点击邮箱里的找回密码

@Action("validate")public String callbackToken() {account = accountServices.validateMailAndToken(email,token);    if(account == null) {        return INPUT;    }    return SUCCESS;}

 

//service中 public Account validateMailAndToken(String email, String token) {        String cacheToken = (String) Cache.get("forget:"+email);        if(cacheToken == null) {            System.out.println("获取不了token");            return null;        } else {            if(token.equals(cacheToken)) {                Cache.remove("forget:"+email);                return accountDao.findByemail(email);            } else {                System.out.println("两个token不一致");                return null;            }        }    }
