feign接口上传文件遇到的问题

1、调用者

@RestControllerpublicclasstestFeign{@Autowired
    ProducerFeign producerFeign;@PostMapping("/testFeign")public ResulttestFeign(@RequestParam("file") MultipartFile file,@RequestParam("startRow")Integer startRow,@RequestParam("endRow")Integer endRow){
        List<Map<String, Object>> maps= producerFeign.getFile(file, startRow, endRow);return Result.success(maps);}}

2、被调用者

@RestControllerpublicclassProducerController{@Autowired
    ExcelParseService excelParseService;@PostMapping(path="/getFileInfo")//RequestPart这里要用RequestPart接收参数public List<Map<String, Object>>getFile(@RequestPart(required=true,name="file") MultipartFile file,@RequestParam("startRow")Integer startRow,@RequestParam("endRow")Integer endRow){
        List<Map<String, Object>> result= excelParseService.parse(file, startRow, endRow);return result;}}

3、Feign接口

@FeignClient(name="producer")//,configuration = FeignMultipartSupportConfig.class网上找到这样的配置去解决方案但是不加这个也能成功publicinterfaceProducerFeign{@PostMapping(value="/getFileInfo",consumes={MediaType.MULTIPART_FORM_DATA_VALUE})//,consumes = {MediaType.MULTIPART_FORM_DATA_VALUE}这也是必须要加的，将调用此接口的请求参数转换成multipart/form-data格式
    List<Map<String, Object>>getFile(@RequestPart(required=true,name="file") MultipartFile file,//也要用@RequestPart接受参数@RequestParam("startRow") Integer startRow,@RequestParam("endRow") Integer endRow);}
