無法解析名稱錯誤的視圖Spring MVC 4 + Apache Tiles 3

Question

嘗試將apache tile 3與Spring MVC 4集成時出現錯誤。請在這種情況下幫助我。 想法是創建使用Apache Tiles動態更新的頁面。 我檢查了依賴關系，它們看起來都很好。 我認為我的配置丟失了某些內容，或者控制器無法識別圖塊配置文件。

請幫我解決一下這個。 我是開發Spring MVC和Apache Tiles應用程序的新手。 請提出該代碼可能出了什么問題。

您已指定為，但未定義base-definiation（它是app-default）。它應該擴展app-default或app-default都應更改為app-base
