jsonArrays数组获取里面数据方法小记

原始数据：

[EngineWorkerThread-1-MethodExecutor-1] INFO com.jd.forcebot.engine.TestUtils - [{"name":"th","img":"//img.jd.co.th/thact/s200x200_jfs/t4/118/14548049/15023/2286ba0/5b603facN7de7db13.jpg","fromPrice":"10000.00","toPrice":"0.00","count":371,"actId":"951","skuId":"2092314","soldOut":true,"launched":true},{"name":"th","img":"//img.jd.co.th/thact/s200x200_jfs/t4/118/14548049/15023/2286ba0/5b603facN7de7db13.jpg","fromPrice":"10000.00","toPrice":"0.00","count":371,"actId":"952","skuId":"2092314","soldOut":true,"launched":true}]

获取里面某个字段的方法：

String a = "原始数据"； 

     JSONArray jsonArray = JSON.parseArray(a);

        for(Object o : jsonArray){
            JSONObject jsonObject = (JSONObject) o;
//            System.out.println(jsonObject.toJSONString());
            System.out.println(jsonObject.get("actId"));

        }
    }

结果
