这篇文章主要介绍FeignMultipartSupportConfig上传图片配置方式是什么，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
计算
安全
数据库
网络和加速
企业服务
@SpringBootApplication
@EnableCircuitBreaker
@EnableEurekaClient
@EnableFeignClients
@ComponentScan(excludeFilters = {@ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE,value = FeignMultipartSupportConfig.class)})
public class BootstrapApplication {
public static void main(String[] args) {
SpringApplication.run(BootstrapApplication.class, args);
}
}@FeignClient(name = "micro-picture", fallbackFactory = MicroPictureFactory.class, configuration = FeignMultipartSupportConfig.class)
public interface MicroPictureClient {
@RequestMapping(value = { "/picture/common/upload/{commonKey}" }, method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public String upload(@RequestPart("image") MultipartFile image, @PathVariable("commonKey") Long commonKey);
}就可以实现对应的服务做图片的上传，针对的图片微服务就可以实现数据的额接收。
@Configuration
public class FeignMultipartSupportConfig {
@Bean
@Primary
@Scope("prototype")
public Encoder multipartFormEncoder() {
return new FeignSpringFormEncoder();
}
@Bean
public feign.Logger.Level multipartLoggerLevel() {
return feign.Logger.Level.FULL;
}
}package com.zhht.config;
import feign.RequestTemplate;
import feign.codec.EncodeException;
import feign.codec.Encoder;
import feign.form.ContentType;
import feign.form.FormEncoder;
import feign.form.MultipartFormContentProcessor;
import feign.form.spring.SpringManyMultipartFilesWriter;
import feign.form.spring.SpringSingleMultipartFileWriter;
import org.springframework.web.multipart.MultipartFile;
import java.lang.reflect.Type;
import java.util.Collections;
import java.util.Map;
public class FeignSpringFormEncoder extends FormEncoder {
public FeignSpringFormEncoder() {
this(new Default());
}
public FeignSpringFormEncoder(Encoder delegate) {
super(delegate);
MultipartFormContentProcessor processor = (MultipartFormContentProcessor) this
.getContentProcessor(ContentType.MULTIPART);
processor.addWriter(new SpringSingleMultipartFileWriter());
processor.addWriter(new SpringManyMultipartFilesWriter());
}
public void encode(Object object, Type bodyType, RequestTemplate template) throws EncodeException {
if (bodyType.equals(MultipartFile.class)) {
MultipartFile file = (MultipartFile) object;
if (file != null) {
Map<String, Object> data = Collections.singletonMap("image", object);
super.encode(data, MAP_STRING_WILDCARD, template);
return;
}
} else if (bodyType.equals(MultipartFile[].class)) {
MultipartFile[] file = (MultipartFile[]) object;
if (file != null) {
Map<String, Object> data = Collections.singletonMap("imgList", object);
super.encode(data, MAP_STRING_WILDCARD, template);
return;
}
}
super.encode(object, bodyType, template);
}

@Configuration
public class FeignMultipartSupportConfig {
@Bean
public Encoder multipartFormEncoder(ObjectFactory<HttpMessageConverters> messageConverters) {
return new SpringFormEncoder(new SpringEncoder(messageConverters));
}
}@FeignClient(value = "****",

)
public interface UploadClient {
/**

@PostMapping(value = "/tbk/feedback/upload",
produces = {MediaType.APPLICATION_JSON_UTF8_VALUE},
consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
BaseResponse<String> uploadImage(@RequestPart("file") MultipartFile file);
