json這里選用了fast-json

先看服務端代碼如下

package?novelserver.servlet;import?java.io.IOException; import?java.io.PrintWriter; import?java.util.List;import?javax.servlet.ServletException; import?javax.servlet.annotation.WebServlet; import?javax.servlet.http.HttpServlet; import?javax.servlet.http.HttpServletRequest; import?javax.servlet.http.HttpServletResponse;import?model.Novel; import?spider.BiqugeNovelPageProcesser; import?spider.BiqugeNovelPipeline; import?spider.NovelList; import?us.codecraft.webmagic.Spider;import?com.alibaba.fastjson.JSON; /***?首頁推薦*?@author?liangzhenghui**/ @WebServlet(urlPatterns={"/homeRecommend"}) public?class?HomeRecommend?extends?HttpServlet?{private?static?final?long?serialVersionUID?=?430306605309121990L;@Overrideprotected?void?doGet(HttpServletRequest?req,?HttpServletResponse?resp)throws?ServletException,?IOException?{doPost(req,?resp);}@Overrideprotected?void?doPost(HttpServletRequest?req,?HttpServletResponse?resp)throws?ServletException,?IOException?{//筆趣閣String?url?=?"http://www.biquge.com/";Spider.create(new?BiqugeNovelPageProcesser()).addUrl(url).addPipeline(new?BiqugeNovelPipeline()).run();List<Novel>?novelList?=?NovelList.getNovelList();//解決中文亂碼問題resp.setContentType("text/html;charset=UTF-8");??//目的是為了控制瀏覽器的行為，即控制瀏覽器用UTF-8進行解碼；//的目的是用于response.getWriter()輸出的字符流的亂碼問題，如果是response.getOutputStream()是不需要此種解決方案的；因為這句話的意思是為了將response對象中的數據以UTF-8編碼后發向瀏覽器；resp.setCharacterEncoding("UTF-8");?PrintWriter?out?=?resp.getWriter();out.write(JSON.toJSONString(novelList));} }

android客戶端向服務端發起請求以及接收返回數據代碼如下

public?static?List<Novel>?getHotNovelList()?{List<Novel>?novelList?=?new?ArrayList<Novel>();String?url?=?"http://192.168.1.104:8080/novel/homeRecommend";DefaultHttpClient?httpclient?=?new?DefaultHttpClient();HttpGet?httpGet?=?new?HttpGet(url);try?{HttpResponse?response?=?httpclient.execute(httpGet);novelList?=?JSON.parseArray(EntityUtils.toString(response.getEntity()),?Novel.class);}?catch?(ClientProtocolException?e)?{e.printStackTrace();}?catch?(IOException?e)?{e.printStackTrace();}return?novelList;}
