我使用下方法
@RequestMapping("/addHouse.do")
public String addHouse(
@RequestParam(value ="companyId", required = true) int companyId ,
@RequestParam(value ="pics", required = false) CommonsMultipartFile pics ,
HttpServletRequest request,HttpServletResponse response, ModelMap model){
...
...
model.addAttribute("pics", pics);
return "redirect:/addHousePic.do";
样结传addHousePic.do处理之 pics空 companyId能成功传
请问回事 解决

required=false
