Java 所需的MultipartFile参数'；文件'；不存在-MultipartyEntityBuilder

我试图使用httpclient（Post）将多端口发送到正在服务器中运行的spring模块。因此，这就是RESTfulWeb服务。但是我的代码抛出了错误。你能帮帮我吗

我已经试过了：

HTTPCLIENT文件：（POST请求）

弹簧控制器：

@RequestMapping(value="/student/addimage",method=RequestMethod.POST,headers = "content-type=multipart/form-data")
public  void Addingimage(@RequestParam(value="files") MultipartFile files)
{
 //System.out.println(files.isEmpty());
}

输出：

---

所需的MultipartFile参数“files”不存在

我认为ContentType存在问题

您的控制器找不到任何名为“files”的参数

试试这个

public class MultiFile {
    public static void main(String args[]) throws ClientProtocolException, IOException
    {
        CloseableHttpClient httpclient = HttpClients.createDefault();
        HttpPost httppost = new HttpPost("http://localhost:8080/RESTapi/student/addimage");
        File file = new File("/Users/prabhu-pt3030/Desktop/eclipse-workspace-new/testing/target/classes/tes/javaFile123.txt");
        MultipartEntityBuilder entitybuilder = MultipartEntityBuilder.create();
        FileBody filebody = new FileBody(file, ContentType.DEFAULT_BINARY);
        entitybuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        entitybuilder.addPart("files", filebody);
        HttpEntity mutiPartHttpEntity = entitybuilder.build();  
        httppost.setEntity(mutiPartHttpEntity); 
        HttpResponse httpresponse = httpclient.execute(httppost);
    }
}

请参阅此处了解

否！我也犯了同样的错误。我将contentype更改为默认的\u二进制，甚至使用deafult\u文本。但仍然得到同样的错误

public class MultiFile {
    public static void main(String args[]) throws ClientProtocolException, IOException
    {
        CloseableHttpClient httpclient = HttpClients.createDefault();
        HttpPost httppost = new HttpPost("http://localhost:8080/RESTapi/student/addimage");
        File file = new File("/Users/prabhu-pt3030/Desktop/eclipse-workspace-new/testing/target/classes/tes/javaFile123.txt");
        MultipartEntityBuilder entitybuilder = MultipartEntityBuilder.create();
        FileBody filebody = new FileBody(file, ContentType.DEFAULT_BINARY);
        entitybuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        entitybuilder.addPart("files", filebody);
        HttpEntity mutiPartHttpEntity = entitybuilder.build();  
        httppost.setEntity(mutiPartHttpEntity); 
        HttpResponse httpresponse = httpclient.execute(httppost);
    }
}
