由于项目中有用到HttpClient异步发送大量http请求，所以做已记录
思路：使用HttpClient连接池，多线程
public class HttpAsyncClient { private static int socketTimeout = 500;// 设置等待数据超时时间0.5秒钟 根据业务调整 private static int connectTimeout = 2000;// 连接超时 private static int poolSize = 100;// 连接池最大连接数 private static int maxPerRoute = 100;// 每个主机的并发最多只有1500 private static int connectionRequestTimeout = 3000; //从连接池中后去连接的timeout时间 // http代理相关参数 private String host = ""; private int port = 0; private String username = ""; private String password = ""; // 异步httpclient private CloseableHttpAsyncClient asyncHttpClient; // 异步加代理的httpclient private CloseableHttpAsyncClient proxyAsyncHttpClient; public HttpAsyncClient() { try { this.asyncHttpClient = createAsyncClient(false); this.proxyAsyncHttpClient = createAsyncClient(true); } catch (Exception e) { e.printStackTrace(); } } public CloseableHttpAsyncClient createAsyncClient(boolean proxy) throws KeyManagementException, UnrecoverableKeyException, NoSuchAlgorithmException, KeyStoreException, MalformedChallengeException, IOReactorException { RequestConfig requestConfig = RequestConfig.custom() .setConnectionRequestTimeout(connectionRequestTimeout) .setConnectTimeout(connectTimeout) .setSocketTimeout(socketTimeout).build(); SSLContext sslcontext = SSLContexts.createDefault(); UsernamePasswordCredentials credentials = new UsernamePasswordCredentials( username, password); CredentialsProvider credentialsProvider = new BasicCredentialsProvider(); credentialsProvider.setCredentials(AuthScope.ANY, credentials); // 设置协议http和https对应的处理socket链接工厂的对象 Registry<SchemeIOSessionStrategy> sessionStrategyRegistry = RegistryBuilder .<SchemeIOSessionStrategy> create() .register("http", NoopIOSessionStrategy.INSTANCE) .register("https", new SSLIOSessionStrategy(sslcontext)) .build(); // 配置io线程 IOReactorConfig ioReactorConfig = IOReactorConfig.custom().setSoKeepAlive(false).setTcpNoDelay(true) .setIoThreadCount(Runtime.getRuntime().availableProcessors()) .build(); // 设置连接池大小 ConnectingIOReactor ioReactor; ioReactor = new DefaultConnectingIOReactor(ioReactorConfig); PoolingNHttpClientConnectionManager conMgr = new PoolingNHttpClientConnectionManager( ioReactor, null, sessionStrategyRegistry, null); if (poolSize > 0) { conMgr.setMaxTotal(poolSize); } if (maxPerRoute > 0) { conMgr.setDefaultMaxPerRoute(maxPerRoute); } else { conMgr.setDefaultMaxPerRoute(10); } ConnectionConfig connectionConfig = ConnectionConfig.custom() .setMalformedInputAction(CodingErrorAction.IGNORE) .setUnmappableInputAction(CodingErrorAction.IGNORE) .setCharset(Consts.UTF_8).build(); Lookup<AuthSchemeProvider> authSchemeRegistry; authSchemeRegistry = RegistryBuilder .<AuthSchemeProvider> create() .register(AuthSchemes.BASIC, new BasicSchemeFactory()) .register(AuthSchemes.DIGEST, new DigestSchemeFactory()) .register(AuthSchemes.NTLM, new NTLMSchemeFactory()) .register(AuthSchemes.SPNEGO, new SPNegoSchemeFactory()) .register(AuthSchemes.KERBEROS, new KerberosSchemeFactory()) .build(); conMgr.setDefaultConnectionConfig(connectionConfig); if (proxy) { return HttpAsyncClients.custom().setConnectionManager(conMgr) .setDefaultCredentialsProvider(credentialsProvider) .setDefaultAuthSchemeRegistry(authSchemeRegistry) .setProxy(new HttpHost(host, port)) .setDefaultCookieStore(new BasicCookieStore()) .setDefaultRequestConfig(requestConfig).build(); } else { return HttpAsyncClients.custom().setConnectionManager(conMgr) .setDefaultCredentialsProvider(credentialsProvider) .setDefaultAuthSchemeRegistry(authSchemeRegistry) .setDefaultCookieStore(new BasicCookieStore()).build(); } } public CloseableHttpAsyncClient getAsyncHttpClient() { return asyncHttpClient; } public CloseableHttpAsyncClient getProxyAsyncHttpClient() { return proxyAsyncHttpClient; } }
