找不到適合請求類型 [java.util.LinkedHashMap] 和內容類型 [multipart/form-data] 的 HttpMessageConverter

Question

我試圖集成一個文件上傳服務，該服務已在 Eureka 發現基礎設施中注冊。

我的服務，說 /myfile/upload 有以下 6 個參數，下面是 YML：

/myfile/upload:
      put:
         operationId: "uploadUsingPUT"
         consumes:
         - "multipart/form-data"
         produces:
         - "*/*"
         parameters:
         - name: "file"
           in: "formData"
           required: true
           type: "file"
         - name: "filename"
           in: "formData"
           required: true
           type: "string"
         - name: "path"
           in: "formData"
           required: true
           type: "string"
         - name: "header1"
           in: "header"
           required: true
           type: "string"
         - name: "header2"
           in: "header"
           required: false
           type: "string"
           allowEmptyValue: true
         responses:
            200:
               description: "OK"
            400:
               description: "Bad Request"

我為此服務創建了一個客戶端接口，下面是我創建的 API：

import java.io.File;
import java.util.Map;
import org.springframework.util.MultiValueMap;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RequestPart;

@org.springframework.cloud.netflix.feign.FeignClient(value = "SERVICE-NAME", configuration = {
  com.MyConfiguration.class})
public interface UploadControllerAPINew extends ApiClient.Api {

  @RequestMapping(value = "/myfile/upload",
    method = RequestMethod.PUT,
    produces = "*/*",
    consumes = "multipart/form-data"
  )
  FileUploadResponse uploadUsingPUT(@RequestPart("file") File file,
    @RequestParam("filename") String filename, @RequestParam("path") String path,
    @RequestHeader("header1") String header1,
    @RequestHeader("header2") String header2);


  @RequestMapping(value = "/myfile/upload",
    method = RequestMethod.PUT,
    produces = "*/*",
    consumes = "multipart/form-data"
  )
  FileUploadResponse uploadUsingPUT1(@RequestBody Map<String, ?> formParams,
    @RequestHeader("header1") String header1,
    @RequestHeader("header2") String header2);

  @RequestMapping(value = "/myfile/upload",
    method = RequestMethod.PUT,
    produces = "*/*",
    consumes = "multipart/form-data"
  )
  FileUploadResponse uploadUsingPUT2(@RequestPart("file") byte[] file,
    @RequestParam("filename") String filename, @RequestParam("path") String path,
    @RequestHeader("header1") String header1,
    @RequestHeader("header2") String header2);

}

為了給它提供一個編碼器，我在下面添加了編碼器：

@Bean
  public Encoder feignEncoder() {
    ObjectFactory<HttpMessageConverters> objectFactory = () ->
      new HttpMessageConverters(new FormHttpMessageConverter());
    // return new SpringEncoder(objectFactory);
    return new FormEncoder(new SpringEncoder(objectFactory));
  }

我仍然遇到所有三種方法的例外情況：

上傳使用PUT：

無法寫入請求：找不到適合請求類型 [java.io.File] 和內容類型 [multipart/form-data] 的 HttpMessageConverter

上傳使用PUT1：

無法寫入請求：找不到適合請求類型 [java.util.LinkedHashMap] 和內容類型 [multipart/form-data] 的 HttpMessageConverter

上傳使用PUT2：

所需的請求部分“文件”不存在

請建議

這個問題現在似乎已經解決了，我在 2.0.x 版本的 feign-form 上，當我升級到 3.4.1 時它開始工作了。
