     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

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

 }

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

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

}

运行结果：
