字串轉為json物件並獲取其中屬性

String addrJson = GnthkUtil.geturl1();
JSONObject jobjectaddr =  JSON.parseObject(addrJson);
            String addr=jobjectaddr.getJSONObject("result").getString("formatted_address");

如果獲得的jsonobject的裡面是陣列

則:

@RequestMapping("/toProduct")
    public String toProduct() {
        try {
            String addrJson = GnthkUtil.geturl("http://xxxxxxxxx", "");

            JSONObject jsonObject =  JSON.parseObject(addrJson);
            JSONArray array = jsonObject.getJSONArray("result");
            String string = jsonObject.getJSONArray("result").toJSONString();


            for(int i=0;i<array.size();i++){
                JSONObject job = array.getJSONObject(i); // 遍歷 jsonarray 陣列，把每一個物件轉成 json 物件
                System.out.println(job.get("pdtname"));

            }


        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return null;
    }
