spring mvc图片上传，怎么在Controller中接收？不用上传的，只用接收？

就在红色框框里接收，或者在这个方法里接收，就好了，后面有个方法给接口就行了，求大神！在线等
大神写好的接口，我只用上传就好了
配置如下

<!-- 容器默认的DefaultServletHandler处理 所有静态内容与无RequestMapping处理的URL -->

<!-- 定义无需Controller的url<->view直接映射 -->
<mvc:view-controller path="/xzzx*" view-name="redirect:/" />

在springmvc.xml文件中配置一个CommonsMultipartResolver 的bean，然后前台上传时候命名name=“file”，在 Controller方法
public void uploadFile(@RequestParam("file") CommonsMultipartFile files){
for(CommonsMultipartFile file:files){
if(!file.isEmpty){
//在此操作上传
}else{
System.out.println("文件上传失败，请确定文件是否正确");
}
}

}

public String save(@RequestParam("file") MultipartFile path,HttpServlet request,@ModelAttribute Pic pic,Model model){
String serverPath = request.getSession().getServletContext().getRealPath(FILE_PATH);
if(!path.isEmpty()){
String picName = "filename";
File target = new File(serverPath,picName);
if(!target.exists){
target.mkdirs();
}
try{
//保存文件
path.transferTo(target);
}catcg(Exception e){
return "fail";
}

            return "success";
    }

}

配置文件中加上如下
<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="defaultEncoding">
        <value>UTF-8</value>
    </property>
    <property name="maxUploadSize">
        <value>1073741824</value>
    </property>
</bean>
后端代码这样拿，memberFile为file的name
    @RequestMapping("/batchInsertMember")
@ResponseBody
public String tobatchInsertMember(HttpServletRequest request,String memberCode)  {
    String operateName = getUserInfo(request);
    logger.info(operateName+"批量导入会员start");
    String fileName = "";
    MultipartFile file = null;
    MultipartHttpServletRequest multipartRequest = null;
    multipartRequest = (MultipartHttpServletRequest) request;

    file = multipartRequest.getFile("memberFile");
            }
