Java Apache HttpAsyncClient读取响应？

}

private zcsresponse httPost（URI、对象对象、列表参数、映射头）{
HttpPost postRequest=新的HttpPost（uri）；
HttpResponse HttpResponse=null；
试一试{
addHeaders（postRequest，headers）；
addPostParams（postRequest、object、params）；
Future futureResponse=httpClient.execute（postRequest，null）；
httpResponse=futuresponse.get（）；
响应=**读取响应（httpResponse）**
}
私有字符串读取响应（HttpResponse响应）引发IOException{
BufferedReader rd=新的BufferedReader(
新的InputStreamReader（response.getEntity（）.getContent（））；
StringBuffer结果=新的StringBuffer（）；
字符串行=”；
而（（line=rd.readLine（））！=null）{
结果。追加（行）；
}
rd.close（）；
返回result.toString（）；
}

我对使用ApacheHTTPAsync客户端的代码有以下疑问

反应堆与NPoolingConnectionManager的作用是什么

目前，响应体是从post请求的流中读取的。并且没有使用NIO或非阻塞方式读取响应体。这是正确的方式吗

 private void init() {
   #Reactor 
   ioReactorConfig = IOReactorConfig.custom()                    
          .setIoThreadCount(Runtime.getRuntime().availableProcessors())
                            .setConnectTimeout(30000)
                            .setSoTimeout(30000)
                            .build();

   try {
       ioReactor = new DefaultConnectingIOReactor(ioReactorConfig);
   } catch (IOReactorException e) {
       e.printStackTrace();
       //TODO handle exception
    }
    connManager = new PoolingNHttpClientConnectionManager(ioReactor);
    httpClient = HttpAsyncClients.custom().setConnectionManager(connManager).build();

  private  ZCResponse httPost(URI uri, Object object,List<NameValuePair> params, Map<String,String> headers) {
        HttpPost postRequest = new HttpPost(uri);
        HttpResponse httpResponse = null;
        try {
            addHeaders(postRequest,headers);
            addPostParams(postRequest,object,params);
            Future<HttpResponse> futureResponse = httpClient.execute(postRequest, null);
            httpResponse = futureResponse.get();
            response = **readResponse(httpResponse);**
   }

private  String readResponse(HttpResponse response) throws IOException {
            BufferedReader rd = new BufferedReader(
                    new InputStreamReader(response.getEntity().getContent()));

            StringBuffer result = new StringBuffer();
            String line = "";
            while ((line = rd.readLine()) != null) {
                result.append(line);
            }
            rd.close();
            return result.toString();
        }
