大致说下核心的东西，其实就是JAVAMAIL,下面是邮件发送的核心依赖：
javax.mail
mail
1.4.7
javax.activation
activation
1.1-rev-1
dom4j
dom4j
具体的邮件发送类，首先是邮件信息类：
package com.blog.common.drframework.mail; import java.util.Properties; /** * 功能：邮件信息实体 * Author: DR.YangLong * Date: 14-3-4 * Time: 下午12:16 * Email:[email protected] */ public class MailSender { // 发送邮件的服务器的IP和端口 private String mailServerHost; private String mailServerPort = "25"; // 邮件发送者的地址 private String fromAddress; // 邮件接收者的地址 private String toAddress; // 登陆邮件发送服务器的用户名和密码 private String userName; private String password; // 是否需要身份验证 private boolean validate = false; // 邮件主题 private String subject; // 邮件的文本内容 private String content; // 邮件附件的文件名 private String[] attachFileNames; /** * 获得邮件会话属性 */ 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 boolean isValidate() { return validate; } public void setValidate(boolean validate) { this.validate = validate; } public String[] getAttachFileNames() { return attachFileNames; } public void setAttachFileNames(String[] fileNames) { this.attachFileNames = fileNames; } public String getFromAddress() { return fromAddress; } public void setFromAddress(String fromAddress) { this.fromAddress = fromAddress; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } 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; } public String getSubject() { return subject; } public void setSubject(String subject) { this.subject = subject; } public String getContent() { return content; } public void setContent(String textContent) { this.content = textContent; } }
然后是验证器：
package com.blog.common.drframework.mail; import javax.mail.PasswordAuthentication; import javax.mail.Authenticator; /** * 功能：验证器 * Author: DR.YangLong * Date: 14-3-4 * Time: 下午12:47 * Email:[email protected] */ public class MailAuthenticator extends Authenticator{ String userName=null; String password=null; public MailAuthenticator(){ } public MailAuthenticator(String username, String password) { this.userName = username; this.password = password; } protected PasswordAuthentication getPasswordAuthentication(){ return new PasswordAuthentication(userName, password); } }
接着，邮件发送功能实现类：
package com.blog.common.drframework.mail; import javax.mail.*; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; import java.util.Date; import java.util.Properties; /** * 功能：邮件发送service provider * Author: DR.YangLong * Date: 14-3-4 * Time: 下午12:17 * Email:[email protected] */ public class SimpleMailSender { /** * 以文本格式发送邮件 * @param mailInfo 待发送的邮件的信息 */ public boolean sendTextMail(MailSender mailInfo) { // 判断是否需要身份认证 MailAuthenticator authenticator = null; Properties pro = mailInfo.getProperties(); if (mailInfo.isValidate()) { // 如果需要身份认证，则创建一个密码验证器 authenticator = new MailAuthenticator(mailInfo.getUserName(), mailInfo.getPassword()); } // 根据邮件会话属性和密码验证器构造一个发送邮件的session Session sendMailSession = Session.getDefaultInstance(pro,authenticator); try { // 根据session创建一个邮件消息 Message mailMessage = new MimeMessage(sendMailSession); // 创建邮件发送者地址 Address from = new InternetAddress(mailInfo.getFromAddress()); // 设置邮件消息的发送者 mailMessage.setFrom(from); // 创建邮件的接收者地址，并设置到邮件消息中 Address to = new InternetAddress(mailInfo.getToAddress()); mailMessage.setRecipient(Message.RecipientType.TO,to); // 设置邮件消息的主题 mailMessage.setSubject(mailInfo.getSubject()); // 设置邮件消息发送的时间 mailMessage.setSentDate(new Date()); // 设置邮件消息的主要内容 String mailContent = mailInfo.getContent(); mailMessage.setText(mailContent); // 发送邮件 Transport.send(mailMessage); return true; } catch (MessagingException ex) { ex.printStackTrace(); } return false; } /** * 以HTML格式发送邮件 * @param mailInfo 待发送的邮件信息 */ public static boolean sendHtmlMail(MailSender mailInfo){ // 判断是否需要身份认证 MailAuthenticator authenticator = null; Properties pro = mailInfo.getProperties(); //如果需要身份认证，则创建一个密码验证器 if (mailInfo.isValidate()) { authenticator = new MailAuthenticator(mailInfo.getUserName(), mailInfo.getPassword()); } // 根据邮件会话属性和密码验证器构造一个发送邮件的session Session sendMailSession = Session.getDefaultInstance(pro,authenticator); try { // 根据session创建一个邮件消息 Message mailMessage = new MimeMessage(sendMailSession); // 创建邮件发送者地址 Address from = new InternetAddress(mailInfo.getFromAddress()); // 设置邮件消息的发送者 mailMessage.setFrom(from); // 创建邮件的接收者地址，并设置到邮件消息中 Address to = new InternetAddress(mailInfo.getToAddress()); // Message.RecipientType.TO属性表示接收者的类型为TO mailMessage.setRecipient(Message.RecipientType.TO,to); // 设置邮件消息的主题 mailMessage.setSubject(mailInfo.getSubject()); // 设置邮件消息发送的时间 mailMessage.setSentDate(new Date()); // MiniMultipart类是一个容器类，包含MimeBodyPart类型的对象 Multipart mainPart = new MimeMultipart(); // 创建一个包含HTML内容的MimeBodyPart BodyPart html = new MimeBodyPart(); // 设置HTML内容 html.setContent(mailInfo.getContent(), "text/html; charset=utf-8"); mainPart.addBodyPart(html); // 将MiniMultipart对象设置为邮件内容 mailMessage.setContent(mainPart); // 发送邮件 Transport.send(mailMessage); return true; } catch (MessagingException ex) { ex.printStackTrace(); } return false; } }
最后是一个测试类，不基于测试框架：
package com.blog.common.drframework.mail; /** * 功能：测试邮件发送 * Author: DR.YangLong * Date: 14-3-4 * Time: 下午2:09 * Email:[email protected] */ public class MailTest { public static void main(String[] args){ //这个类主要是设置邮件 MailSender mailInfo = new MailSender(); mailInfo.setMailServerHost("smtp.163.com"); mailInfo.setMailServerPort("25"); mailInfo.setValidate(true); mailInfo.setUserName("[email protected]"); mailInfo.setPassword("XXXXXXX密码");//邮箱密码 mailInfo.setFromAddress("[email protected]"); mailInfo.setToAddress("[email protected]"); mailInfo.setSubject("设置邮箱标题 密码找回"); mailInfo.setContent("设置邮箱内容 如点击http://dr-yanglong.iteye.com/找回密码"); //这个类主要来发送邮件 SimpleMailSender sms = new SimpleMailSender(); sms.sendTextMail(mailInfo);//发送文体格式 sms.sendHtmlMail(mailInfo);//发送html格式 } }
当然这是最简单，为了安全，密码不能以明文出现，因此必须使用密文，要自定义加解密类或方法，之后需要去重写javamail读取密码的方法，加入你自己的解密方法。
以上是不依托业务的邮件发送，使用发送邮件验证激活或密码修改，这个是一个核心，另外一个核心就是验证参数的设置，下面是最简单的方式，仅供参考：
业务层：
package com.blog.coreImp; import com.blog.common.drframework.mail.MailSender; import com.blog.common.drframework.mail.SimpleMailSender; import com.blog.core.ResetPasswordService; import com.blog.daoImp.ResetPasswordDAOImp; import com.blog.daoImp.UserInfoDAOImp; import com.blog.daoImp.UserLoginDAOImp; import com.blog.model.ResetPassword; import com.blog.model.UserLogin; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import java.util.Date; import java.util.UUID; /** * 功能：密码重设服务接口实现。 * Author: DR.YangLong * Date: 14-3-6 * Time: 上午9:09 * Email:[email protected] */ @Service @Transactional public class ResetPasswordServiceImp implements ResetPasswordService { @Autowired private ResetPasswordDAOImp resetPasswordDAOImp; /** * 发送修改密码邮件 * @param account 帐号 */ @Override public void addValidateSendEmail(String account) { //生成修改密码对象 String id=UUID.randomUUID().toString(); ResetPassword resetPassword=new ResetPassword(); resetPassword.setId(id); resetPassword.setOptime(new Date()); //保存到数据库 resetPasswordDAOImp.save(resetPassword); //设置邮件对象 MailSender mailSender=new