来自同名json的Java类

我有一个JSON对象，如下所示：

...
    {
       "url": "checkout.bodenusa.com/en-US"
    },
    {
       "url": [
            ".bonton.com/checkout/",
            ".bonton.com/CheckoutView"
        ]
    }
...

对于响应服务器，我的Java类应该是什么样子

我尝试了这个片段，但它不正确：

@SerializedName("url")
@Expose
private List<String> urlList = null;
@SerializedName("url")
@Expose
private String url;

@SerializedName（“url”）
@暴露
私有列表urlList=null；
@序列化名称（“url”）
@暴露
私有字符串url；

使用此选项生成POJO的

创建一个类似

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

import java.util.List;

public class Model {

这是无效的json:

{“1”}，{“2”}

您的数据是无效的json变量将URL对象修改如下：

“URL”：[“1”，“2”]

@n00dl3我不只是示例，我还以为您自以为是。我更正了我的示例。这是一个糟糕的设计，我的意思是在json中从

String

切换到

String[]

听起来是个糟糕的主意。我想，你需要实现某种类型的。但是如果您有选择的话，我建议您只使用字符串[]。请仔细考虑。我得到了数组。继续使用我提供的链接尝试json。一个问题。我有日期反序列化.setDateFormat（“MM/dd/yyyy”）。现在我遇到了错误com.google.gson.JsonSyntaxException:4/10/2017，我如何在ArrayAdapter或ArrayAdapterFactory中传输反序列化到目前为止？
