     以下测试以上面这段JSON作为参考进行测试。

第三方JAR包：（阿里巴巴）fastjson-1.2.5.jar      （谷歌）gson-2.2.4.jar

            for (int n = 0; n < 100000; n++) {
                // 使用JSON 操作 工具将JSON字符串封装到实体类
                TestBean1 toBean = my_gson.fromJson(my_json, my_type);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

public class TestBean1 {
    public String testStr;
    public Integer testInt;

    public List<NewsItem> data;
    public List<Integer> extend;
    public int retcode;

    public class NewsItem {
        public List<NewsCategory> children;
        public int id;

}

运行结果：
