public String handleFileUpload(@RequestPart(value = "file") MultipartFile file) {
return file.getOriginalFilename();
}
}
public static void main(String[] args) {
SpringApplication.run(FeignUploadFirstApplication.class, args);

2.feign配置类
@Configuration
public 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
@RestController
public 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:
- 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
