feign调用远程服务 并传输媒体类型

引包

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
    <version>2.2.0.RELEASE</version>
</dependency>

媒体文件feign支持config

@Configuration
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
public class FeignSupportConfig {

    private final ObjectFactory<HttpMessageConverters> messageConverters;

    @Bean
    public Encoder feignFormEncoder() {
        return new SpringFormEncoder(new SpringEncoder(messageConverters));
    }
}

写feignClient

package com.huatai.txasr.interfance;

import com.huatai.txasr.config.FeignSupportConfig;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

@FeignClient(name = "txasr" ,url = "https://******.com",configuration = FeignSupportConfig.class)
public interface PublicClientIface {

    @RequestMapping(method = RequestMethod.POST, value = "/xxxx/media/voice/xxxxx",consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    String publicUpload(@RequestParam(value = "access_token")String access_token, @RequestParam(value = "format")String format, @RequestParam(value = "voice_id")String voice_id,@RequestPart(value = "file") MultipartFile file);

}
