SSM框架 图片上传

图片是通过 （反正是file形式的）

 <input type="file" name="houseImg5" id="inter5"/>

传到controller的参数 使用MultipartFile 形式 好像上传七牛云比较方便 （网上这么说的

 @RequestMapping("toHousePost2")
    public String toHousePost2(@Param(value = "houseTitle")String houseTitle,
                               @Param(value = "houseAddress")String houseAddress,
