【Java】从服务器上获取xml数据并写入本地
作者:许杰 / 发布于2013/10/11/ 414

	1.从服务上获取xml数据
	private List<VedioBean> getJsonXML() {
	 InputStream iStream = null;
	 String result = "";
	 try {
	 URL url = new URL("服务器的网址");
	 URLConnection connection = url.openConnection();
	 iStream = connection.getInputStream();
	 BufferedReader reader = new BufferedReader(new InputStreamReader(
	 iStream, "utf-8"));
	 StringBuffer sb = new StringBuffer();
	 String line = null;
	 while ((line = reader.readLine()) != null) {
	 sb.append(line + "\n");
	 }
	 iStream.close();
	 result = sb.toString();
	 } catch (Exception e) {
	 // TODO Auto-generated catch block
	 e.printStackTrace();
	 }
	 System.out.println("返回的数据" + result);
	 return parseJSON(result);
	 }
	2.解析获取到的数据
	private List<VedioBean> parseJSON(String str) {
	 ArrayList<VedioBean> jsonObjectList = new ArrayList<VedioBean>();
	 MovieDetail detail = null;
	 VedioBean vedioBean = null;
	 Param camshu = null;
	 ArrayList<Param> params = null;
	 ArrayList<MovieDetail> movieDetails = null;
	 JSONObject obj;
	 JSONArray json;
	 StringBuffer sb=null;
	
	 try {
	 obj = new JSONObject(str);
	 json = obj.getJSONArray("Qbox_data");
	 for (int i = 0; i < json.length(); i++) {
	 JSONObject object = json.getJSONObject(i);
	 vedioBean = new VedioBean();
	 System.out.println("类型:>>>>>>>>>>>>====="
	 + object.getString("type"));
	 vedioBean.setType(object.getString("type"));
	 System.out.println("type::>>>>>>>>" + object.getString("type"));
	 JSONArray jsonArray = object.getJSONArray("data");
	 sb=new StringBuffer();
	 sb.append("{"+"\"data\""+":"+"[");
	 for (int j = 0; j < jsonArray.length(); j++) {
	
	 JSONObject object2 = jsonArray.getJSONObject(j);
	 movieDetails = new ArrayList<MovieDetail>();
	 detail = new MovieDetail();
	 detail.setImg_url(object2.getString("img_url"));
	 sb.append("{"+"\"iconURL\""+":"+"\""+object2.getString("img_url")+"\"");
	 System.out.println("----->>>>>>img_url"
	 + object2.getString("img_url"));
	 detail.setImg_name(object2.getString("img_name"));
	 System.out.println("----->>>>>>img_name"
	 + object2.getString("img_name"));
	 sb.append(", "+"\"iconPOS\""+":"+"\""+object2.getString("position")+"\"");
	 detail.setPosition(object2.getString("position"));//位置
	 detail.setApk_name(object2.getString("apk_name"));
	 sb.append(", "+"\"content\""+":"+"\""+object2.getString("apk_name")+"\"");
	 System.out.println("----->>>>>>apk_name"
	 + object2.getString("apk_name"));
	 detail.setApk_action(object2.getString("apk_action"));
	 System.out.println("----->>>>>>apk_action"
	 + object2.getString("apk_action"));
	 detail.setApk_package(object2.getString("apk_package"));
	 System.out.println("----->>>>>>apk_package"
	 + object2.getString("apk_package"));
	 sb.append(", "+"\"class\""+":"+"\""+object2.getString("apk_class")+"\"");
	 detail.setApk_class(object2.getString("apk_class"));
	 System.out.println("----->>>>>>apk_class"
	 + object2.getString("apk_class"));
	 detail.setApk_type(object2.getString("apk_type"));
	 System.out.println("----->>>>>>apk_type"
	 + object2.getString("apk_type"));
	 JSONArray param = object2.getJSONArray("apk_request_data");
	 for (int k = 0; k < param.length(); k++) {
	 params = new ArrayList<Param>();
	 camshu = new Param();
	 System.out.println("----->>>>>>param1"
	 + param.getJSONObject(k).getString("param1"));
	 camshu.setParam1(param.getJSONObject(k).getString(
	 "param1"));
	 System.out.println("----->>>>>>param2"
	 + param.getJSONObject(k).getString("param2"));
	 camshu.setParam2(param.getJSONObject(k).getString(
	 "param2"));
	 System.out.println("----->>>>>>param3"
	 + param.getJSONObject(k).getString("param3"));
	 camshu.setParam3(param.getJSONObject(k).getString(
	 "param3"));
	 params.add(camshu);
	 }
	 detail.setParams(params);
	 movieDetails.add(detail);
	 System.out.println("参数的长度:>>>>>>>>>>" + param.length());
	 if((jsonArray.length()-1)==j){
	 sb.append("}");
	 }else{
	 sb.append("}"+",");
	 }
	
	 }
	 sb.append("]"+"}");
	 String path="/data/data/com.langyi.xiedemo/json/GetGameList.json";
	 String path2="/data/data/com.langyi.xiedemo/json/GetVodList.json";

	
	 if(object.getString("type").equals("电视直播")){
	 print(sb.toString(), new File(path));
	 }
	 if(object.getString("type").equals("网络影音")){
	 print(sb.toString(), new File(path2));
	 }
	 vedioBean.setData(movieDetails);
	 }
	 jsonObjectList.add(vedioBean);

	 } catch (JSONException e) {
	 e.printStackTrace();
	 }
	 System.out.println("movieDetails的长度:" + movieDetails.size());
	 System.out.println("jsonjsonObjectList的长度:" + jsonObjectList.size());
	 return jsonObjectList;
	 }
	3.将数据写入本地
	private void print(String str, File file) {
	 FileWriter fw = null;
	 BufferedWriter bw = null;
	 ;
	 try {
	 fw = new FileWriter(file, false);
	 bw = new BufferedWriter(fw);
	 bw.write(str + "\n");
	 bw.newLine();
	 bw.flush();
	 bw.close();
	 fw.close();

	 } catch (IOException e) {
	 // TODO Auto-generated catch block
	 e.printStackTrace();
	 try {
	 bw.close();
	 fw.close();
	 } catch (IOException e1) {
	 // TODO: handle exception
	 }
	 }
	 }
试试其它关键字
同语言下
可能有用的
