我这段时间一直用的Gson。还可以。反正封装类啊，MAP，集合什么的都方便。

其实可以不需要 map，直接一个类对象就可以转成 json，所有的 public 且以 get 开头的的方法，get 后面的关键字都会作为字段名被包装进去的。

哎~~~
查询出来结果是一个List<Noode>吧，举例子，纯手巧代码：
List<Noode> listNodes=数据库查询结果集；
int index=1;
Map<String,Noode> nodeMap=new HashMap<String,Noode>();
for(Noode node:listNodes){
nodeMap.put("demo_node_"+index,node);
}
System.out.print(JSONObject.toJSONString(nodeMap));//JSONObject对象是fastjson jar包里面的

//最外层实体
Node n = new Node();
//json中包含的json实体
User user = new User();
//json中嵌套的json
Map<String, Object> map1 = new HashMap<String, Object>();
map1.put("name", user.name);
map1.put("pwd", user.pwd);
//最外面的json
Map<String, Object> map = new HashMap<String, Object>();
map.put("id", n.id);
map.put("title", n.title);
//在json内封装一个json
map.put("user", map1);
//实用的JsonObject，包：json-lib 。
JSONObject json = JSONObject.fromObject(map);
推荐刚接触，可以去慕课网看一下json的视频，总体的了解一下。在实现方面推荐使用 JsonObject和Gson来解析或封装，
希望对你有所帮助

可以自己编写一个JSON转化类进行处理

使用fastjson或者类似的开源库，具体google json转对象。
