java中string类型字符串转换成map，方便取值

String array_str = "{\"24\":\"公务员补收\",\"25\":\"特殊手工补收\",\"10\":\"正常应缴\",\"32\":\"一次性清算\",\"20\":\"补收\",\"21\":\"离休人员补收\"}";

方法一：

        Gson gson = new Gson();
        Map map = new HashMap();
        map = gson.fromJson(array_str, map.getClass());
        String name = (String) map.get("10");
        System.out.println("缴费类型为:"+name);

方法二：

        Gson gson = new Gson();
        Map hashMap = new HashMap();
        hashMap = gson.fromJson(array_str, new TypeToken>() {
        }.getType());
        String name = (String) hashMap.get("10");
        System.out.println(name);

方法三：

com.alibaba.fastjson

String responseEntityBody = responseEntity.getBody();//{"msg":"操作成功！","obj":{"uid":"0400022700000063-1"},"success":true}
JSONObject parseObject = JSONArray.parseObject(responseEntityBody);
JSONObject obj = parseObject.getJSONObject("obj");
String uid = obj.getString("uid");
