Springboot Feign文件上传

服务提供者

@SpringBootApplicationpublic class FeignUploadFirstApplication {  @RestController  public class UploadController {    @RequestMapping(value = "/uploadFile",method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)    public String handleFileUpload(@RequestPart(value = "file") MultipartFile file) {      return file.getOriginalFilename();    }  }  public static void main(String[] args) {    SpringApplication.run(FeignUploadFirstApplication.class, args);  }}

服务消费者

1.feign相关的依赖

      io.github.openfeign.form      feign-form      3.0.3              io.github.openfeign.form      feign-form-spring      3.0.3    

2.feign配置类

@Configurationpublic class FeignMultipartSupportConfig {    @Bean    public Encoder feignFormEncoder() {        return new SpringFormEncoder();    }}

3.feign调用接口 注解中加入配置类

@FeignClient(value = "xxx", configuration = FeignMultipartSupportConfig.class)public interface IUploadService {    /**     * 文件上传     * @param file 文件     * @return     */    @RequestMapping(value = "upload/uppic", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)    ResultModel uppic(@RequestPart(value = "file")MultipartFile file, @RequestParam Map map);}

4.上传接口

@RestControllerpublic class UploadController {  @Autowired   IUploadService uploadService;  @RequestMapping(value = "/uploadFile",method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)  public String handleFileUpload(@RequestPart(value = "file") MultipartFile file) {    return uploadService.uppic(file);  }}

文件上传 File 转 Multi

FileInputStream fileInputStream = new FileInputStream(file);MultipartFile multipartFile = new MockMultipartFile("file", file.getName(), ContentType.TEXT_PLAIN.toString(), fileInputStream);

• 注意：
  1. File 转 MultipartFile 中的第一个参数必须与服务提供者的接口参数一致，即@RequestPart中的value
