自己在后臺拼湊一個userModel，但是數(shù)據(jù)插入失敗
上面是拼湊好的userModel，傳給userServiceImpl，執(zhí)行到下面這一步就。。。。
報錯如下：

解決了，就是下面標(biāo)黑的兩個變量調(diào)換了，弄得userDO里的變量都為null，在寫入mysql時報錯如題所示
//?實現(xiàn)userModel->user?data?object方法 private?UserDO?convertFromUserModel(UserModel?userModel)?{ ????if?(userModel?==?null)?{ ????????return?null; ????} ????UserDO?userDO?=?new?UserDO(); ????//?將userModel的屬性賦予給userDO ????BeanUtils.copyProperties(); ????return?userDO; }
