springboot踩坑日记——Feign传递MultipartFile


创建配置类

package com.thecarevoice.frontend.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.context.annotation.Scope;

import feign.codec.Encoder;
import feign.form.spring.SpringFormEncoder;

/**
* @ClassName FeignMultipartSupportConfig
* @Description TODO
* @Author yanqing.liu
* @Date 2022/5/12 2:06 下午
* @Version 1.0
*/
@Configuration
public class FeignMultipartSupportConfig {
@Bean
@Primary
@Scope("prototype")
public Encoder multipartFormEncoder() {
return new SpringFormEncoder();
}

@Bean
public feign.Logger.Level multipartLoggerLevel() {
return feign.Logger.Level.FULL;
}

}

api

@PostMapping("upload")
@ApiOperation("图片上传")
public ResultResponse<JSONObject> upload( @RequestParam("file") MultipartFile multipartFile){
return null
}

FeignClient

package com.thecarevoice.frontend.adaptor;

import com.alibaba.fastjson.JSONObject;
import com.thecarevoice.frontend.config.FeignMultipartSupportConfig;
import com.thecarevoice.frontend.response.ResultResponse;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestPart;
import org.springframework.web.multipart.MultipartFile;


/**
* @ClassName FoodController
* @Description TODO
* @Author yanqing.liu
* @Date 2022/5/10 5:49 下午
* @Version 1.0
*/
@FeignClient(value = "fileAdaptor",url="${health.data.adaptor.host}",configuration = FeignMultipartSupportConfig.class)
public interface FileAdaptor {

/**
* 上传食品图片
* @param multipartFile
* @return
*/
@RequestMapping(value = "/api/v1/food/upload",
produces = {MediaType.APPLICATION_JSON_VALUE},
consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
ResultResponse<JSONObject> upload(@RequestPart("file") MultipartFile multipartFile);
}
