Springboot Feign文件上传

服务提供者

@SpringBootApplication
public 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);
}
}

1.feign相关的依赖

<dependency>
<groupId>io.github.openfeign.form</groupId>
<artifactId>feign-form</artifactId>
<version>3.0.3</version>
</dependency>
<dependency>
<groupId>io.github.openfeign.form</groupId>
<artifactId>feign-form-spring</artifactId>
<version>3.0.3</version>
</dependency>

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<String> uppic(@RequestPart(value = "file")MultipartFile file, @RequestParam Map<String,Object> 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
