How to check user authority or permission in Java Code ? For example - I want to show or hide button for user depending on role. There are annotations like:
@PreAuthorize("hasRole('ROLE_USER')")
How to make it in Java code? Something like :
if(somethingHere.hasRole("ROLE_MANAGER")) {
layout.addComponent(new Button("Edit users"));
}
you can use the isUserInRole method of the HttpServletRequest object.
something like:
public String createForm(HttpSession session, HttpServletRequest request, ModelMap modelMap) {
if (request.isUserInRole("ROLE_ADMIN")) {
// code here
}
}
