定義一個抽象類

package httpclientfactory;import org.testng.annotations.Test;/*** @Author: ws* @Description:* @Date: Created in 10:44 2018/11/2* @Modified By:*/ public abstract class AbstractHttpClient {/** @Description：這是關于httpclient的三種請求方式執(zhí)行的基本url方法** @param: [url]* @return: java.lang.String*/abstract String execute(String url);/** @Description:分別對Get，Post的請求傳參，Get沒有參數(shù)，Post含有參數(shù)** @param: [params]* @return: java.lang.Object*/abstract AbstractHttpClient setParams(Object params);}

工廠測試類
