公司需求 做了相關測試 關於HttpClient解析url 獲取資料 和通過Solr API方式來獲取引數來做相關查詢 速度做相關對比

對比

1）httpClient的相應方法

 /**
     * Get方式發起請求
     *
     * @param url
     *            get請求的URL
     * @return
     */
    public static String requestByGetMethod(String url) {
        // 建立預設的httpClient例項
        CloseableHttpClient httpClient = getHttpClient();
        if (url.startsWith("https")) {
            try {
                httpClient = createSSLInsecureClient();
            }
            catch (GeneralSecurityException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        try {
            // 用get方法傳送http請求
            HttpGet get = new HttpGet(url);
            CloseableHttpResponse httpResponse = null;
            // 傳送get請求
            httpResponse = httpClient.execute(get);
            if(httpResponse.getStatusLine().getStatusCode() != 200){
                return "wrong";
            }
            try {
                // response實體
                HttpEntity entity = httpResponse.getEntity();
                if (null != entity) {
                    return EntityUtils.toString(entity, "UTF-8");
//                    return entity;
                }
            }
            finally {
                httpResponse.close();
            }
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        finally {
            try {
                closeHttpClient(httpClient);
            }
            catch (IOException e) {
                e.printStackTrace();
            }
        }
        return null;
    }

因為測試相對要小一下 高併發10000情況下 HttpClient訪問是247674ms，而且會報出N多錯誤

版本 Solr6.5.0 單機  資料規模大概1800W條資料

 通過Solr API查詢 結果是46938ms

HttpClient Solr

247674ms VS46938ms 結果很明顯 大概5倍的差距
