我有一個類層次結構，其基類名爲EntityModel，以及兩個類InvestorModel和AgentModel，它們都直接從它繼承並添加了一些屬性。然後，我創建Mule數據映射，將JSON映射到每個子類。Mule DataMapper IOException
的InvestorModel地圖工作正常，但AgentModel地圖失敗（在IDE預覽）與IOException說，它不能實例EntityModel。這看起來很奇怪，因爲它可以在InvestorModel地圖中實例化它。我發佈的錯誤，但我真的沒有任何來源發佈，因爲這些只是映射文件。我只是不知道從哪裏開始尋找。
騾Studio是最新的，並且V3.5.0
