This is a Java controller class that handles requests related to a forum. It has two methods: "page" and "list".

The "page" method handles requests for the backend list of forums. It takes in a map of parameters, a ForumEntity object, and a HttpServletRequest object as parameters. If the user making the request is not an administrator, it sets the user ID of the forum to the ID of the current user session. It then creates an EntityWrapper object and uses it to query the database for forums. It returns a R object with the queried forums as data.

The "list" method handles requests for the frontend list of forums. It has the same parameters and functionality as the "page" method
