailServerPort) { this.mailServerPort = mailServerPort; } public String getFromAddress() { return fromAddress; } public void setFromAddress(String fromAddress) { this.fromAddress = fromAddress; } public String getToAddress() { return toAddress; } public void setToAddress(String toAddress) { this.toAddress = toAddress; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; this.fromAddress=username; if(username!=null&&username.length()>0){ String fromEmailExt=username.substring(username.lastIndexOf("@")+1,username.lastIndexOf(".")); this.mailServerHost=getMailType().get(fromEmailExt); } } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public boolean isValidate() { return validate; } public void setValidate(boolean validate) { this.validate = validate; } public String getSubject() { return subject; } public void setSubject(String subject) { this.subject = subject; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public Map<String, String> getMailType() { mailType=new HashMap<String, String>(); mailType.put("163","smtp.163.com"); mailType.put("139","smtp.139.com"); mailType.put("126","smtp.126.com"); mailType.put("qq", "smtp.qq.com"); mailType.put("sohu", "smtp.sohu.com"); mailType.put("live","smtp.live.cn"); mailType.put("msn","smtp.msn.com"); mailType.put("kum", "mail.kum.Net.cn"); mailType.put("hotmail","smtp.hotmail.cn"); return mailType; } public void setMailType(Map<String, String> mailType) { this.mailType = mailType; } } 2.設(shè)置郵件發(fā)送者的基本信息

import java.util.Date; import java.util.Properties; import javax.mail.Address; import javax.mail.BodyPart; import javax.mail.Message; import javax.mail.Multipart; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; //郵件發(fā)送器 import com.xidian.entity.MailSenderInfo; public class MailSender { /** * 根據(jù)郵件會話屬性和密碼驗證器構(gòu)造一個發(fā)送郵件的session * @return */ protected static Session getSession(MailSenderInfo mailSenderInfo){ if(mailSenderInfo == null){ return null; } MyAuthenticator authenticator = null; Properties pro = mailSenderInfo.getProperties(); if(mailSenderInfo.isValidate()){ authenticator = new MyAuthenticator(mailSenderInfo.getUsername(),mailSenderInfo.getPassword()); } return Session.getDefaultInstance(pro, authenticator); } /** * 發(fā)送文本格式郵件 * @return */ public static boolean sendTextMail(MailSenderInfo mailSenderInfo){ try { //得到session Session mailSession = getSession(mailSenderInfo); //根據(jù)session創(chuàng)建一個郵件消息 Message mailMessage=new MimeMessage(mailSession); //創(chuàng)建郵件發(fā)送者的地址 Address fromAddress=new InternetAddress(mailSenderInfo.getFromAddress()); //創(chuàng)建郵件接收者的地址 Address toAddress=new InternetAddress(mailSenderInfo.getToAddress()); //設(shè)置郵件發(fā)送者的地址 mailMessage.setFrom(fromAddress); //設(shè)置郵件接收者地址 mailMessage.setRecipient(Message.RecipientType.TO, toAddress); //設(shè)置郵件的主題 mailMessage.setSubject(mailSenderInfo.getSubject()); //設(shè)置郵件的發(fā)送內(nèi)容 mailMessage.setText(mailSenderInfo.getContent()); //設(shè)置發(fā)送郵件的時間 mailMessage.setSentDate(new Date()); //發(fā)送郵件 Transport.send(mailMessage); return true; } catch (Exception e) { e.printStackTrace(); return false; } } /** * 發(fā)送html格式郵件 * @return */ public static boolean sendHtmlMail(MailSenderInfo mailSenderInfo) { try { //得到session Session mailSession = getSession(mailSenderInfo); //根據(jù)session創(chuàng)建一個郵件消息 Message mailMessage = new MimeMessage(mailSession); //創(chuàng)建郵件發(fā)送者的地址 Address fromAddress=new InternetAddress(mailSenderInfo.getFromAddress()); //創(chuàng)建郵件接收者的地址 Address toAddress=new InternetAddress(mailSenderInfo.getToAddress()); //設(shè)置郵件發(fā)送者的地址 mailMessage.setFrom(fromAddress); //設(shè)置郵件接收者地址 mailMessage.setRecipient(Message.RecipientType.TO, toAddress); //設(shè)置郵件消息的主題 mailMessage.setSubject(mailSenderInfo.getSubject()); //設(shè)置郵件消息發(fā)送的時間 mailMessage.setSentDate(new Date()); //MiniMultipart類是一個容器類，包含MimeBodyPart類型的對象 Multipart mainPart = new MimeMultipart(); //創(chuàng)建一個包含HTML內(nèi)容的MimeBodyPart BodyPart html = new MimeBodyPart(); //設(shè)置HTML內(nèi)容 html.setContent(mailSenderInfo.getContent(), "text/html; charset=UTF-8"); //將內(nèi)容添加到容器對象中 mainPart.addBodyPart(html); //將MiniMultipart對象設(shè)置為郵件內(nèi)容 mailMessage.setContent(mainPart); //發(fā)送郵件 Transport.send(mailMessage); return true; } catch (Exception e) { e.printStackTrace(); return false; } } } 3.MyAuthenticator 繼承自Authenticator

import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; public class MyAuthenticator extends Authenticator{ String userName = null; String password = null; public MyAuthenticator(String userName, String password) { this.userName = userName; this.password = password; } @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(userName, password); } } 4.SendEmaiServlet 是郵件發(fā)送的主入口，需要注意的是其中的用戶名是用于發(fā)送郵件的郵箱賬號，密碼是經(jīng)過第三方授權(quán)的，可以通過qq郵箱，163郵箱等在身份驗證后免費獲取。
