java中返回的JSON对象转换成List 用法

java中返回的JSON对象转换成List 用法

解析用法：

//调用URL --分页
String str = CommonConstant.getPhotoAlbumByUserIdURL() + userid  + "&pageNo="
       + paginationDto.getPageNum() + "&pageSize=" + paginationDto.getRowsPerPage();
       
       HttpClient client = new HttpClient();
       PostMethod method = new PostMethod(str);
       List<PhotoAlbumVO>  photoAlbumList = new ArrayList<PhotoAlbumVO>();
       try {
            client.executeMethod(method);
       } catch (HttpException e) {
            e.printStackTrace();
       } catch (IOException e) {
            e.printStackTrace();
       }
       String returnJson = "";
       try {
            returnJson = method.getResponseBodyAsString();//返回json字符串值
            System.out.println("---------------------returnJson---------------------------------" + returnJson);
            if(returnJson != null && returnJson != ""){
            String strJson = returnJson.replace("?(", "").replace(")", "").replace(";", "");
            if(strJson.startsWith("{")){
                JSONObject jsonObject = JSONObject.fromObject(strJson);
                String code = jsonObject.getString("code").toString();
                if("200".equals(code)){
                    JSONArray jsonArray = JSONArray.fromObject(jsonObject.get("result"));
                    JSONObject jsonObj = jsonArray.getJSONObject(0);
                    JSONArray dataArray = JSONArray.fromObject(jsonObj.get("data"));
                   
                    for (int i = 0, len = dataArray.size(); i < len; i++) {
                        PhotoAlbumVO vo = new PhotoAlbumVO();
                        JSONObject jsonVideo = dataArray.getJSONObject(i);
                        vo.setId(jsonVideo.get("id").toString());
                        vo.setUserid(jsonVideo.get("userid").toString());
                        vo.setTitle(jsonVideo.get("title").toString());
                        vo.setIntro(jsonVideo.get("intro").toString());
                        vo.setCoverPath(jsonVideo.get("cover_path").toString());
                        vo.setType(Integer.parseInt(jsonVideo.get("type").toString()));
                        vo.setNumberPhoto(Integer.parseInt(jsonVideo.get("number_photo").toString()));
                        vo.setCreatedTime(DateTimeUtils.parseFullDateTime(DateUtil.getDateTimeByMillisecond(jsonVideo.get("created_time").toString())));
                        vo.setUpdatedTime(DateTimeUtils.parseFullDateTime(DateUtil.getDateTimeByMillisecond(jsonVideo.get("updated_time").toString())));
                        
                        photoAlbumList.add(vo);
                    }
                    JSONArray pageArray = JSONArray.fromObject(jsonObj.get("page"));
                    JSONObject pagerObj = pageArray.getJSONObject(0);
                    JSONArray pagerArray = JSONArray.fromObject(pagerObj.get("pager"));
                    JSONObject pagerObj1 = pagerArray.getJSONObject(0);
                    paginationDto.setTotalRowNum(Long.valueOf(pagerObj1.get("pageSum").toString()));
                    
                }
                }
             }
           } catch (IOException e1) {
                e1.printStackTrace();
           }finally{
            //使用完成后要释放链接
            method.releaseConnection();
           }
           System.out.println("===========================================size"+photoAlbumList.size());
           return photoAlbumList;

返回json字符串值代码如下：
