# **单个文件** #

@ApiOperation(value = "上传视频接口",notes = "上传视频接口")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "uId",value = "上传用户ID，",paramType = "query",required = true,dataType = "int")
    })
    @PostMapping(value = "/video/uplode", headers = "content-type=multipart/form-data")
    public ResponseJsonCode uplode(HttpServletRequest request,@RequestParam(value = "uId", required = true) String uId, @RequestParam(value = "file", required = true) MultipartFile file) {
        Map<String,Object> dataMap = new HashMap<String,Object>();
        String path="";
        log.info("file:"+file.length+"; uId:"+uId+"; path:"+path);
        List<Map<String,Object>> list =  IOUtil.appMvcUpload(path, file, request,dataMap);
        return null==list.get(0).get("error")?ResponseJsonCode.successRequestJsonCode(list):ResponseJsonCode.errorRequestJsonCode(list);
    }

至于多文件的我想swagger应该不支持吧，反正我是没研究出来。。

# **多文件（用postman测试）** #

@ApiOperation(value = "文件上传",notes = "文件上传")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "files",value = "多个文件，",paramType = "formData",allowMultiple=true,required = true,dataType = "file"),
            @ApiImplicitParam(name = "uId",value = "上传用户ID，",paramType = "query",required = true,dataType = "int")
    })
    @PostMapping(value = "/uplode", headers = "content-type=multipart/form-data")
    public ResponseJsonCode uplode(HttpServletRequest request,@RequestParam(value = "uId", required = true) String uId, @RequestParam(value = "files", required = true) MultipartFile[] files) {
        Map<String,Object> dataMap = new HashMap<String,Object>();
        String path="";
        log.info("files:"+files.length+";uId:"+uId+":   path:"+path);
    
        List<Map<String,Object>> list =  IOUtil.appMvcUpload(path, files, request,dataMap);
        return null==list.get(0).get("error")?ResponseJsonCode.successRequestJsonCode(list):ResponseJsonCode.errorRequestJsonCode(list);
    }

如果postman测试文件上传，后台接受文件为null，则是你postman这边设置有问题

一是看请求方式

二是headers里面是空

三是接受key是否正确

四是文件类型是file

五如果都正确，但是依旧接受是空

则把file类型变text,再重新选择file，重新选择文件上传，这大概是postman的bug吧，我刚刚遇到了，而且我uId是，2      接受了的时候莫名多了一个逗号，再这个一顿瞎几把操作之后就正常了
