将json数据发布到URL中时出错

我试图推送json数据，它与以下代码一起工作，但是，当我直接发送json数据时无法获得所需结果，表示如果用String input = jsonString;将json数据发布到URL中时出错

我的JSON字符串构建为：

ArrayList <ContactData> documents; 
Gson g = new Gson(); 
String jsonString = g.toJson(documents);

然后通过JSON字符串我的方法

private void pushDataToClientURL(String clientURL, String jsonString) 
     { 
      try { 

       log.debug("starting pushing data to Client URL"); 

       URL targetUrl = new URL(clientURL); 

       HttpURLConnection httpConnection = (HttpURLConnection) targetUrl.openConnection(); 
       httpConnection.setDoOutput(true); 
       httpConnection.setRequestMethod("POST"); 
       httpConnection.setRequestProperty("Content-Type", "application/json"); 
       OutputStream outputStream = httpConnection.getOutputStream(); 
      ##line1 String input ="{\"statusCode\":1,\"type\":\"Liam\",\"age\":22,\"value\":\"Marco\"}"; 

       outputStream.write(input.getBytes()); 
       outputStream.flush(); 

       if (httpConnection.getResponseCode() != 200) { 
        throw new RuntimeException("Failed : HTTP error code : " 
          + httpConnection.getResponseCode()); 
       } 

       BufferedReader responseBuffer = new BufferedReader(new InputStreamReader(
         (httpConnection.getInputStream()))); 

       String output; 

       log.debug("Output from Server:\n"); 

       while ((output = responseBuffer.readLine()) != null) { 
        System.out.println(output); 
       } 

       httpConnection.disconnect(); 

      } catch (MalformedURLException e) { 

       e.printStackTrace(); 

      } catch (IOException e) { 

       e.printStackTrace(); 

      } 

     }

这是我的休息服务

@POST 
     @Path("/dataPosting") 
     @Consumes(MediaType.APPLICATION_JSON) 
     public Response consumeJSON(ContactData bean){ 

      String result = bean.toString(); 

      return Response.status(200).entity(result).build(); 
     } 

    Getting error 


Exception in thread "Thread-3" java.lang.RuntimeException: Failed : HTTP error code : 400 
    at com.rest.test.profiling.ProfilingDataPushJOB.pushDataToClientURL(ProfilingDataPushJOB.java:127) 
    at com.rest.test.profiling.ProfilingDataPushJOB.run(ProfilingDataPushJOB.java:93) 
    at java.lang.Thread.run(Thread.java:745)

如果这将有URL问题，这将无法与我在这里粘贴的书面代码，它不仅工作时，我正在替换## line1分配与JSON字符串手段没有“\”字符在我的字符串 – MAX

你用'StringEntity'试过了吗？并添加了'setContentType（“application/json”）'？ –

转换您的JSON字符串代码为http post请求提供字符串实体和setEntity。 StringEntity se = new StringEntity（jsonString）;
