3、原因

服務消費者，需要設置方法返回值為Response

4、解決

將服務提供者的文件下載響應的響應體(文件內容)復制到服務消費者對外的文件下載響應體中

@FeignClient(value = "${feign.client.config.good-house-push.name}", url = "${feign.client.config.good-house-push.url}", path = "${feign.client.inner.path}", configuration = CatFeignConfiguration.class) public interface ITmallSyncEsfCommunityApi{@ApiOperation("根據批次號，下載同步二手房小區的錯誤日志列表")@GetMapping({"/api/tmall/syncEsfCommunity/logList/downloadError/{batchNo}"})Response downloadErrorLogListByBatchNo(@PathVariable(name = "batchNo") String batchNo); } @ApiOperation(value = "根據批次號，下載同步二手房小區的錯誤日志列表")@GetMapping("/cityopen/syncEsfCommunity/logList/downloadError/{batchNo}")void downloadErrorLogListByBatchNo(@PathVariable(name = "batchNo") String batchNo, HttpServletResponse response) {InputStream inputStream = null;try {Response serviceResponse = tmallSyncEsfCommunityApi.downloadErrorLogListByBatchNo(batchNo);Response.Body body = serviceResponse.body();inputStream = body.asInputStream();BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");response.setCharacterEncoding("utf-8");response.setHeader("Content-disposition", "attachment;filename*=utf-8''" + batchNo + ".xlsx");BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(response.getOutputStream());int length = 0;byte[] temp = new byte[1024 * 10];while ((length = bufferedInputStream.read(temp)) != -1) {bufferedOutputStream.write(temp, 0, length);}bufferedOutputStream.flush();bufferedOutputStream.close();bufferedInputStream.close();inputStream.close();} catch (IOException e) {e.printStackTrace();}}