MailSender(); mailSender.setMailServerHost("smtp.163.com"); mailSender.setMailServerPort("25"); //设置验证器 mailSender.setValidate(true); //发送邮箱地址 mailSender.setFromAddress("[email protected]"); //接收邮箱地址 mailSender.setToAddress("[email protected]"); //设置邮件用户名 mailSender.setUserName("[email protected]"); //设置密码 mailSender.setPassword("XXXXX"); //设置邮件主题 mailSender.setSubject("密码找回"); //生成链接 String uri="http://127.0.0.1:8080/getpassword/resetpwd.html"+"?uuid="+id+"&account="+account; mailSender.setContent("您申请了密码找回，请点击链接修改："+uri); //发送邮件 SimpleMailSender sms = new SimpleMailSender(); sms.sendHtmlMail(mailSender); } /** * * @param uuid * @param account * @param newPassword */ @Override public String resetPassword(String uuid, String account, String newPassword) { String msg="success"; ResetPassword resetPassword=resetPasswordDAOImp.findById(uuid); if(resetPassword!=null){ // String sql="update user_login set pwd='"+newPassword+"' where account = '"+account+"'"; // resetPasswordDAOImp.excudeSQL(sql); String sql="update user_login set pwd=? where account=?"; resetPasswordDAOImp.batchUpdateOrDelete(sql,newPassword,account); return msg; } msg="timeout"; return msg; } }
Controller层：
package com.blog.controllerImp; import com.blog.controller.ResetPasswordController; import com.blog.coreImp.ResetPasswordServiceImp; import com.blog.coreImp.UserLoginServiceImp; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Scope; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import javax.servlet.http.HttpSession; /** * 功能：重设密码 * Author: DR.YangLong * Date: 14-3-4 * Time: 上午10:22 * Email:[email protected] */ @Controller @RequestMapping(value = "/getpassword") @Scope(value = "prototype") public class ResetPasswordControllerImp implements ResetPasswordController { @Autowired private ResetPasswordServiceImp resetService; @Autowired private UserLoginServiceImp loginService; /** * 使用simple mail生成连接并发送到邮箱 * @param account 帐号 * @return String json */ @RequestMapping(value ="/presentreset.html") @ResponseBody @Override public String generateResetURI(@RequestParam(value = "account",required = false)String account){ String msg = "{\"msg\":\"无此用户！\",\"success\":\"false\",\"url\":\"\"}"; //验证是否有此用户 if(loginService.checkAccount(account)!=0){ resetService.addValidateSendEmail(account); msg= "{\"msg\":\"\",\"success\":\"true\",\"url\":\"/sendemailsuccess.jsp\"}"; return msg; } return msg; } /** * 跳转到重设密码页面，同时将用户修改依据凭证放入session中，或返回视图再传递回来 * @param account 帐号 * @param uuid 修改验证id * @param session 当前会话 * @return 重设密码页面 */ @RequestMapping(value = "/resetpwd.html") @Override public String toReset(@RequestParam(value = "account",required = false)String account,@RequestParam(value = "uuid",required = false)String uuid,HttpSession session) { session.setAttribute("account",account); session.setAttribute("uuid",uuid); return "resetpassword"; } /** * 重设密码 * @param pwd 新密码 * @param session 当前会话 * @return 重设结果页 */ @RequestMapping(value ="/reset.html") @Override public String resetPassword(@RequestParam(value = "password", required = false)String pwd,HttpSession session) { String account=(String)session.getAttribute("account"); String uuid=session.getAttribute("uuid").toString(); if(account!=null&&uuid!=null){ String result=resetService.resetPassword(uuid,account,pwd); if(result.equals("success")){ session.removeAttribute("account"); session.removeAttribute("uuid"); return "resetsuccess"; } return "timeout"; } return "notexist"; } }
到此，最简单的验证修改就完成了，激活和此类似，上面仅提供核心的东西。也是一个空闲时做着练手的，不妥之处请包涵，并留言指出，十分感谢！
