用多个同名类型处理JSON响应

Question

{
    "success": false,
    "errorMessages": [
        "You have to select a maximum load of <span style='color:red;'>0</span> Credit/Course but you have selected <span style='color:red;'>3</span> Credit/Course --- [R060]",
        "You can register courses as a full study with a load limit between <span style='color:red;'>12</span> and <span style='color:red;'>18</span> Credit/Course, but you have selected <span style='color:red;'>9</span> Credit/Course --- [R062]"
    ],
    "isConflict": 0
}

{
    "ignoreConflictValue": "W",
    "isConflict": 1,
    "conflict": [
        {
            "EXAM_DATE": "01/01/2019",
            "START_TIME": "08:00 AM",
            "END_TIME": "09:30 AM",
            "COURSE_NAME_SL": "مقاومة مواد,تقنيات الحفر البحري",
            "COURSE_NAME_PL": "STRENGTH OF MATERIALS,OFFSHORE TECHNOLOGY",
            "COURSES_COUNT": "2",
            "ACTIVE": "A"

null

我的问题是如何为这种情况定义POJO类。

我试图用@nullable创建两个同名字段，但是GSON抱怨POJO有重复的字段。

Answer 1

在Kotlin中，您可以执行以下操作：

用如下所示的泛型定义“ApiResponse”类：

class ApiResponse(@SerializedName("success") val success : Any,
                  @SerializedName("errorMessages") val errorMessages : Array<Any>,
                  @SerializedName("isConflict")
                  val isConflict : Integer)

然后，在您的活动中，使用Gson将响应转换为

 var responseOne = Gson().fromJson(textConflictOneResponse, ApiResponse::class.java)
        var responseZero = Gson().fromJson(textConflictZeroResponse, ApiResponse::class.java)

if (responseOne.success is Boolean){
            Log.v(TAG,"Boolean")
        } else{
            Log.v(TAG,"not boolean")
        }
