What is the configuration of uploading pictures on FeignMultipartSupportConfig?
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!
FeignMultipartSupportConfig上传图片配置在对应的boot项目上关闭全局的上传图片的配置@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); }}在目标feign上面添加@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。
对应配置文件的代码@Configurationpublic 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 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 data = Collections.singletonMap("imgList", object); super.encode(data, MAP_STRING_WILDCARD, template); return; } } super.encode(object, bodyType, template); }}如何使用Feign上传图片添加依赖，支持SpringEncoder io.github.openfeign.form feign-form 3.4.1 io.github.openfeign.form feign-form-spring 3.4.1 将SpringFormEncoder的默认处理
encoder配置为SpringEncoder
@Configurationpublic class FeignMultipartSupportConfig { @Bean public Encoder multipartFormEncoder(ObjectFactory messageConverters) { return new SpringFormEncoder(new SpringEncoder(messageConverters)); }}编写client@FeignClient(value = "****", fallbackFactory = UploadClientFallbackFactory.class , configuration = FeignMultipartSupportConfig.class)public interface UploadClient { /** * 上传图片文件 * * @param file * @return */ @PostMapping(value = "/tbk/feedback/upload", produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}, consumes = MediaType.MULTIPART_FORM_DATA_VALUE) BaseResponse uploadImage(@RequestPart("file") MultipartFile file);}以上是"FeignMultipartSupportConfig上传图片配置方式是什么"这篇文章的所有内容，感谢各位的阅读!希望分享的内容对大家有帮助，更多相关知识，欢迎关注行业资讯频道!
