文件上傳

step1、jsp前端

<form action="<%=request.getContextPath()%>/index/uploadvideo" method="post" enctype="multipart/form-data">
    <input type="file" name="file" />
    <input class="btn btn-success fileinput-button" type="submit" value="上傳" />
</form>

step2、controller

@RequestMapping("/uploadvideo")
    public ModelAndView uploadVideo(HttpServletRequest request,@RequestParam(value="file",required=false) MultipartFile file){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("/backstage/handleresult");
        ResultVo<String> resultVo = new ResultVo<>();
        JceLog.info("上傳視頻--->");
        try {
            String fileName = file.getOriginalFilename();
            String extension = fileName.substring(fileName.lastIndexOf("."));

//        String savedFileName = java.util.UUID.randomUUID().toString() + extension;

//          String savedFileName = "index_video"+extension;
            String savedFileName = "index_video.mp4";
//          String folderPath = "D:\\tomcatStore\\gszw\\"+savedFileName;
            String folderPath = "/home/projectDeploy/inacg/store/gsyx/"+savedFileName;
            boolean uploadResult = FileUpload.doUploadFile(file, folderPath);
            if (uploadResult) {
                  resultVo.setIsSuccess(PARAM_SUCCESS);
                  resultVo.setMessage("視頻上傳成功,請到<a href='http://101.132.155.221:9090/Gsyx/'>首頁</a>查看");
            }else {
                  resultVo.setIsSuccess(PARAM_ERROR);
                  resultVo.setMessage("視頻上傳失敗,請重試!");
            }
            } catch (Exception e) {
                  // TODO: handle exception
                  resultVo.setIsSuccess(PARAM_ERROR);
            resultVo.setMessage("封面上傳異常,請確認選擇好要上傳的文件");
            }
        modelAndView.addObject("result", resultVo);
        return modelAndView;
    }

step3、配置文件

<!-- 配置文件上傳，如果沒有使用文件上傳可以不用配置，當然如果不配，那麼配置文件中也不必引入上傳組件包 --> 
<bean id="multipartResolver"
      class="org.springframework.web.multipart.commons.CommonsMultipartResolver">   
 <!-- 默認編碼 -->
<property name="defaultEncoding" value="utf-8" />
<!-- 文件大小最大值 -->
<property name="maxUploadSize" value="10485760000" />
<!-- 內存中的最大值 -->
<property name="maxInMemorySize" value="409600000" />
</bean>
