json取值

数据库格式：
[{"jjxId":13,"jjxName":"测试三","jjxDate":"1111"},{"jjxId":15,"jjxName":"测试五","jjxDate":"2222"}]

		List<String> lst = new ArrayList<>();

		JSONArray pmNameArr = JSON.parseArray(djbPo.getJjxXq());;
		for (Object x : pmNameArr) {
			JSONObject info = JSON.parseObject(x.toString());
			lst.add(info.get("jjxId").toString());
		}

		BBB jiangjinFpJjlydjb = new BBB();
