如何在MySQL中显示类别并将其添加到现有子类别中？

Question

此刻我的程序按以下顺序工作：

  

类别<菜单<菜单详细信息

我需要拥有：

  

类别1 <类别<菜单<菜单详细

我一经尝试，就发现只有@PreAuthorize("hasAnyAuthority('permission1','permission2')")被打开，并且在Category1中单击Category_name1中的任何INSERT INTO之后，要么所有类别或其他类别已打开。

事实证明，Category1看不到它无法识别点击，只打开了Category1上所有点击中的全部或某物

这是我的数据库表：

Category1

这是用于将程序与数据库同步的Category API.php代码：
