Today, I will talk to you about how to implement the backflow of the SpringCloudFeign interface. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

Service provider

@ 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);}}

Client client

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

Service consumers

@ 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) {}}
