json 打包和解析数据

Json 解析List<Domain> dataList：

domain 类设置

public class XxtsAllDomain  extends BaseDomain {
 private List<XxtsDomain> dataList;
｝

public class XxtsDomain  extends BaseDomain {
	//default serial version id, required for serializable classes.
	private static final long serialVersionUID = 1L;
	private String userId;			//用户ID
	private String sbsbm;			//设备识别码
	private int messCount;			//消息条数   
}

 封装代码：

XxtsAllDomain xxtsAllProc = dao.executeTsProc();
List<XxtsDomain> dataList = xxtsAllProc.getDataList();
if(dataList == null || dataList.isEmpty()){
	System.out.println("no data");
	return;
}
XxtsAllDomain xxtsAll = new XxtsAllDomain();
xxtsAll.setDataList(dataList);
JSONObject obj = JSONObject.fromObject(xxtsAll);  

 解析：

JSONObject jsonObject = JSONObject.fromObject(sb.toString());
JSONArray array = jsonObject.getJSONArray("dataList");
dataList = JSONArray.toList(array, new XxtsDomain(), new JsonConfig());
