复杂json的解析：jsonobject与jsonArray的使用

String parameter = {
  success : 0,
  errorMsg : "错误消息",
  data : {
   total : "总记录数",
   rows : [ {
    id : "任务ID",
    workName : "任务名称",
    assigneeName : "经办人姓名",
    name : "流程步骤名称",
    processInstanceInitiatorName : "发起人",
    processInstanceStartTime : "发起时间",
    createTime : "到达时间",
    dueDate : "截止时间"
   }, {
    id : "ID",
    workName : "名称",
    assigneeName : "经办人",
    name : "流程",
    processInstanceInitiatorName : "发起人",
    processInstanceStartTime : "发起",
    createTime : "到达",
    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"));
      }
