Spring Cloud Feign Client 上传文件

1、引入maven依赖

<dependency>  
	<groupId>io.github.openfeign.form</groupId>  
	<artifactId>feign-form-spring</artifactId>  
	<version>3.2.2</version>  
</dependency>  
<dependency>  
	<groupId>io.github.openfeign.form</groupId>  
	<artifactId>feign-form</artifactId>  
	<version>3.2.2</version>  
</dependency>

2、feign上传文件feign结构以及配置类

@FeignClient(name = "pms-rms",configuration = IFileUploadClient.MultipartSupportConfig.class)
public interface IFileUploadClient {
    /**
     * 根据条件查询集合
     * @param flFileupload
     * @return
     */
    @RequestMapping("/module/fileManage/fileManageFileUploadInfoDomainList")
    @ResponseBody
    public List<FileManageFileUploadInfoDomain> selectList(@RequestBody FileManageFileUploadInfoDomain flFileupload);


    /**
     * 上传文件增加到表中并返回集合信息
     * @param file
     * @param request
     * @return
     */
    @RequestMapping(method = RequestMethod.POST, value = "/module/fileManage/upload",produces = {MediaType.APPLICATION_JSON_UTF8_VALUE},consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    @ResponseBody
    public AjaxResult uploadFile(@RequestPart(value = "file") MultipartFile file, @RequestParam MultipartHttpServletRequest request);

    /**
     * 文件上传配置类
     */
    @Configuration
    class MultipartSupportConfig {
        @Autowired
        private ObjectFactory<HttpMessageConverters> messageConverters;

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