Retrofit 泛型解析遇到com.google.gson.i

在使用Retrofit进行网络请求时出现了以下异常：

java.lang.ClassCastException: com.google.gson.internal.LinkedTreeMap cannot be cast to com.fr.konwledge.bean.TestBean

泛型解析错误。最初我的JavaBean类的写法如下：

public class TodayListBean {
    
    private boolean isError;
    private ResultsBean results;
    private List<String> category;

    public boolean isError() {
        return isError;
    }

    public ResultsBean getResults() {
        return results;
    }

    public List<String> getCategory() {
        return category;
    }

    public static class ResultsBean<T> {
        private List<T> Android;
        private List<T> App;
        private List<T> iOS;

        public List<T> getAndroid() {
            return Android;
        }

        public void setAndroid(List<T> android) {
            Android = android;
        }

        public List<T> getApp() {
            return App;
        }

        public void setApp(List<T> app) {
            App = app;
        }

        public List<T> getiOS() {
            return iOS;
        }

        public void setiOS(List<T> iOS) {
            this.iOS = iOS;
        }


    }
}

后改成如下，解决了问题。

public class TodayListBean<T> {
    
    private boolean isError;
    private ResultsBean<T> results;
    private List<String> category;

    public boolean isError() {
        return isError;
    }

    public ResultsBean<T> getResults() {
        return results;
    }

    public List<String> getCategory() {
        return category;
    }

    public static class ResultsBean<T> {
        private List<T> Android;
        private List<T> App;
        private List<T> iOS;

        public List<T> getAndroid() {
            return Android;
        }

        public void setAndroid(List<T> android) {
            Android = android;
        }

        public List<T> getApp() {
            return App;
        }

        public void setApp(List<T> app) {
            App = app;
        }

        public List<T> getiOS() {
            return iOS;
        }

        public void setiOS(List<T> iOS) {
            this.iOS = iOS;
        }

    }
}
