将Json映射到POJO

Question

{
    "Filters": [{
        "Decription": "Default",
        "FieldSelected": {
            "AppointmentDate": true,
            "AppointmentDateOrder": 1            
            "ptStatusOrder": 3
        },
        "FilterID": 1
    }, {
        "Decription": "chart",
        "FieldSelected": {
            "AppointmentDate": true,
            "AppointmentDateOrder": 1,           
            "ptStatusOrder": 0
        },
        "FilterID": 2
    }]
}

I am getting a response of this structure, how do i map it to my POJO class. Can anyone give a sample POJO class for this json structure. I am using Gson for Request and Response.

Answer 1

Just map one Json Object as a Java Class. And make an Array of Object as a List..

Like, (pseudo code only)

You are using GSON library so import SerializedName in your pojo classes.

import com.google.gson.annotations.SerializedName;

Pojo Class looks like,

public class Filter {

    @SerializedName("Decription") // This requires same as your Json key 
    public String description;
    @SerializedName("FieldSelected") // The Json Object of FieldSelected
    public Field listDetails;

}

public class Field {
    @SerializedName("ptStatusOrder")
    public int status;
    @SerializedName("AppointmentDateOrder")
    public int dateOrder;
    @SerializedName("AppointmentDate")
    public boolean appDate;
}

And main ListFileter class,

public class ListFilter {

        @SerializedName("Filters") 
        public List<Filter> listFilter;

    }

And in Android code,

Gson gson = new Gson();
ListFilter listFilter = gson.fromJson(jsonResponse, ListFilter.class);
