http client和http pool都是在局域网向一台tomcat发送

1:http client

public static String callPostJson(String url, String json) {
      HttpClient client = new HttpClient();     client.getParams().setContentCharset("utf-8");     client.getHttpConnectionManager().getParams().setSoTimeout(timeout);     PostMethod post = new PostMethod(url);     String result = StringUtils.EMPTY;     try {
          RequestEntity entity = new StringRequestEntity(json,"application/json","UTF-8");         post.setRequestEntity(entity);         post.setRequestHeader("Content-Type","application/json;charset=UTF-8");         client.executeMethod(post);         result = post.getResponseBodyAsString();     } catch (SocketTimeoutException se) {
          logger.error(se.getMessage(), se);         throw new ServiceException("connection.timeout");     } catch (Exception ex) {
          logger.error(ex.getMessage(), ex);         return "{\"success\":\"false\",\"msg\":\"" + ex.getMessage() + "\"}";     } finally {
          post.releaseConnection();     }     return result; }

测试结果；5000条耗时43秒 2：http pool client工厂

private static CloseableHttpClient httpClient; private static PoolingHttpClientConnectionManager cm; static {
      cm = new PoolingHttpClientConnectionManager();     cm.setMaxTotal(500);     cm.setDefaultMaxPerRoute(50);     final RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(10000).setConnectTimeout(1000).setConnectionRequestTimeout(500).build();     httpClient = HttpClients.custom().setConnectionManager(cm).setDefaultRequestConfig(requestConfig).build(); } public static CloseableHttpClient getHttpClient() {
      return httpClient; } http工具类

public static void callPostJson(String url, String param) {
      CloseableHttpClient httpClient = HttpPoolFactory.getHttpClient();     HttpPost post = new HttpPost(url);     try {
          StringEntity s = new StringEntity(param);         s.setContentEncoding("UTF-8");         s.setContentType("application/json");//发送json数据需要设置contentType         post.setEntity(s);         httpClient.execute(post);     } catch (Exception e) {
          logger.error(e.getMessage(), e);     } finally {
          post.releaseConnection();     } }
