Feign的方法参数使用MultipartFile
Feign的方法参数使用MultipartFile，不能直接用，需要做一些配置。
依赖包：
<dependency>
<groupId>io.github.openfeign.form</groupId>
<artifactId>feign-form</artifactId>
<version>3.8.0</version>
</dependency>
<dependency>
<groupId>io.github.openfeign.form</groupId>
<artifactId>feign-form-spring</artifactId>
<version>3.8.0</version>
</dependency>
或者是直接用 spring-cloud-starter-openfeign。
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
服务提供者
MultipartFile 使用 @RequestPart 修饰。
还需要添加一个消费者类型：consumes = MediaType.MULTIPART_FORM_DATA_VALUE
@RestController
@RequestMapping("/xx")
public class FileController {
@PostMapping(value = "/uploadFile", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public Response uploadFile(@RequestPart("file") MultipartFile multipartFile, @RequestParam("name") String name) {
//....
}
}
配置Feign的Encoder
@Configuration
public class FeignMultipartConfig {
@Autowired
private ObjectFactory<HttpMessageConverters> messageConverters;
@Bean
@Primary
@Scope("prototype")
public Encoder feignEncoder() {
return new SpringFormEncoder(new SpringEncoder(messageConverters));
}
}
FeignClient
FeignClient 指定 configuration = FeignMultipartConfig.class
consumes = MediaType.MULTIPART_FORM_DATA_VALUE
如下所示。
@FeignClient(name = "xx",configuration = FeignMultipartConfig.class)
@RequestMapping("/xx")
public interface FeignService {
@PostMapping(value = "/uploadFile", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
Response uploadFile(@RequestPart("file") MultipartFile multipartFile, @RequestParam("name") String name);
}
服务消费者
MultipartFile用 @RequestPart 修饰即可。
@RestController
@Slf4j
public class FeignController {
@Autowired
private FeignService feignService;
@RequestMapping(value = "/uploadFile")
public String fileUpload(@RequestPart("file") MultipartFile file, @RequestParam("name") String name ) {
log.info("文件上传---fileName---{}",file.getOriginalFilename());
return feignService.uploadFile(file,name);
}
}
