SpringBoot构建电商基础秒杀项目 学习笔记
UserService 添加
void register(UserModel userModel) throws BusinessException;
UserServiceImpl 添加
@Override
@Transactional // 事务操作
public void register(UserModel userModel) throws BusinessException {
if(userModel == null){
throw new BusinessException(EmBusinessError.PARAMETER_VALIDATION_ERROR);
}
if(StringUtils.isEmpty(userModel.getTelphone())
|| StringUtils.isEmpty(userModel.getName())
|| userModel.getGender() == null
|| userModel.getAge() == null
|| StringUtils.isEmpty(userModel.getEncrptPassword())){
throw new BusinessException(EmBusinessError.PARAMETER_VALIDATION_ERROR);
}
UserDO userDO = convertFromModel(userModel);
try{
userDOMapper.insertSelective(userDO);
}catch (DuplicateKeyException ex){
throw new BusinessException(EmBusinessError.PARAMETER_VALIDATION_ERROR, "手机号码已注册");
}
userModel.setId(userDO.getId()); // 获取自增 id
UserPasswordDO userPasswordDO = convertPasswordFromModel(userModel);
userPasswordDOMapper.insertSelective(userPasswordDO);
return;
}
private UserDO convertFromModel(UserModel userModel){

}

}
UserPasswordDO userPasswordDO = new UserPasswordDO();
userPasswordDO.setEncrptPassword(userModel.getEncrptPassword());
userPasswordDO.setUserId(userModel.getId());
return userPasswordDO;
}
userDOMapper.xml 修改
返回自增 id
<insert id="insertSelective" parameterType="com.karonda.dataobject.UserDO" keyProperty="id" useGeneratedKeys="true">
UserController 修改
@CrossOrigin(allowCredentials = "true", allowedHeaders = "*") // 解决跨域问题
@RequestMapping(value = "/register", method = {RequestMethod.POST}, consumes = {CONTENT_TYPE_FORMED})

withCredentials 要设置为 true (getotp.html 同样需要设置)
