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;
}
}
