Android gson中的java.lang.StackOverflower错误

在以MVP结构构建我的应用程序的过程中，我遇到了一个问题，那就是当我调用web服务以响应成功后的改进 我将整个数据传递到json字符串中，因此它会促使我这样做

我的原木猫：

以下是我的改装API调用：

//API Call for Pitch
public void pitch() {
    services
        .getAPI()
        .pitchList()
        .enqueue(new Callback<PitchList_Res>() {
            @Override
            public void onResponse(Call<PitchList_Res> call, Response<PitchList_Res> response) {
                if (!response.body().getdATA().isEmpty()) {
                    Gson gson1=new Gson();
                    String json = gson1.toJson(response);
                    mListener.pitch(json);
                }
            }

            @Override
            public void onFailure(Call<PitchList_Res> call, Throwable t) {
                call.cancel();
                Toast.makeText(context, R.string.error, Toast.LENGTH_SHORT).show();
            }
        });
}

这是我的两个模型课：（PitchList\u Res）

我也遇到了同样的问题&发现错误是由于 对象类型的类中的变量

我正在解析一个java类对象，该对象包含内部对象，其中一些包含object类型的变量。因此，Gson库无法解析该数据

我已经删除了变量的对象类型声明，问题得到了解决

我认为Gson库无法将java对象解析为json，如果 java对象包含一些泛型类型的变量（如对象 在我的案例中输入）

哪一行出现崩溃或异常，比如给我一段代码进行分析。当我调试我的应用程序时，我在改装呼叫中遇到崩溃。Gson gson1=新的Gson（）；字符串json=gson1.toJson（响应）；

//Response of Pitch
@Override
public void pitch(String response_pitch) {

    editor.putString(Preference_Data.PITCH_RESPONSE, response_pitch);

        final TextView tvtitle = (TextView) pitchview

        String id = pitchlist.get(i).getpITCHTYPEID().toString();
        tvtitle.setId(Integer.valueOf(id));

        tvtitle.setText(pitchlist.get(0).getpITCHSHORT().toString());
