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
package com.app.web.controller;
import java.text.ParseException;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.app.service.impl.RegisterValidateService;
import com.app.tools.ServiceException;
@Controller
public class RegisterController {
@Resource
private RegisterValidateService service;
@RequestMapping(value="/user/register",method={RequestMethod.GET,RequestMethod.POST})
public ModelAndView load(HttpServletRequest request,HttpServletResponse response) throws ParseException{
String action = request.getParameter("action");
ModelAndView mav=new ModelAndView();
if("register".equals(action)) {
//注册
String email = request.getParameter("email");
service.processregister(email);//发邮箱激活
mav.addObject("text","注册成功");
mav.setViewName("register/register_success");
}
else if("activate".equals(action)) {
//激活
String email = request.getParameter("email");//获取email
String validateCode = request.getParameter("validateCode");//激活码
try {
service.processActivate(email , validateCode);//调用激活方法
mav.setViewName("register/activate_success");
} catch (ServiceException e) {
request.setAttribute("message" , e.getMessage());
mav.setViewName("register/activate_failure");
}
}
return mav;
}
}
2.RegisterValidateService.java
package com.app.service.impl;
import java.text.ParseException;
import java.util.Date;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.app.dao.UserDao;

import com.app.tools.MD5Util;
import com.app.tools.SendEmail;
import com.app.tools.ServiceException;
import com.code.model.UserModel;
@Service
public class RegisterValidateService {
@Autowired
private UserDao userDao;
/**
* 处理注册
*/
public void processregister(String email){
UserModel user=new UserModel();
Long as=5480l;
user.setId(as);
user.setName("xiaoming");
user.setPassword("324545");
user.setEmail(email);
user.setRegisterTime(new Date());
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
StringBuffer sb=new StringBuffer("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！</br>");
sb.append("<a href=\"http://localhost:8080/springmvc/user/register?action=activate&email=");
sb.append(email);
sb.append("&validateCode=");
sb.append(user.getValidateCode());
sb.append("\">http://localhost:8080/springmvc/user/register?action=activate&email=");
sb.append(email);
sb.append("&validateCode=");
sb.append(user.getValidateCode());
sb.append("</a>");
//发送邮件
SendEmail.send(email, sb.toString());
System.out.println("发送邮件");
}
/**
* 处理激活
* @throws ParseException
*/
///传递激活码和email过来
public void processActivate(String email , String validateCode)throws ServiceException, ParseException{
//数据访问层，通过email获取用户信息
UserModel user=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
Date currentTime = new Date();//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 {
throw new ServiceException("激活码不正确");
}
} else { throw new ServiceException("激活码已过期！");
}
} else {
throw new ServiceException("邮箱已激活，请登录！");
}
} else {
throw new ServiceException("该邮箱未注册（邮箱地址不存在）！");
}
}
}

/**

*/
private static Session getSession() {
