The STRUTS2 project uses the IF tag of struts to determine the session, so that users who are not logged on cannot see the page, but this is now only in the view layer, if the user is not logged in directly in the Address bar to enter the address of the logged in user to access, Then the corresponding action will be executed, just do not let the user see it. This is obviously not good, so we have studied the authorization of Struts2. The core of the authority is the business logic, which is much
