Vue element admin Table 替換 資料(三)

Java object to json 小轉換

https://blog.csdn.net/qq_37525899/article/details/81132069

在不破壞結構的狀態下 進行後端移植table

觀察官方 預設返回的結構後

需要注意一點 ，在 List 的 變數 需要 在 初始化 的時候指定為

 new ArrayList<>()

https://stackoverflow.com/questions/43705582/java-lang-unsupportedoperationexception-adding-to-a-list

然後 就是 編寫 java object to json 的寫法

收工 ， 接下來要詳細針對 個別控件 透過 vue routuer 進行傳值的詳細分析，預計大概五天
