本文介绍了一个使用Delphi进行多部分表单数据上传的例子，并展示了如何通过Java接收这些数据。Delphi端创建了多部分表单数据流并添加了必要的字段及文件，而Java端则检查请求是否为多部分请求并处理上传的文件。

delphi端：

var
    MutPartForm: TIdMultiPartFormDataStream;
    response: string;
    FHttp: Tidhttp;
begin
    FHttp := Tidhttp.Create(nil);
    FHttp.HandleRedirects := true;
    FHttp.AllowCookies := true;

    MutPartForm := TIdMultiPartFormDataStream.Create;
    MutPartForm.AddFormField('act', 'upload');
    MutPartForm.AddFormField('upcount', '1');
    MutPartForm.AddFormField('filepath', 'data');
    MutPartForm.AddFormField('databaseName', 'swgl');
    MutPartForm.AddFormField('billCode', '1DD-2020-08-01-0004');
   // MutPartForm.AddFormField('file1', 'filename="D:\exportPDF\1CG-2020-08-26-0001.pdf"');
    MutPartForm.AddFormField('Submit', 'Submit');
    MutPartForm.AddFile('file', 'D:\exportPDF\1CG-2020-08-26-0001.pdf', GetMIMETypeFromFile('D:\exportPDF\1CG-2020-08-26-0001.pdf'));
    try
        
        response := FHttp.Post('http://127.0.0.1:18080/PSSWeb/PDF/uploadPDF.do', MutPartForm);
        WinExec(pChar('chrome.exe --new-window http://127.0.0.1:18080/PSSWeb/supplier/bill/showPDF.pdf?fileName='+response),SW_SHOWNORMAL);
        ShellExecute(Handle,'open','chrome.exe',PChar('--new-window http://127.0.0.1:18080/PSSWeb/supplier/bill/showPDF.pdf?fileName='+response),'',SW_SHOWNORMAL);
       // Messagebox(0, PAnsiChar(response), 'ca', MB_OK);
    finally
        MutPartForm.Free;
        FHttp.Free;
    end;

java端:

CommonsMultipartResolver multipartResolver=new CommonsMultipartResolver(
                request.getSession().getServletContext());
		String meargeFile = "";
		if(multipartResolver.isMultipart(request))
        {
            //将request变成多部分request
            MultipartHttpServletRequest multiRequest=(MultipartHttpServletRequest)request;
            MultiValueMap<String,MultipartFile> fileMap =  multiRequest.getMultiFileMap();
            List<MultipartFile> files=fileMap.get("file");
            String reportFile = ""; 
            for (MultipartFile f : files) {
            	
            	reportFile = ps.InputStreamToFile(f.getInputStream());
            	
            }
           
            
        }
