@RequestMapping(value="/editItems", method={RequestMethod.POST,RequestMethod.GET}) //限制Http请求方式

//@RequestParam 将请求参数 与 形式参数进行绑定 required:指定属性必须传入值 defaultValue:设置默认值

public String editItems(Model model, @RequestParam(value="id",required=true,defaultValue="0") Integer itemsId) throws Exception{

ItemsCustom itemsCustom=itemsService.findItemsById(itemsId);

if(itemsCustom==null){

throw new CustomException("商品不存在");

}

model.addAttribute("itemsCustom", itemsCustom);

return "editItems";

}

@RequestMapping(value="/updateItems")

public String editItemsSubmit(Integer id,ItemsCustom itemsCustom,MultipartFile itemsPic) throws Exception{

String uploadFileName=itemsPic.getOriginalFilename();//获取上传的文件名

if(itemsPic!=null && uploadFileName!=null && !uploadFileName.equals("")){

String imagesPath="E:\\develop\\upload\\images\\";

String newFileName=UUID.randomUUID()+uploadFileName.substring(uploadFileName.lastIndexOf("."),uploadFileName.length());

File newFile=new File(imagesPath+newFileName);

itemsPic.transferTo(newFile);//将内存中的数据写入磁盘

itemsCustom.setPic(newFileName);

}

itemsService.updateItemsById(id, itemsCustom);

return "redirect:findItemsList.do"; //重定向

}

//JSON的使用 @ResponseBody：将对像转json输出 @RequestBody:将请求参数转 java对象

@RequestMapping(value="/jsonRequest")

public @ResponseBody ItemsCustom jsonRequest(@RequestBody ItemsCustom itemsCustom) throws Exception{

return itemsCustom;

}

//RestFul 风格 编程 /restFulRequest/{id}：表示将这个位置的参数传到 @PathVariable 指定的名称中

@RequestMapping(value="/restFulRequest/{id}")

public @ResponseBody ItemsCustom restFulRequest(@PathVariable("id") Integer id) throws Exception{

ItemsCustom itemsCustom=itemsService.findItemsById(id);

return itemsCustom;

}

}
