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。

importjava.util.hashmap;importjava.util.map;importjava.util.properties;publicclassmailsenderinfo{privatestringmailserverhost;//发送邮件的服务器privatestringmailserverport="587";//发送邮件的服务器的端口privatestringfromaddress;//发送者地址privatestringtoaddress;//接收者地址privatestringusername;//发送者用户名privatestringpassword;//发送者密码privatebooleanvalidate=true;//是否需要身份验证privatestringsubject;//邮件主题privatestringcontent;//邮件内容privatemapmailtype;//邮箱类型//得到邮件会话属性publicpropertiesgetproperties(){propertiesp=newproperties();p.put("mail.smtp.host",this.mailserverhost);p.put("mail.smtp.port",this.mailserverport);p.put("mail.smtp.auth",validate?"true":"false");returnp;}publicstringgetmailserverhost(){returnmailserverhost;}publicvoidsetmailserverhost(stringmailserverhost){this.mailserverhost=mailserverhost;}publicstringgetmailserverport(){returnmailserverport;}publicvoidsetmailserverport(stringmailserverport){this.mailserverport=mailserverport;}publicstringgetfromaddress(){returnfromaddress;}publicvoidsetfromaddress(stringfromaddress){this.fromaddress=fromaddress;}publicstringgettoaddress(){returntoaddress;}publicvoidsettoaddress(stringtoaddress){this.toaddress=toaddress;}publicstringgetusername(){returnusername;}publicvoidsetusername(stringusername){this.username=username;this.fromaddress=username;if(username!=null&&username.length()>0){stringfromemailext=username.substring(username.lastindexof("@")+1,username.lastindexof("."));this.mailserverhost=getmailtype().get(fromemailext);}}publicstringgetpassword(){returnpassword;}publicvoidsetpassword(stringpassword){this.password=password;}publicbooleanisvalidate(){returnvalidate;}publicvoidsetvalidate(booleanvalidate){this.validate=validate;}publicstringgetsubject(){returnsubject;}publicvoidsetsubject(stringsubject){this.subject=subject;}publicstringgetcontent(){returncontent;}publicvoidsetcontent(stringcontent){this.content=content;}publicmapgetmailtype(){mailtype=newhashmap();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");returnmailtype;}publicvoidsetmailtype(mapmailtype){this.mailtype=mailtype;}}2.设置邮件发送者的基本信息

importjava.util.date;importjava.util.properties;importjavax.mail.address;importjavax.mail.bodypart;importjavax.mail.message;importjavax.mail.multipart;importjavax.mail.session;importjavax.mail.transport;importjavax.mail.internet.internetaddress;importjavax.mail.internet.mimebodypart;importjavax.mail.internet.mimemessage;importjavax.mail.internet.mimemultipart;//邮件发送器importcom.xidian.entity.mailsenderinfo;publicclassmailsender{/***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*/protectedstaticsessiongetsession(mailsenderinfomailsenderinfo){if(mailsenderinfo==null){returnnull;}myauthenticatorauthenticator=null;propertiespro=mailsenderinfo.getproperties();if(mailsenderinfo.isvalidate()){authenticator=newmyauthenticator(mailsenderinfo.getusername(),mailsenderinfo.getpassword());}returnsession.getdefaultinstance(pro,authenticator);}/***发送文本格式邮件*@return*/publicstaticbooleansendtextmail(mailsenderinfomailsenderinfo){try{//得到sessionsessionmailsession=getsession(mailsenderinfo);//根据session创建一个邮件消息messagemailmessage=newmimemessage(mailsession);//创建邮件发送者的地址addressfromaddress=newinternetaddress(mailsenderinfo.getfromaddress());//创建邮件接收者的地址addresstoaddress=newinternetaddress(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(newdate());//发送邮件transport.send(mailmessage);returntrue;}catch(exceptione){e.printstacktrace();returnfalse;}}/***发送html格式邮件*@return*/publicstaticbooleansendhtmlmail(mailsenderinfomailsenderinfo){try{//得到sessionsessionmailsession=getsession(mailsenderinfo);//根据session创建一个邮件消息messagemailmessage=newmimemessage(mailsession);//创建邮件发送者的地址addressfromaddress=newinternetaddress(mailsenderinfo.getfromaddress());//创建邮件接收者的地址addresstoaddress=newinternetaddress(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(newdate());//minimultipart类是一个容器类，包含mimebodypart类型的对象multipartmainpart=newmimemultipart();//创建一个包含html内容的mimebodypartbodyparthtml=newmimebodypart();//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);returntrue;}catch(exceptione){e.printstacktrace();returnfalse;}}}3.myauthenticator继承自authenticator

importjavax.mail.authenticator;importjavax.mail.passwordauthentication;publicclassmyauthenticatorextendsauthenticator{stringusername=null;stringpassword=null;publicmyauthenticator(stringusername,stringpassword){this.username=username;this.password=password;}@overrideprotectedpasswordauthenticationgetpasswordauthentication(){returnnewpasswordauthentication(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。
