一段JSON，如何进行解析10

从sFlow-rt提供的REST API得到了一段JSON数据，如何进行解析呢？
{
"17.ifInmulticastpkts": 0,
"17.ifindex": "17",
"17.ifindiscards": 0,
"17.ifinerrors": 0,
"17.ifinoctets": 0,
"17.ifinucastpkts": 0,
"17.ifoutdiscards": 0,
"17.ifouterrors": 0,
"17.ifoutoctets": 0,
"17.ifoutucastpkts": 0,
"17.ifspeed": 10000000000,
"17.iftype": "ethernetCsmacd",
"19.ifInmulticastpkts": 0,
"19.ifindex": "19",
"19.ifindiscards": 0,
"19.ifinerrors": 0,
"19.ifinoctets": 0,
"19.ifinucastpkts": 0,
"19.ifoutdiscards": 0,
"19.ifouterrors": 0,
"19.ifoutoctets": 0,
"19.ifoutucastpkts": 0,
"19.ifspeed": 10000000000,
"19.iftype": "ethernetCsmacd",
"21.ifInmulticastpkts": 0,
"21.ifindex": "21",
"21.ifindiscards": 0,
"21.ifinerrors": 0,
"21.ifinoctets": 0,
"21.ifinucastpkts": 0,
"21.ifoutdiscards": 0,
"21.ifouterrors": 0,
"21.ifoutoctets": 0,
"21.ifoutucastpkts": 0,
"21.ifspeed": 10000000000,
"21.iftype": "ethernetCsmacd",
"23.ifInmulticastpkts": 0,
"23.ifindex": "23",
"23.ifindiscards": 0,
"23.ifinerrors": 0,
"23.ifinoctets": 0,
"23.ifinucastpkts": 0,
"23.ifoutdiscards": 0,
"23.ifouterrors": 0,
"23.ifoutoctets": 0,
"23.ifoutucastpkts": 0,
"23.ifspeed": 10000000000,
"23.iftype": "ethernetCsmacd"
}
也就是每组数字对应的一个model，但是没有在JSON中分开，这样的JSON如何进行解析，谢谢各位大神。

public class JSon2ModelTest {
	public static void main(String[] args) {
		Map<String,String> map = new HashMap<String,String>();
		map.put("1.xx", "1xx");
		map.put("1.yy", "1yy");
		map.put("1.zz", "1zz");
		map.put("2.xx", "2xx");
		map.put("2.yy", "2yy");
		map.put("2.zz", "2zz");
		map.put("3.xx", "3xx");
		map.put("3.yy", "3yy");
		map.put("3.zz", "3zz");
		String str=JSON.toJSON(map).toString();
		Map<String,String> m=JSON.parseObject(str, Map.class);
		Set<String> s=m.keySet();
		Iterator<String> it=s.iterator();
		//缓存分组后的数据的map对象
		Map<String,List<String>> mm=new HashMap<String,List<String>>();
		//缓存分组后的数据的map对象的key
		List<String> listKey=new ArrayList<String>();
		
		//初始化缓存的map对象开始
		List<String> listInit=new ArrayList<String>();
		String t = it.next(); 
		String initKey = t.substring(0,t.indexOf("."));
		listKey.add(initKey);
		listInit.add(t);
		mm.put(initKey, listInit);
		//初始化缓存的map对象结束
		for(;it.hasNext();){
			String str2 = it.next();
			String temp = str2.substring(0,str2.indexOf("."));
			if(mm.containsKey(temp)){
				mm.get(temp).add(str2);
			}else{
				List<String> ll = new ArrayList<String>();
				listKey.add(temp);
				mm.put(temp, ll);
			}
		}
	}
}

这是测试的代码，你可以参考一下
