Java注册时发送激活邮件和激活的实现示例

最近从项目分离出来的注册邮箱激活功能，整理一下，方便下次使用

1.RegisterController.java

packagecom.app.web.controller;
importjava.text.ParseException;
importjavax.annotation.Resource;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importorg.springframework.stereotype.Controller;
importorg.springframework.web.bind.annotation.RequestMapping;
importorg.springframework.web.bind.annotation.RequestMethod;
importorg.springframework.web.servlet.ModelAndView;
importcom.app.service.impl.RegisterValidateService;
importcom.app.tools.ServiceException;

@Controller
publicclassRegisterController{

@Resource
privateRegisterValidateServiceservice;

@RequestMapping(value="/user/register",method={RequestMethod.GET,RequestMethod.POST})
publicModelAndViewload(HttpServletRequestrequest,HttpServletResponseresponse)throwsParseException{
Stringaction=request.getParameter("action");
ModelAndViewmav=newModelAndView();
if("register".equals(action)){
//注册
Stringemail=request.getParameter("email");
service.processregister(email);//发邮箱激活
mav.addObject("text","注册成功");
mav.setViewName("register/register_success");
}
elseif("activate".equals(action)){
//激活
Stringemail=request.getParameter("email");//获取email
StringvalidateCode=request.getParameter("validateCode");//激活码
try{
service.processActivate(email,validateCode);//调用激活方法
mav.setViewName("register/activate_success");
}catch(ServiceExceptione){
request.setAttribute("message",e.getMessage());
mav.setViewName("register/activate_failure");
}
}
returnmav;
}

}

2.RegisterValidateService.java

packagecom.app.service.impl;
importjava.text.ParseException;
importjava.util.Date;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.stereotype.Service;
importcom.app.dao.UserDao;
importcom.app.tools.MD5Tool;
importcom.app.tools.MD5Util;
importcom.app.tools.SendEmail;
importcom.app.tools.ServiceException;
importcom.code.model.UserModel;

@Service
publicclassRegisterValidateService{

@Autowired
privateUserDaouserDao;

/**
*处理注册
*/
publicvoidprocessregister(Stringemail){
UserModeluser=newUserModel();
Longas=5480l;
user.setId(as);
user.setName("xiaoming");
user.setPassword("324545");
user.setEmail(email);
user.setRegisterTime(newDate());
user.setStatus(0);
///如果处于安全，可以将激活码处理的更复杂点，这里我稍做简单处理
//user.setValidateCode(MD5Tool.MD5Encrypt(email));
user.setValidateCode(MD5Util.encode2hex(email));

userDao.save(user);//保存注册信息

///邮件的内容
StringBuffersb=newStringBuffer("点击下面链接激活账号，48小时生效，否则重新注册账号，链接只能使用一次，请尽快激活！
");
sb.append("http://localhost:8080/springmvc/user/register?action=activate&email=");
sb.append(email);
sb.append("&validateCode=");
sb.append(user.getValidateCode());
sb.append("");

//发送邮件
SendEmail.send(email,sb.toString());
System.out.println("发送邮件");

}

/**
*处理激活
*@throwsParseException
*/
///传递激活码和email过来
publicvoidprocessActivate(Stringemail,StringvalidateCode)throwsServiceException,ParseException{
//数据访问层，通过email获取用户信息
UserModeluser=userDao.find(email);
//验证用户是否存在
if(user!=null){
//验证用户激活状态
if(user.getStatus()==0){
///没激活
DatecurrentTime=newDate();//获取当前时间
//验证链接是否过期
currentTime.before(user.getRegisterTime());
if(currentTime.before(user.getLastActivateTime())){
//验证激活码是否正确
if(validateCode.equals(user.getValidateCode())){
//激活成功，//并更新用户的激活状态，为已激活
System.out.println("==sq==="+user.getStatus());
user.setStatus(1);//把状态改为激活
System.out.println("==sh==="+user.getStatus());
userDao.update(user);
}else{
thrownewServiceException("激活码不正确");
}
}else{thrownewServiceException("激活码已过期！");
}
}else{
thrownewServiceException("邮箱已激活，请登录！");
}
}else{
thrownewServiceException("该邮箱未注册（邮箱地址不存在）！");
}

}
}

3.UserModel.java

packagecom.code.model;
importjava.beans.Transient;
importjava.util.Calendar;
importjava.util.Date;

publicclassUserModel{
privateLongid;
privateStringname;
privateStringpassword;
privateStringemail;//注册账号
privateintstatus=0;//激活状态
privateStringvalidateCode;//激活码
privateDateregisterTime;//注册时间


/////////////////
publicLonggetId(){
returnid;
}

publicvoidsetId(Longid){
this.id=id;
}

publicStringgetName(){
returnname;
}

publicvoidsetName(Stringname){
this.name=name;
}

publicStringgetPassword(){
returnpassword;
}

publicvoidsetPassword(Stringpassword){
this.password=password;
}

publicStringgetEmail(){
returnemail;
}

publicvoidsetEmail(Stringemail){
this.email=email;
}

publicintgetStatus(){
returnstatus;
}

publicvoidsetStatus(intstatus){
this.status=status;
}

publicStringgetValidateCode(){
returnvalidateCode;
}

publicvoidsetValidateCode(StringvalidateCode){
this.validateCode=validateCode;
}

publicDategetRegisterTime(){
returnregisterTime;
}

publicvoidsetRegisterTime(DateregisterTime){
this.registerTime=registerTime;
}
/////////////////////////
@Transient
publicDategetLastActivateTime(){
Calendarcl=Calendar.getInstance();
cl.setTime(registerTime);
cl.add(Calendar.DATE,2);

returncl.getTime();
}

}

4.SendEmail.java

packagecom.app.tools;
importjava.util.Date;
importjava.util.Properties;
importjavax.mail.Authenticator;
importjavax.mail.Message;
importjavax.mail.MessagingException;
importjavax.mail.PasswordAuthentication;
importjavax.mail.Session;
importjavax.mail.Transport;
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeMessage;

publicclassSendEmail{

publicstaticfinalStringHOST="smtp.163.com";
publicstaticfinalStringPROTOCOL="smtp";
publicstaticfinalintPORT=25;
publicstaticfinalStringFROM="xxxxx@xx.com";//发件人的email
publicstaticfinalStringPWD="123456";//发件人密码

/**
*获取Session
*@return
*/
privatestaticSessiongetSession(){
Propertiesprops=newProperties();
props.put("mail.smtp.host",HOST);//设置服务器地址
props.put("mail.store.protocol",PROTOCOL);//设置协议
props.put("mail.smtp.port",PORT);//设置端口
props.put("mail.smtp.auth",true);

Authenticatorauthenticator=newAuthenticator(){
@Override
protectedPasswordAuthenticationgetPasswordAuthentication(){
returnnewPasswordAuthentication(FROM,PWD);
}

};
Sessionsession=Session.getDefaultInstance(props,authenticator);

returnsession;
}

publicstaticvoidsend(StringtoEmail,Stringcontent){
Sessionsession=getSession();
try{
System.out.println("--send--"+content);
//Instantiateamessage
Messagemsg=newMimeMessage(session);

//Setmessageattributes
msg.setFrom(newInternetAddress(FROM));
InternetAddress[]address={newInternetAddress(toEmail)};
msg.setRecipients(Message.RecipientType.TO,address);
msg.setSubject("账号激活邮件");
msg.setSentDate(newDate());
msg.setContent(content,"text/html;charset=utf-8");

//Sendthemessage
Transport.send(msg);
}
catch(MessagingExceptionmex){
mex.printStackTrace();
}
}
}
