1. 权限校验action
public class CheckPrivilegeAction extends Action{ public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) { PrivilegeForm pf = (PrivilegeForm) form; response.setContentType("text/json;charset=utf-8"); List<String> urls = new ArrayList<String>(); JSONArray json = null; try { urls = JMongoDB.getUserPrivilegeList(pf.getUid(),true); json = JSONArray.fromObject(urls); PrintWriter out = response.getWriter(); System.out.println(json); out.print(json); out.flush(); } catch (Exception e) { e.printStackTrace(); } return null; } }
2. 权限管理页面
