优化Java客户端HTTPS连接

我正在尝试通过 SSL 与 RESTful API 进行通信。整个客户端应用程序依赖于一个基本的连接方法，看起来像这样，

URL url = null;
       HttpsURLConnection connection = null;
       BufferedReader bufferedReader = null;
       InputStream is = null;

       try {
                url = new URL(TARGET_URL);

                HostnameVerifier hv = new HostnameVerifier() {
                     public boolean verify(String urlHostName, SSLSession session) {
                       return true;
                     }
                };

                HttpsURLConnection.setDefaultHostnameVerifier(hv);
                connection = (HttpsURLConnection) url.openConnection();

                connection.setRequestMethod(requestType);
                connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
                connection.setRequestProperty("Content-Language", "en-US");
                connection.setSSLSocketFactory(sslSocketFactory);

                is = connection.getInputStream();

                bufferedReader = new BufferedReader(new InputStreamReader(is));
                String line;
                StringBuffer lines = new StringBuffer();

                while ((line = bufferedReader.readLine()) != null) {
                    lines.append(line).append(LINE_BREAKER);
                }
                return lines.toString();
       } catch (Exception e) {
           System.out.println("Exception is :"+e.toString());
           return e.toString();
       }
     }

这很好用，但是有更有效的方法吗？我们尝试过 Apache HTTPClient。它有一个非常简单的 API，但是当我们将上述代码与 Apache HTTPClient 和 YourKit 的性能进行比较时，后者创建的对象比第一个更多。我该如何优化这个？

I'm trying to communicate with a RESTful API over SSL. The whole client application relies on a basic connection method which looks something like this

URL url = null;
       HttpsURLConnection connection = null;
       BufferedReader bufferedReader = null;
       InputStream is = null;

       try {
                url = new URL(TARGET_URL);

                HostnameVerifier hv = new HostnameVerifier() {
                     public boolean verify(String urlHostName, SSLSession session) {
                       return true;
                     }
                };

                HttpsURLConnection.setDefaultHostnameVerifier(hv);
                connection = (HttpsURLConnection) url.openConnection();

                connection.setRequestMethod(requestType);
                connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
                connection.setRequestProperty("Content-Language", "en-US");
                connection.setSSLSocketFactory(sslSocketFactory);

                is = connection.getInputStream();

                bufferedReader = new BufferedReader(new InputStreamReader(is));
                String line;
                StringBuffer lines = new StringBuffer();

                while ((line = bufferedReader.readLine()) != null) {
                    lines.append(line).append(LINE_BREAKER);
                }
                return lines.toString();
       } catch (Exception e) {
           System.out.println("Exception is :"+e.toString());
           return e.toString();
       }
     }

This works well, but is there a more efficient way? We've tried Apache HTTPClient. It has an awesomely simple API but when we compared the performance of the above code vs Apache HTTPClient with YourKit, the latter one was creating more objects than the first. How do I optimize this?

我使用过 HTTPClient （但不适用于 HTTPS），但我认为这适用于您的情况。建议为您的服务器创建一个 HTTPClient，并为每个调用创建一个新的 HTTPGet 对象。您需要指定多线程客户端连接管理器，并在初始化 HTTPClient 时指定为每个主机分配适当数量的连接以及最大总连接数。

您还可以尝试使用 HttpCore 而不是 HttpClient。 HttpCore 是一组基于 HttpClient 的 HTTP 传输组件。它专门针对低内存占用和性能进行了优化。它缺乏 HttpClient 提供的更高级别的 HTTP 功能（连接管理、cookie 和状态管理、身份验证），但在内存利用率方面应该非常高效。
