Failed to convert property value of type java.lang.String to required type java.lang.Integer for pro

Failed to convert property value of type java.lang.String to required type java.lang.Integer for property mobile; nested exception is java.lang.NumberFormatException: For input string: "13333332233"

前一阵捣鼓一个开源项目发现这个问题是前台传值时，后台是下图这样：

public AjaxJson create(@Valid @ModelAttribute("data") User user, BindingResult result,HttpServletRequest request, HttpServletResponse response) {return doSave(user, request, response, result);}

这里的user中有个手机号DTO为Integer类型，前台转换mobile只要超过10个字符就会报上面的异常。

这个问题根本原因还是设计问题，Integer最大值为2147483647，spring遇到前端这样的超大范围会默认转成String类型，所以会报这个异常。

建议手机号这种号码类还是用字符串这种类型设计为好。
