Java 使用GSON错误解析JSON

我从服务器得到了这个Json响应

我已经创建了这个对象

public class EventDetails {

@SerializedName("id")
public String id;

@SerializedName("title")
public String name;

@SerializedName("price")
public String price;    

@SerializedName("bookingFee")
public String booking_fee;

@SerializedName("standby")
public int isStandBy;

@SerializedName("subTitle")
public String show;

@SerializedName("closeTime")
public String time;

@SerializedName("openTime")
public String date;

@SerializedName("date")
public String eventDate;

//@SerializedName("genre")
public String[] genre;

@SerializedName("venueId")
public String venue_id;

@SerializedName("overview")
public String overview;

@SerializedName("djs")
public String presenter;

@SerializedName("terms")
public String terms;

@SerializedName("firstCutOff")
public String firstCutOff;

@SerializedName("secondCutOff")
public String secondCutOff;

@SerializedName("autoCutOff")
public String thirdCutOff;

@SerializedName("tickets")
public String tickets;

//@SerializedName("images")
public String[] image_url;

//@SerializedName("codes")
public String[] promoCodes; 
 }

我正试图使用GSON来解析这段代码，就像我在其他项目中使用这段代码所做的那样

String result = httpRequest(params);
Type collectionType = new TypeToken<List<EventDetails>>(){}.getType();              
List<EventDetails> data = gson.fromJson(result, collectionType);

你有：

@SerializedName("terms")
public String terms;

您的JSON具有：

"terms": {
    "ID Criteria": [
        "Photo ID",
        "Over 21s"
    ],
    "Dress Code criteria": [
        ""
    ]
},

---

“术语”不是

字符串。它是一个对象（特别是一个包含两个字段的数组），Gson告诉您这一点
 为嵌套的对象创建Java对象，然后添加到EventDetails类中

例如代码
“代码”：[
{
“代码”：“HC0989”，
“价格”：“8.00”
}
]，

您可以创建一个类

public class Codes{
    public String code;
    public String price;
}

然后添加到事件详细信息中

public Codes[] codes;

我刚刚注释掉了serialize语句，但仍然得到相同的错误，类似的错误也适用于“codes”字段。您需要将这些声明为对象字段，其中对象属于具有适当字段的类；在“代码”的情况下，它需要是一个适当类的列表。是的，我注意到，在你第一篇文章之后，我现在只将id和venueId序列化，并注释了所有其他内容以查看它是否有效，但我仍然得到相同的错误。你的大部分
@SerializedName
注释都是多余的，实际上没有做任何事情；Gson与实际字段名匹配。使用该注释的唯一时间是JSON中的字段名与Java类中的字段名不同时。所以是的。。。如果Java中的某个字段在类型上仍然与您的JSON不匹配，那么您将不断收到错误，直到它匹配为止。更改名称以匹配我的JSON中的字段就成功了。为了他人的利益，请编辑您的答案以突出显示这一点。
public Codes[] codes;
