没有找到适用于请求类型[Java.util.linkedhashmap]和内容类型[Multipart/form-dat

Question

i试图集成文件上传服务，该服务已注册为Eureka Discovery Infrastructure。

我的服务，说/myfile/上传的6个参数以下是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"

我已经为此服务创建了一个客户端接口，以下是我创建的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);
}

要提供编码器，我在下面添加了编码器：

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

我仍然有所有三种方法的例外：

上载：

无法编写请求：找不到适合的httpmessageconverter 请求类型[Java.io.file]和内容类型[Multipart/form-data]

uploadusting1：

无法编写请求：找不到适合的httpmessageconverter 请求类型[java.util.linkedhashmap]和内容类型 [Multipart/form-data]

uploadusting2：

所需请求零件"文件"不存在

请建议

现在似乎已经解决了这个问题，当我升级到3.4.1时，我正在使用2.0.x版本的版本。
