Spring Cloud Feign接口返回流的实现

@GetMapping("/{id}")  public void queryJobInfoLogDetail(@PathVariable("id") Long id, HttpServletResponse response) {    File file = new File("xxxxx");    InputStream fileInputStream = new FileInputStream(file);    OutputStream outStream;    try {      outStream = response.getOutputStream();      byte[] bytes = new byte[1024];      int len = 0;      while ((len = fileInputStream.read(bytes)) != -1) {        outStream.write(bytes, 0, len);      }      fileInputStream.close();      outStream.close();      outStream.flush();    } catch (IOException e) {      log.error("exception", e);    }  }

@GetMapping(value = "/{id}", consumes = MediaType.APPLICATION_JSON_UTF8_VALUE)  feign.Response queryJobInfoLogDetail(@PathVariable("id") Long id);

  @GetMapping("/{id}")  public void queryJobInfoLogInfoList(@PathVariable("id") Long id, HttpServletResponse servletResponse) {    Response response = apiServices.queryJobInfoLogDetail(id);    Response.Body body = response.body();    InputStream fileInputStream = null;    OutputStream outStream;    try {      fileInputStream = body.asInputStream();      outStream = servletResponse.getOutputStream();      byte[] bytes = new byte[1024];      int len = 0;      while ((len = fileInputStream.read(bytes)) != -1) {        outStream.write(bytes, 0, len);      }      fileInputStream.close();      outStream.close();      outStream.flush();    } catch (Exception e) {    }  }
