本文介绍如何使用Feign进行Multipart形式的图片上传配置，包括Feign客户端的配置、SpringFormEncoder的注入及日志级别设置，适用于需要处理文件上传请求的微服务架构。

package com.ph.wallet.otc.config;

import feign.form.spring.SpringFormEncoder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.context.annotation.Scope;

/**
 * 配置feign上传图片
 */
@Configuration
public class FeignMultipartSupportConfig {

    @Bean
    @Primary
    @Scope("prototype")
    public SpringFormEncoder multipartFormEncoder() {
        return new SpringFormEncoder();
    }

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

package com.ph.wallet.otc.sdk;

import com.ph.wallet.otc.config.FeignMultipartSupportConfig;
import com.ph.wallet.otc.sdk.impl.TransferServiceHystrix;
import org.springframework.cloud.netflix.feign.FeignClient;
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.multipart.MultipartFile;

import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RequestPart;
import org.springframework.web.multipart.MultipartFile;

import java.util.Map;

/**

@FeignClient(value="wallet-data", configuration=FeignMultipartSupportConfig.class)
public interface DataService {


    @RequestMapping(value="/file/OSSUploadFile", method = {RequestMethod.POST}, produces = {MediaType.APPLICATION_JSON_UTF8_VALUE},consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    Map<String, Object> upFileForApp(@RequestPart(value = "file") MultipartFile file);
