Question

我使用Spring Integration实现了一个REST服务。当我尝试使用main函数手动访问服务时，它工作正常。我还使用谷歌浏览器中的REST客户端测试了该服务，并且运行良好。但是该服务将在WebSphere服务器上使用responseCode 404返回。因此，当我在更高的环境中部署代码时，我面临着这个问题。

  URL u = new URL("http://localhost:8080/MyApplication/testRestService");
  URLConnection uc = u.openConnection();
  HttpURLConnection connection = (HttpURLConnection) uc;

  connection.setDoOutput(true);
  connection.setDoInput(true);
  connection.setRequestMethod("POST");
  connection.setRequestProperty("Accept","*/*");      
  connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

  OutputStream out = connection.getOutputStream();
  Writer wout = new OutputStreamWriter(out);

  //helper function that gets a string from a dom Document
  String input = jsonInput;
  wout.write(input.getBytes());        
  wout.flush();
  wout.close();

  // Response
  int responseCode = connection.getResponseCode();

是依赖于服务器，所以它的回复代码为404？我们需要任何服务器端配置吗？

任何建议都将受到赞赏。

Answer 1

为什么对ContentType和URLConnection使用不同的httpClient？

请显示您的REST服务配置：404表示Not found。因此，您在请求中使用（或不使用）某些选项，使其与服务器RequestMapping不匹配。

我尝试使用Apache HTTP Client，现在代码正在使用WebSphere。我仍然无法找到java.net.HttpURLConnection无法在WebSphere上工作的原因。

请在下面找到我的更新代码：

DefaultHttpClient httpClient = null;
        HttpPost postRequest = null;
        StringEntity inputEntity = null;
        HttpResponse response = null;
        try{


            //RETREIVE WEB SERVICE URL FROM DB
            String callbackURL = "http://localhost:8080/MyApplication/testRestService";
            httpClient = new DefaultHttpClient();
            postRequest = new HttpPost(callbackURL);            
            String inputData = request.toString();

            inputEntity = new StringEntity(inputData);
            inputEntity.setContentType("application/x-www-form-urlencoded");
            postRequest.setEntity(inputEntity);

            response = httpClient.execute(postRequest);



            if (response.getStatusLine().getStatusCode() != 201 && response.getStatusLine().getStatusCode() != 200) {
                throw new RuntimeException("Failed : HTTP error code : "+ response.getStatusLine().getStatusCode());
            }

            //System.out.println("HTTP Response Code :"+response.getStatusLine().getStatusCode());
            LOGGER.debug("HTTP Response Code :"+response.getStatusLine().getStatusCode());

            httpClient.getConnectionManager().shutdown();
        }catch(IOException ex){
            ex.printStackTrace();
            throw ex;
        }finally{
            httpClient.getConnectionManager().shutdown();
            httpClient = null;
            postRequest = null;
            inputEntity = null;
            response = null;
        }

connection.getConnetion（）在WebSphere7
