java 字符串格式json java字符串转成json

private static Map map=new HashMap();
public static Map parserToMap(String s){
        JSONObject json=JSONObject.fromObject(s);
        Iterator keys=json.keys();
        while(keys.hasNext()){
            String key=(String) keys.next();
            String value=json.get(key).toString();
            if(value.startsWith("{")&&value.endsWith("}")){
                map.put(key, parserToMap(value));
            }else{
                map.put(key, value);
            }
        }
        return map;
    }

s是JSON格式的字符串，如下所示

{'name':'test','data':[{'data1':1}, {'data2':2}], 'test':{'test':'test'}}
