关于JSON格式转为JavaBean？

Question

[

    {

        "url": "http://www.baidu.com",

        "title": "测试1",

        "type": 1,

        "pic": "null"

    },

    {

        "url": "http://www.baidu.com",

        "title": "测试2",

        "type": 2,

        "pic": "null"

    }

]

例如如上的JSON格式，其对应的JavaBean是什么样子的？

[]括号括起来的应该是对应List，但是其List并没有一个key，这该怎么弄？

Gson解析就报这里错了。。。

Answer 1

这是一个JOSN数组转List的问题，比如对象如下&nbsp;public class TestBean{&nbsp; &nbsp; &nbsp;private String url;&nbsp; &nbsp; &nbsp;private String title;&nbsp; &nbsp; &nbsp;private String type;&nbsp; &nbsp; &nbsp;private String pic;&nbsp; &nbsp; &nbsp;//省略getter,setter}你给的json字符串转换成list应该是：List<TestBean> list = gson.fromJson(str, new TypeToken<List<TestBean>>(){}.getType());

Answer 2

public class Test{&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; private List<TestBean> tests;&nbsp; &nbsp; //省略getter,setter&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; public static class TestBean{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;private String url;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;private String title;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;private String type;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;private String pic;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;//省略getter,setter&nbsp; &nbsp; }}//这就能得到如题所示的json了JSON.toJSON(Test.getTests())

Answer 3

在json中，[]表示数组，{}表示对象，上面的结构，数组中有两个对象，每个对象有四个属性。数据结构为List<Object>&nbsp;list&nbsp;=&nbsp;new&nbsp;ArrayList<Object>();
