我想返回一個ArrayList的chatbox類對象，其中有一個字段allowedUser是另一個類對象User的ArrayList。然而每當我嘗試返回一個值，它只會返回其他字段。java返回數組列表的一個對象的數組列表另一個對象的其餘對象
我附上了模型類和服務的代碼。你們能幫我找出解決這個問題的最佳方法嗎？提前致謝。

你能成爲一個更具體一點？你剛剛傾倒的代碼量巨大這裏究竟哪裏是你有問題嗎？哪種方法/類/線？ –
當然，我有chatbox類，其中有字段allowedUser這是用戶類對象的arraylist ..這裏的問題是在休息XML數據我有除用戶arraylist的所有其他字段，你可以看到..我希望你現在得到它.. –
你還可以添加'User'類嗎？這對你的問題來說很重要，但它缺失。 –
