2.MultipartSupportConfig configuration class

@Configuration
public class MultipartSupportConfig {
    @Autowired
    private ObjectFactory<HttpMessageConverters> messageConverters;

    @Bean
    public Encoder feignFormEncoder() {
        return new SpringFormEncoder(new SpringEncoder(messageConverters));
    }
}

 

3. backend interface transformation

Keywords consumes = MULTIPART_FORM_DATA_VALUE

/ ** 
* file upload interfaces 
* @param file upload 
* @date 2019-11-19 11:56:40 
** /

@PostMapping(value = "uploadExamTarget", consumes = MULTIPART_FORM_DATA_VALUE)
public JsonResult uploadExamTarget(@RequestBody MultipartFile file) {
    return new JsonResult(coreClient.uploadExamTarget(file));
}

 

4.FeignClient interfaces transformation

Introducing configuration class MultipartSupportConfig, and interfaces annotations consumes = MULTIPART_FORM_DATA_VALUE

@FeignClient(value = "core-server", configuration = MultipartSupportConfig.class)
public interface CoreClient {　　

　　/ ** 
　　 * Call core-server file upload service interfaces 
　　 * @param file upload 
 　　* @date 2019-11-19 11:56:40 
 　　** /

　　@RequestMapping(value = "/excel/uploadExamTarget", consumes = MULTIPART_FORM_DATA_VALUE) 
　　String uploadExamTarget(@RequestBody MultipartFile file);
}
