Spring Restful Webservice上传CSV

我想实现Java Spring Restful Webservice来上传和处理CSV文件，然后将记录插入到数据库中。Spring Restful Webservice上传CSV

由于我不是这方面的专家，我尝试了几个代码来构建Web服务及其客户端。但他们都失败了。

我目前使用的最后一个代码是：

Web服务类：

@RequestMapping(value = "/rest/file/upload", method = RequestMethod.POST) 
public @ResponseBody 
String uploadFileHandler(@RequestParam("name") String name, 
     @RequestParam("file") MultipartFile file) { 

    if (!file.isEmpty()) { 
     try { 
      byte[] bytes = file.getBytes(); 

      // Creating the directory to store file 
      String rootPath = System.getProperty("catalina.home"); 
      File dir = new File(rootPath + File.separator + "tmpFiles"); 
      if (!dir.exists()) 
       dir.mkdirs(); 

      // Create the file on server 
      File serverFile = new File(dir.getAbsolutePath() 
        + File.separator + name); 
      BufferedOutputStream stream = new BufferedOutputStream(
        new FileOutputStream(serverFile)); 
      stream.write(bytes); 
      stream.close(); 

      logger.info("Server File Location=" 
        + serverFile.getAbsolutePath()); 

      return "You successfully uploaded file=" + name; 
     } catch (Exception e) { 
      return "You failed to upload " + name + " => " + e.getMessage(); 
     } 
    } else { 
     return "You failed to upload " + name 
       + " because the file was empty."; 
    } 
}

而且客户端：

@Bean 
public static void main(String[] args) throws Exception { 
    Client fileUpload = new Client() ; 
     File file = new File("D:/hibernate.xml") ; 
     //Upload the file 
     fileUpload.executeMultiPartRequest("http://localhost:8080/SpringServiceMongoDB/rest/file/upload", 
       file, file.getName(), "File Uploaded :: Tulips.jpg") ; 
    } 


public void executeMultiPartRequest(String urlString, File file, String fileName, String fileDescription) throws Exception 
    { 
     HttpClient client = new DefaultHttpClient() ; 
     HttpPost postRequest = new HttpPost (urlString) ; 
     try 
     { 
      //Set various attributes 
      MultipartEntity multiPartEntity = new MultipartEntity() ; 
      multiPartEntity.addPart("fileDescription", new StringBody(fileDescription != null ? fileDescription : "")) ; 
      multiPartEntity.addPart("fileName", new StringBody(fileName != null ? fileName : file.getName())) ; 

      FileBody fileBody = new FileBody(file, "application/octect-stream") ; 
      //Prepare payload 
      multiPartEntity.addPart("attachment", fileBody) ; 

      //Set to request body 
      postRequest.setEntity(multiPartEntity) ; 

      //Send request 
      HttpResponse response = client.execute(postRequest) ; 

      //Verify response if any 
      if (response != null) 
      { 
       System.out.println(response.getStatusLine().getStatusCode()); 
      } 
     } 
     catch (Exception ex) 
     { 
      ex.printStackTrace() ; 
     } 
    }

但我总是收到格式不正确或内部服务器错误。

我试图用邮递员，但我也得到了以下错误：

任何帮助？

你可以尝试使用邮递员客户端执行'REST'调用吗？另外，你能分享异常的堆栈跟踪吗？ –

我已经编辑我的职务与邮差响应.. – Kareem

从堆栈跟踪看来，您还没有定义MultipartResolver。你可以尝试在你的一个组件类中添加以下两个bean定义吗？

@Bean 
public MultipartConfigElement multipartConfigElement() { 
    MultipartConfigFactory factory = new MultipartConfigFactory(); 
    factory.setMaxFileSize("500MB"); 
    factory.setMaxRequestSize("500MB"); 
    return factory.createMultipartConfig(); 
} 


@Bean 
public MultipartResolver multipartResolver() { 
    return new StandardServletMultipartResolver(); 
}

请注意，MaxFileSize和MaxRequestSize将视配置而改变。

我加入这个标签servlet的contxt.xml <豆类：豆类ID =“multipartResolver” 类=“org.springframework.web.multipart.commons.CommonsMultipartResolver” > < - 设定最大上传大小 - > <豆：属性名= “maxUploadSize” 值= “100000”/> 现在加入您的建议的方法后，我得到类型的javax。 servlet.MultipartConfigElement无法解析。它是从必要的间接引用的。class files 非常感谢您的支持 – Kareem

您可否请更新有问题的新异常的xml文件和堆栈跟踪？谢谢 –

我已经添加了你要求的日志 – Kareem
