我试图解析这个json
{"status":"ok","results":{"query":{"id":"6081","name":"UB1656-Palazzo Versace Resort in Culture Village","query":"Aswathy VS : <\/strong>
Test Query","add_date":"2014-08-05 08:27:45"},"replies":[{"replied_by":"Ventures Onsite","replied_on":"05-Aug-2014 09:05:19 AM","reply":"We have received your Test Query."},{"replied_by":"Me","replied_on":"05-Aug-2014 01:28:00 PM","reply":"Thanks... "}]}}
我的Pojo课堂
import java.util.ArrayList;
public class QueryRepliesList {
public String status;
public ArrayList<Result> results;
public class Replies {
public String id;
public String name;
public String query;
public String add_date;
public String replied_by;
public String replied_on;
public String reply;
}
public class Result {
public ArrayList<Replies> query;
public ArrayList<Replies> replies;
}
}
我想通过这个来称呼它
QueryRepliesList queryReply = gson.fromJson(reader,
QueryRepliesList.class);
但是我有以下异常
引起原因：com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期为字符串，但为BEGIN_OBJECT
我尝试通过改变
根据类似问题的答案建议几次进行Pojo课，但是没有任何效果，请一些帮助。提前感谢
根据JSON您提供的信息，我看不到如何获取所提供的错误，相反，您会看到
预期为BEGIN_ARRAY，但为BEGIN_OBJECT
因为results和query都是JSON_OBJECT。为了说明这一点，我将所有内容都放入了junit测试中。
@org.junit.Test
public void asPosted() {
final String json = "{'status':'ok','results':{'query':{'id':'6081','name':'UB1656-Palazzo Versace Resort in Culture Village','query':'Aswathy VS : <\\/strong>\n"
+ "Test Query','add_date':'2014-08-05 08:27:45'},'replies':[{'replied_by':'Ventures Onsite','replied_on':'05-Aug-2014 09:05:19 AM','reply':'We have received your Test Query.'},{'replied_by':'Me','replied_on':'05-Aug-2014 01:28:00 PM','reply':'Thanks... '}]}}";
QueryRepliesContainer data = new Gson().fromJson(json, QueryRepliesContainer.class);
Assert.assertEquals("ok", data.getStatus());
Assert.assertEquals(2, data.getRepliesCount());
Assert.assertEquals("6081", data.getQueryId());
}
通常，您将为每个创建一个POJOJSON_OBJECT。例外情况包括提供自定义解串器。根据需要公开“内部”数据的程度，您将需要迁移内部类以进行公共级别的公开。我将它们分别嵌套在JSON结构上。因此，根据所提供的内容，您将需要与以下内容类似的内容：
class QueryRepliesContainer {
private String status;
private Result results;
public String getStatus() {
return status;
}
public int getRepliesCount() {
return results.replies.size();
}
public String getQueryId() {
return results.query.id;
}
private class Result {
private Query query;
private List<Replies> replies;
private class Query {
private String id;
private String name;
private String query;
}
private class Replies {
private String add_date;
private String replied_by;
private String replied_on;
private String reply;
}
}
}
