控制器：

public JsonResultObject add(MultipartHttpServletRequest request){
        try{
            String name = RequestHelper.getRequest(request,"name");
            String value = RequestHelper.getRequest(request,"value");
            boolean isUse = Boolean.parseBoolean(RequestHelper.getRequest(request,"isUse"));
            String picUrl = saveFile(request.getFile("file"));//上传文件参数名为：file

            Banks banks = new Banks();
            banks.setName(name);
            banks.setValue(value);
            banks.setPicUrl(picUrl);
            banks.setUse(isUse);

            banksService.save(banks);

            return JsonResultObject.getOk();
        }catch (Exception e){
            return JsonResultObject.getFail(e.getMessage());

单元测试：

@Autowired
    BanksController banksController;

    @Test
    public void testAdd() throws IOException {
        RegisterConfig.RootPath = "E:\\work\\Admin";
        FileInputStream fis = new FileInputStream("E:\\Images\\1.gif");
        MockMultipartFile file = new MockMultipartFile("file","1.gif","image/jpeg",fis);

        MockMultipartHttpServletRequest request = new MockMultipartHttpServletRequest() ;
        request.addFile(file);

        request.setParameter("name","test");
        request.setParameter("value","tttt");
        request.setParameter("isUse","true");

        JsonResultObject jsonResultObject = banksController.add(request);
        System.out.println(jsonResultObject.getData());
    }

使用的request 是 ：MultipartHttpServletRequest
