進行用戶注冊，能夠成功的注冊，但是Nick列顯示的總是false。以下是我的代碼：

//service代碼
@Override
@Transactional//事務提交，防止出錯
public?void?register(UserModel?userModel)?throws?BusinessException?{
????if(userModel==null){
????????throw?new?BusinessException(EmBussinessError.PARAMETER_VALIDATION_ERROR,"對象為空");
????}
???if(StringUtils.isEmpty(userModel.getNick())||userModel.getGender()==null||
???userModel.getAge()==null||StringUtils.isEmpty(userModel.getTelphone())){
???????throw?new?BusinessException(EmBussinessError.PARAMETER_VALIDATION_ERROR,"入參不合法");
???}
???UserDO?userDO=convertFromUserModel(userModel);//實現model到dataobject方法；
???userDOMapper.insertSelective(userDO);
???userModel.setId(userDO.getId());
???UserPasswordDO?userPasswordDO=convertPasswprdFromModel(userModel);//實現model到dataobject
????userPasswordDOMapper.insertSelective(userPasswordDO);

???return;
}
//將model轉化為userDo
public?UserDO?convertFromUserModel(UserModel?userModel){
????if(userModel==null){
????????return?null;
????}
????UserDO?userDO=new?UserDO();
????BeanUtils.copyProperties(userModel,userDO);
????return?userDO;
}
//獲取password信息
private?UserPasswordDO?convertPasswprdFromModel(UserModel?userModel){
????if(userModel==null){
????????return?null;
????}
????UserPasswordDO??userPasswordDO=new?UserPasswordDO();
????userPasswordDO.setEncrptpassword(userModel.getEncrptpassword());
????userPasswordDO.setUserId(userModel.getId());
????return?userPasswordDO;
}

//controller代碼?
//用戶注冊接口
@RequestMapping(value?=?"/register",method?=?{RequestMethod.POST},consumes?=?{CONTENT_TYPE_FORMED})//獲得個頭圖片的映射
@ResponseBody
public?CommonReturnType?register(@RequestParam(name="telphone")String?telphone,
?????????????????????????????????@RequestParam(name="otpCode")String?otpCode,
?????????????????????????????????@RequestParam(name="nick")String?nick,
?????????????????????????????????@RequestParam(name="gender")String?gender,
?????????????????????????????????@RequestParam(name="age")Integer?age,
?????????????????????????????????@RequestParam(name="password")String?password)?throws?BusinessException,?UnsupportedEncodingException,?NoSuchAlgorithmException?{
????//驗證手機號和對應的otpcode相符合
????String?insessionOtpCode=?(String)?this.httpServletRequest.getSession().getAttribute(telphone);
????if(!StringUtils.equals(otpCode,insessionOtpCode)){
????????throw?new?BusinessException(EmBussinessError.PARAMETER_VALIDATION_ERROR,"短信驗證碼不正確");
????}

????//用戶的注冊流程
????UserModel?userModel=new?UserModel();
????userModel.setNick(nick);
????userModel.setGender(gender);
????userModel.setAge(age);
????userModel.setTelphone(telphone);
????userModel.setEncrptpassword(this.EncodeByMd5(password));

????userService.register(userModel);
????return?CommonReturnType.create(null);
}

描述清楚一點
