Question

我已经设置了两个

的应用程序

文件服务器（8000）
App server（4000）

两者都单独工作（使用Postman测试）。

当我从UI / Postman接收文件并将数据表格形式发送到App服务器并使用Rest模板传输到Document并将表格数据传输到文件服务器时，会出现问题。同时App服务器给我一个以下错误。

15:33:56.360 [http-nio-4206-exec-10] DEBUG o.s.web.client.RestTemplate - Created POST request for "http://localhost:8000/docserver/api/webservicegetway/savefile"

并在doc服务器上关注问题

我的RestWebservice代码低于一： -

App Server： -

@RequestMapping(value = "/uploadTest", method = RequestMethod.POST,consumes=MediaType.MULTIPART_FORM_DATA_VALUE)
private WebserviceResultSet fileUpload_Test( @RequestParam( "file" ) MultipartFile file,@RequestParam( "filename" ) String filesource,@RequestParam( "filepassword" ) String filepassword, Model p_model ) throws IOException, URISyntaxException {

    WebserviceResultSet result=new WebserviceResultSet();  
    if ( file.isEmpty() ) {
        result.addErrormessage("Empty or Corrupted file upload");
        return result;
    }

            byte[] l_bytes = file.getBytes();
            Path l_path = Paths.get("C:\\Eclipse_workspace\\"+ file.getOriginalFilename() );
            Path p=Files.write( l_path, l_bytes );



            DocServerService docServerService=new DocServerService();
            docServerService.transferFileToDocServer(file, filesource, filepassword);



    return result;

}

Doc Server： -

@RequestMapping(value = "savefile", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
private WebserviceResultSet saveFile(@RequestParam("file") MultipartFile p_file,
        @RequestParam("filename") String filename,
        @RequestParam("filepassword") String filepassword, Model p_model,
        HttpServletRequest request) {

    WebserviceResultSet savefile = new WebserviceResultSet();

    String applicationctxpath = request.getRealPath(request.getContextPath());

    String directoryName = applicationctxpath + File.separator +ROOT_PATH + File.separator +filename;

    File directory = new File(directoryName);
    if (!directory.exists()) {
        directory.mkdirs();

    }

    try {

        byte[] l_bytes = p_file.getBytes();
        Path l_path = Paths
                .get(directoryName + File.separator +  p_file.getOriginalFilename());
        Files.write(l_path, l_bytes);

        savefile.setStatus(com.main.general.ResultConstent.STATUS_OK);


    } catch (IOException e) {

        savefile.addErrormessage("Exception occured while saving file in Doc Server");

    }

    return savefile;
}

使用两个应用程序之间的RestTemplate在post请求中传输文件和表单数据
