如標(biāo)題，這種可以返回

但如果是get請(qǐng)求，傳字符串參數(shù)，

返回值：

{

? ? "code": -1,

? ? "msg": "An Errors/BindingResult argument is expected to be declared immediately after the model attribute, the @RequestBody or the @RequestPart arguments to which they apply: public com.example.demo.model.CommonMsg com.example.demo.controller.UservisitorController.SelectAll(org.springframework.validation.BindingResult)",

? ? "data": null

}
