应为BEGIN\u对象，但为BEGIN\u数组，用于使用GSON进行JSON分析

Question

预期BEGIN_OBJECT但BEGIN_ARRAY使用GSON解析JSON。我收到错误，这是由于Gson Json实现Json Format的类定义需要使用GSON解析而发生的

{
    "StatusCode": 4,
    "Data": {            
        "Data": [
                 [
                   {"Value": "19"},{"Value": "19"}],
                 [               
                   {"Value": "77"},{"Value": "4"}
                 ]
                ],

        "ColumnHeaders": [
            {
                "Width": "11.0%",
                "Title": "Date"
            },
            {
                "Width": "7.6%",
                "Title": "Total Clicks"
            }
        ],
        "ColumnHeaderGroups": [
            {
                "ColSpan": "1",
                "Title": ""
            },
            {
                "ColSpan": "7",
                "Title": "Chats"
            },
            {
                "ColSpan": "3",
                "Title": "Times (HH:MM:SS)"
            }
        ],

        "ReportHeaders": [
            {
                "Name": "Title",
                "Value": "Chat Summary By Date"
            },
            {
                "Name": "Run Date",
                "Value": "05/03/2016 10:52:39 AM"
            },
            {
                "Name": "Time Zone",
                "Value": "GMT+00:00"
            }
        ],
        "Summary": [              
            {
                "Value": "96"
            },
            {
                "Value": "23"
            }
        ]
    },
    "Status": "success"
}

用于使用gson进行分析的类：

static class Page {
        String Status;
        Data Data;
    }

    static class Data {
        String ReportID;
    }

    static class Page1 {
        String StatusCode;
        String Status;
        Data1 Data;
    }

    static class Data1 {

        List <Data2> Data;
        List<ColumnHeaders> ColumnHeaders;
        List<ReportHeaders> ReportHeaders;
        List<Summary> Summary;
    }

    static class Data2{
        List<object1> object1;
    }
    static class object1 {
        String  Value;
    }

    static class ColumnHeaders {
        String Title;
    }

    static class Summary {
        String  Value;
    }

    static class ReportHeaders {
        String  Value;
    }

使用gson解析json的代码：需要解析

"值"："19"，"值"："19"，"值"："77"，"值"："4"

内部数据数组[]。

  Gson gson = new Gson();
        Page1 page = gson.fromJson(json, Page1.class);
        String statusString = page.Status;
        System.out.println("Status : " + statusString);
        System.out.println("StatusCode : " + page.StatusCode);
        if ("success".equals(statusString)) {
            System.out.println("Inside if");
            for (ColumnHeaders item : page.Data.ColumnHeaders)
                System.out.print(item.Title + "     :");
            System.out.println();
            for (Summary item1 : page.Data.Summary)
                System.out.print(item1.Value + "    :");    
        }

Answer 1

试试把pojo换成这个

class Data{
    @SerializedName("Data")
    @Expose
    private List<List<Data2>> Data = new ArrayList<List<Data2>>();
    @SerializedName("ColumnHeaders")
    @Expose
    private List<ColumnHeader> ColumnHeaders = new ArrayList<ColumnHeader>();
    @SerializedName("ReportHeaders")
    @Expose
    private List<ReportHeader> ReportHeaders = new ArrayList<ReportHeader>();
    @SerializedName("Summary")
    @Expose
    private List<Summary> Summary = new ArrayList<Summary>();
    //getter setter
}

class Data2{
   @SerializedName("Value")
   @Expose
   private String Value;
   //getter setter
}
