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);
}

 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);
}
