Question

我已在Liferay 7门户网站中为Organization创建了自定义字段。现在我想获得自定义字段的值并获取PrincipalException - PermissionChecker未初始化：

    Long userId = (Long) req.getSession().getAttribute(WebKeys.USER_ID);
    List<Organization> mylist = OrganizationLocalServiceUtil.getUserOrganizations(userId);
    if (!mylist.isEmpty()) {

        Organization organization = mylist.get(0);

        String orgUrl = group.getFriendlyURL();

>>>     ExpandoBridge expandoBridge = organization.getExpandoBridge();
        System.out.println(expandoBridge.getAttribute("custom_field"));
    }

例外：

Caused by: com.liferay.portal.kernel.security.auth.PrincipalException: PermissionChecker not initialized

收到同事的答复。现在它正在运作。将guest字符的权限设置为true并添加此代码

        protected void exportexcelmail_Click(object sender, EventArgs e)
    {


        DataTable dt = new DataTable();
        DataBaseConnector db = new DataBaseConnector("M");
        var masterid = Request.Form["MasterID"];

        try
        {

            db.Connect();
            db.InitCommand();
            db.SetSqlString(Procedures.ReportsCustomerEmail.ToString());
            db.AddParameter("@aysid", masterid);
            dt = db.ExecWithTable();
            db.Close();


            MyFunction.ExportExcel_Click(dt, "MyExcel");
        }

         catch (ThreadAbortException exp)
        {

                    //THAT is OK.Page never Refresh 

        }


        catch (SqlException exp)
        {

            if (db != null)
            {
                db.Close();
            }


             string script = "<script type=\"text/javascript\">alert('" + exp.Message.Replace("'", "") + "');</script>";
             ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script);
             //PAGE REFRESH HERE
        }



        catch (Exception exp)
        {

            if (db != null)
            {
                db.Close();
            }
             string script = "<script type=\"text/javascript\">alert('" + exp.Message.Replace("'", "") + "');</script>";
            ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script);





        }
