邮箱验证码功能实现

在进行实际项目的开发过程中，我们可能会遇到需要需要对用户账号密码进行找回，这时就需要我们通过邮件进行验证，从而对用户信息进行修改，下面我就将自己开发过程中的邮件发送功能简单描述一下，供大家学习使用。
1.mailsenderinfo是确定邮件发送的类型及其各种属性
import java.util.hashmap; import java.util.map; import java.util.properties; public class mailsenderinfo { private string mailserverhost; //发送邮件的服务器 private string mailserverport=”587″; //发送邮件的服务器的端口 private string fromaddress; //发送者地址 private string toaddress; //接收者地址 private string username; //发送者用户名 private string password; //发送者密码 private boolean validate=true; //是否需要身份验证 private string subject; //邮件主题 private string content; //邮件内容 private map<string, string> mailtype; //邮箱类型 //得到邮件会话属性 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 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.设置邮件发送者的基本信息
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; //邮件发送器 import com.xidian.entity.mailsenderinfo; public class mailsender { / * 根据邮件会话属性和密码验证器构造一个发送邮件的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); } / * 发送文本格式邮件 * @return */ public static boolean sendtextmail(mailsenderinfo mailsenderinfo){ try { //得到session session mailsession = getsession(mailsenderinfo); //根据session创建一个邮件消息 message mailmessage=new mimemessage(mailsession); //创建邮件发送者的地址 address fromaddress=new internetaddress(mailsenderinfo.getfromaddress()); //创建邮件接收者的地址 address toaddress=new internetaddress(mailsenderinfo.gettoaddress()); //设置邮件发送者的地址 mailmessage.setfrom(fromaddress); //设置邮件接收者地址 mailmessage.setrecipient(message.recipienttype.to, toaddress); //设置邮件的主题 mailmessage.setsubject(mailsenderinfo.getsubject()); //设置邮件的发送内容 mailmessage.settext(mailsenderinfo.getcontent()); //设置发送邮件的时间 mailmessage.setsentdate(new date()); //发送邮件 transport.send(mailmessage); return true; } catch (exception e) { e.printstacktrace(); return false; } } / * 发送html格式邮件 * @return */ public static boolean sendhtmlmail(mailsenderinfo mailsenderinfo) { try { //得到session session mailsession = getsession(mailsenderinfo); //根据session创建一个邮件消息 message mailmessage = new mimemessage(mailsession); //创建邮件发送者的地址 address fromaddress=new internetaddress(mailsenderinfo.getfromaddress()); //创建邮件接收者的地址 address toaddress=new internetaddress(mailsenderinfo.gettoaddress()); //设置邮件发送者的地址 mailmessage.setfrom(fromaddress); //设置邮件接收者地址 mailmessage.setrecipient(message.recipienttype.to, toaddress); //设置邮件消息的主题 mailmessage.setsubject(mailsenderinfo.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(mailsenderinfo.getcontent(), “text/html; charset=utf-8”); //将内容添加到容器对象中 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 (exception e) { e.printstacktrace(); return false; } } } 3.myauthenticator 继承自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 是邮件发送的主入口，需要注意的是其中的用户名是用于发送邮件的邮箱账号，密码是经过第三方授权的，可以通过qq邮箱，163邮箱等在身份验证后免费获取。
import java.io.ioexception; import java.io.printwriter; import java.util.random; import javax.servlet.servletexception; import javax.servlet.http.httpservlet; import javax.servlet.http.httpservletrequest; import javax.servlet.http.httpservletresponse; import com.xidian.entity.account; import com.xidian.entity.mailsenderinfo; import com.xidian.service.accountservice; import com.xidian.service.impl.accountserviceimpl; import com.xidian.service.impl.mailsender; public class sendemailservlet extends httpservlet{ @override public void doget(httpservletrequest req, httpservletresponse resp) throws servletexception, ioexception { // todo auto-generated method stub dopost(req, resp); } @override public void dopost(httpservletrequest req, httpservletresponse resp) throws servletexception, ioexception { // todo auto-generated method stub resp.setcontenttype(“text/html;charset=utf-8”); resp.setcharacterencoding(“utf-8”); req.setcharacterencoding(“utf-8”); mailsenderinfo senderinfo=new mailsenderinfo(); string email = req.getparameter(“email”); accountservice as = new accountserviceimpl(); account account = as.querybyemail(email); if(account ==null){ printwriter out = resp.getwriter(); out.println(“<script type=\\\’text/javascript\\\’>” “alert(\\\’您输入的邮箱不存在！\\\’);” “location.href=\\\’noregister.jsp\\\’;” “</script>”); }else{ senderinfo.setusername(“123456789@qq.com”); //用户名 senderinfo.setpassword(“xxxxxxxxxxxxxxxxx”); //密码 senderinfo.settoaddress(email);//接收者 senderinfo.setsubject(“battle邮箱验证”); //主题 random random = new random(); // int result=random.nextint(10); string num = (int)(math.random()*1000000) “”; string str =”您的暴雪游戏验证码为：” num “，请保护好您的验证码安全不要告诉他人！”; senderinfo.setcontent(str); //内容 //发送 mailsender.sendhtmlmail(senderinfo); req.setattribute(“num”, num); req.setattribute(“email”, email); req.getrequestdispatcher(“email.jsp”).forward(req, resp); } } }
