以上是两个工具类，下面是action里面的使用

     //找回密码
     public String findpwd(){
         try {
             boolean result = userService.checkEmail(item.getEmail());
             int randNum= (int) (((Math.random()+1)*1000000));
             if (result) {
                 MailSenderInfo mailInfo = new MailSenderInfo();
                 mailInfo.setMailServerHost("smtp.126.com");
                 mailInfo.setMailServerPort("25");
                 mailInfo.setValidate(true);
                 mailInfo.setUserName("chuguozhan@126.com");
                 mailInfo.setPassword("60514895a");//您的邮箱密码
                 mailInfo.setFromAddress("chuguozhan@126.com");
                 mailInfo.setToAddress(item.getEmail());
                 mailInfo.setSubject("密码找回：");
                 mailInfo.setContent("您的重置密码是："+String.valueOf(randNum));

                 SimpleMailSender sms = new SimpleMailSender();
                 if(sms.sendHtmlMail(mailInfo)){
                     User user = userService.getUserByEmail(item.getEmail());
                     user.setPassword(String.valueOf(randNum));
                     userService.doModifyPwd(user);
                     log.info("findpwd success!!!");
                     resultMap.put("retcode", RetCode.SUCCESS);
                     resultMap.put("retmsg", "重置密码已发送到了您的注册邮箱");
                 }else{
                     log.info("findpwd fail!!!");
                     resultMap.put("retcode", RetCode.FAIL);
                     resultMap.put("retmsg", "密码找回失败");
                 }
             }else{
                 log.info("checkPwd fail!!!");
                 resultMap.put("retcode", RetCode.CHECK);
                 resultMap.put("retmsg", "邮箱不存在，请确认您输入的邮箱是否正确！");
             }
         } catch (Exception e) {
             log.error("findpwd is bug",e);
             resultMap.put("retcode", RetCode.UNKOWN_WRONG);
             resultMap.put("retmsg", "密码找回出现错误！");
         }
         return SUCCESS;
     }

Dao层和Service层功能实现就不贴了
