本文详细介绍了如何在Java中使用MultipartFile接口处理文件上传，包括上传步骤、常见问题及解决策略，帮助开发者掌握文件上传的核心技术。

public static void main2(String[] args) {
    ExecutorService fixedThreadPool = Executors.newFixedThreadPool(10);
    try {
      String filepath = "/XX/XX1.ipa";//D盘下的file文件夹的目录
      File file = new File(filepath);//File类型可以是文件也可以是文件夹
      File pdf = file;

      FileInputStream fileInputStream = null;
      fileInputStream = new FileInputStream(pdf);

      MultipartFile multipartFile = new MockMultipartFile(pdf.getName(), pdf.getName(),
          ContentType.APPLICATION_OCTET_STREAM.toString(), fileInputStream);
      // 文件路径
      File apkFile = new File("/XX/xx1" + File.separator + "test");
      FileUtils.copyInputStreamToFile(multipartFile.getInputStream(), apkFile);
      HttpResponse httpFileUploadRequest = null;
      Map<String, String> resultMap = new HashMap<>();
      String html = "";
      // 参数
//      JSONObject token = getToken();
      JSONObject jsonObject1 = new JSONObject();
      jsonObject1.put("test1", "tt");
      jsonObject1.put("test2", "tt");
      HashMap<String, Object> paramMaps = new HashMap<>();
      paramMaps.put("param", jsonObject1);
      paramMaps.put("tt1", new File(apkFile.getAbsolutePath()));

      // header
      HashMap<String, String> headersMaps = new HashMap<>();
      try {
        httpFileUploadRequest = com.bangcle.app.utils.HttpUtils.httpFileUploadRequest(
            "http://xx.xx.xx.xxx:8080" + "/test1", paramMaps, headersMaps, null, null,
            null,
            null);
        JSONObject result = JSONObject
            .parseObject(httpFileUploadRequest.html());
        System.out.println(result);
      } catch (Exception e) {
        logger.error("上传文件时异常,文件名:{}", e, "file.getAbsolutePath()");
        resultMap.put(ResultCode.FAIL, "上传失败");
      }
      System.out.println("1");
    } catch (Exception e) {
      System.out.println(e.getMessage());

    }
  }
