復雜json的解析：jsonobject與jsonArray的使用

String parameter = {  
  success : 0,  
  errorMsg : "錯誤消息",  
  data : {  
   total : "總記錄數",  
   rows : [ {  
    id : "任務ID",  
    workName : "任務名稱",  
    assigneeName : "經辦人姓名",  
    name : "流程步驟名稱",  
    processInstanceInitiatorName : "發起人",  
    processInstanceStartTime : "發起時間",  
    createTime : "到達時間",  
    dueDate : "截止時間"  
   }, {  
    id : "ID",  
    workName : "名稱",  
    assigneeName : "經辦人",  
    name : "流程",  
    processInstanceInitiatorName : "發起人",  
    processInstanceStartTime : "發起",  
    createTime : "到達",  
    dueDate : "截止"  
   } ]  
  }  
 };  

    JSONObject jsonObject =JSONObject.fromObject(parameter);  

    System.out.println("success:"+jsonObject.get("success"));  
      System.out.println("errorMsg:"+jsonObject.get("errorMsg"));  

      System.err.println("total:"+jsonObject.getJSONObject("data").get("total"));  

      JSONObject data = jsonObject.getJSONObject("data");  
      JSONArray jsonArray = data.getJSONArray("row");  
      JSONObject row = null;  
      for (int i = 0; i < jsonArray.size(); i++) {  
       row = jsonArray.getJSONObject(i);  
       System.out.println("id:"+row.get("id"));  
       System.out.println("workName:"+row.get("workName"));  
       System.out.println("assigneeName:"+row.get("assigneeName"));  
       System.out.println("name:"+row.get("name"));  
       System.out.println("processInstanceInitiatorName:"+row.get("processInstanceInitiatorName"));  
       System.out.println("processInstanceStartTime:"+row.get("processInstanceStartTime"));  
       System.out.println("createTime:"+row.get("createTime"));  
       System.out.println("dueDate:"+row.get("dueDate"));  
      }
