feign 客户端 同时支持文件上传和实体类作为参数接收

想让feign 客户端,这样既支持文件上传也支持实体类作为参数接收,  并放一个实体RequestBody 中.

一直报错:

2020-03-25 19:02:02.388 ERROR 3217 --- [ZXr4fAmWFX][io-22223-exec-1]         : system occur error: 

: Could not write request: no suitable HttpMessageConverter found for request type [] and content type [multipart/form-data]
	at (:143)
	at $(:372)
	at $(:224)
	at (:74)
	at $(:103)
	at .$(Unknown Source)

可以通过以下配置实现上述需求

1. 配置类

import ;
import ;
import ;
import ;
import ;
import ;

import ;
import ;

/**
 * 让 feign支持含MultiPart的dto 解析
 *
 * Created on 2020-03-25
 */
//@Configuration
public class MultiPartSupportConfiguration {

    @Autowired
    private ObjectFactory<HttpMessageConverters> messageConverters;

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

2. feign 客户端

@FeignClient(value = "XXX", url = "", configuration =
        )
public interface ClientDev  {
   @PostMapping(value = "/api/v1/",consumes = MediaType.MULTIPART_FORM_DATA_VALUE) Result uploadAvatar(@RequestBody DTO dto, @RequestHeader("X-Auth-Token") String token, @RequestHeader("X-User-Id") String uid);
}

 

类

@Data
public class DTO {

    private String username;
    private MultipartFile image;

}

这样既支持文件上传也支持实体类作为参数接收
