http性能测试

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();
    }
}
