java programmers use the project Ant Financial Services Group ant design pro ((hereinafter referred to as pro). Everyone who has used it knows that the menu of the original pro project is defined by a file. I would like to ask how to load the menu json from the database to the route after logging in. Is after logging in to get the json do not know how to load the route, another question is that the permission authentication of the pro project can contain multiple roles in one menu?