public class HttpClientFactory { private static HttpAsyncClient httpAsyncClient = new HttpAsyncClient(); private HttpClientFactory() { } private static HttpClientFactory httpClientFactory = new HttpClientFactory(); public static HttpClientFactory getInstance() { return httpClientFactory; } public HttpAsyncClient getHttpAsyncClientPool() { return httpAsyncClient; } }
public void sendThredPost(List<FaceBookUserQuitEntity> list,String title,String subTitle,String imgUrl){ if(list == null || list.size() == 0){ new BusinessException("亚洲查询用户数据为空"); } int number = list.size(); int num = number / 10; PostThread[] threads = new PostThread[1]; if(num > 0){ threads = new PostThread[10]; for(int i = 0; i <= 9; i++) { List<FaceBookUserQuitEntity> threadList = list.subList(i * num, (i + 1) * num > number ? number : (i + 1) * num); if (threadList == null || threadList.size() == 0) { new BusinessException("亚洲切分用户数据为空"); } threads[i] = new PostThread(HttpClientFactory.getInstance().getHttpAsyncClientPool().getAsyncHttpClient(), threadList, title, subTitle, imgUrl); } for (int k = 0; k< threads.length; k++) { threads[k].start(); logger.info("亚洲线程: {} 启动",k); } for (int j = 0; j < threads.length; j++) { try { threads[j].join(); } catch (InterruptedException e) { e.printStackTrace(); } } }else{ threads[0] = new PostThread(HttpClientFactory.getInstance().getHttpAsyncClientPool().getAsyncHttpClient(), list,title,subTitle, imgUrl); threads[0].start(); try { threads[0].join(); } catch (InterruptedException e) { e.printStackTrace(); } }
public PostThread(CloseableHttpAsyncClient httpClient, List<FaceBookUserQuitEntity> list, String title, String subTitle,String imgUrl){ this.httpClient = httpClient; this.list = list; this. title= title; this. subTitle= subTitle; this. imgUrl= imgUrl; } @Override public void run() { try { int size = list.size(); for (int k = 0; k < size; k += 100) { List<FaceBookUserQuitEntity> subList = new ArrayList<FaceBookUserQuitEntity>(); if (k + 100 < size) { subList = list.subList(k, k + 100); } else { subList = list.subList(k, size); } if(subList.size() > 0){ httpClient.start(); final long startTime = System.currentTimeMillis(); final CountDownLatch latch = new CountDownLatch(subList.size()); for (FaceBookUserQuitEntity faceBookEntity : subList) { String senderId = faceBookEntity.getSenderId(); String player_id = faceBookEntity.getPlayer_id(); logger.info("开始发送消息：playerid=" + player_id); String bodyStr = getPostbody(senderId, player_id, title, subTitle, imgUrl, "Play Game", ""); if (!bodyStr.isEmpty()) { final HttpPost httpPost = new HttpPost(URL); StringEntity stringEntity = new StringEntity(bodyStr, "utf-8"); stringEntity.setContentEncoding("UTF-8"); stringEntity.setContentType("application/json"); httpPost.setEntity(stringEntity); httpClient.execute(httpPost, new FutureCallback<HttpResponse>() { @Override public void completed(HttpResponse result) { latch.countDown(); int statusCode = result.getStatusLine().getStatusCode(); if(200 == statusCode){ logger.info("请求发消息成功="+bodyStr); try { logger.info(EntityUtils.toString(result.getEntity(), "UTF-8")); } catch (IOException e) { e.printStackTrace(); } }else{ logger.info("请求返回状态="+statusCode); logger.info("请求发消息失败="+bodyStr); try { logger.info(EntityUtils.toString(result.getEntity(), "UTF-8")); } catch (IOException e) { e.printStackTrace(); } } } @Override public void failed(Exception ex) { latch.countDown(); logger.info("请求发消息失败e="+ex); } @Override public void cancelled() { latch.countDown(); } }); } } try { latch.await(); } catch (InterruptedException e) { e.printStackTrace(); } long leftTime = 10000 - (System.currentTimeMillis() - startTime); if (leftTime > 0) { try { Thread.sleep(leftTime); } catch (InterruptedException e) { e.printStackTrace(); } } } } } catch (UnsupportedCharsetException e) { e.printStackTrace(); } }
以上工具代码可直接使用，发送逻辑代码需适当修改。
