改造GSON StackoverflowError

Question

我正在將Retrofit與Gson一起用於發出HTTP請求。 但是在請求之后，我得到以下錯誤。 有人可以幫我解決這個問題嗎？

EventsData.java

public class EventsData

    public EventsData()

    public List<EventsData> getResults() {
        return results;

    public void setResults(List<EventsData> results) {
        this.results = results;
    }
}

Answer 1

您的EventsData類僅包含List<EventsData> ，這似乎是遞歸地獄的秘訣。 也許這是一個錯誤？
