今天项目中用到的json解析

需要解析的json数据：

String json = "{code:0,message:Copy library add success,number:10,id:0001}";

将解析的数据放入dbinfo对象中。

解析方法：

public static dbinfo copyLibResultConvertObject(String json) {
        dbinfo info = new dbinfo();
        JSONObject jo = JSON.parseObject(json);
        System.out.println(jo);
        info.setId(Integer.parseInt(jo.get("code").toString()));
        info.setCbkname(jo.get("id").toString());
        info.setCount(Integer.parseInt(jo.get("number").toString()));
        info.setQuery(jo.get("message").toString());
        return info;
    }

 

需要解析的json数据：

String json = "{\"code\":\"0\",\"message\":\"success\",\"id\":\"0000001\",\"relatives\":[{\"image_name0\":[{\"path\":\"XX1\",\"score\":\"111\"},{\"path\":\"XX2\",\"score\":\"222\"},{\"path\":\"XX3\",\"score\":\"223\"}] }, {\"image_name1\":[{\"path\":\"YY1\",\"score\":\"11\"},{\"path\":\"YY2\",\"score\":\"12\"},{\"path\":\"YY3\",\"score\":\"13\"}]}]}";

由于relatives对象中的image_name是一个有规律的key值，获取方法如下：

public static List<dbinfo> ChackImgCopyOrFaceDiscernResultConvertList(
            String json) {
        List<dbinfo> listInfo = new ArrayList<dbinfo>();
        JSONObject jo = JSON.parseObject(json);
        JSONArray ja = JSONArray.parseArray(jo.getString("relatives")
                .toString());
        int i = 0;
        for (Iterator iterator = ja.iterator(); iterator.hasNext();) {
            JSONObject obj = (JSONObject) iterator.next();
            JSONArray ji = JSONArray.parseArray(obj.getString("image_name" + i)
                    .toString());
            for (Iterator iterator2 = ji.iterator(); iterator2.hasNext();) {
                JSONObject obj2 = (JSONObject) iterator2.next();
                dbinfo info = new dbinfo();
                info.setPicturepath(obj2.get("path").toString());
                info.setCbkname(obj2.get("score").toString());
                listInfo.add(info);
            }
            i++;
        }
        return listInfo;
    }

 

需要解析的json数据如下：

String json = "{code:0,message:\"success\",faceDatabase:[{name:\"XXf\"},{name:\"YYf\"}],\"objDatabase\":[{name:\"XXo\"},{name:\"YYo\"}]}";

解析方法：

public static List<Map<String, String>> viewCopyLibIdList(String json) {
        List<Map<String, String>> listMap = new ArrayList<Map<String, String>>();
        JSONObject jo = JSON.parseObject(json);
        System.out.println(jo);
        //人脸识别库
        JSONArray fd = JSONArray
                .parseArray(jo.getString("faceDatabase").toString());
        for (Iterator iterator = fd.iterator(); iterator.hasNext();) {
            Map<String, String> fmap = new HashMap<String, String>();
            JSONObject obj = (JSONObject) iterator.next();
            fmap.put("name", obj.get("name").toString());
            listMap.add(fmap);
        }
        //拷贝检测库
        JSONArray od = JSONArray
                .parseArray(jo.getString("objDatabase").toString());
        for (Iterator iterator = od.iterator(); iterator.hasNext();) {
            Map<String, String> omap = new HashMap<String, String>();
            JSONObject obj = (JSONObject) iterator.next();
            omap.put("name", obj.get("name").toString());
            listMap.add(omap);
        }
        return listMap;
    }

代码亲测好使。
