How to get the global (company) group id in Liferay without accessing ThemeDisplay?

P.S.: with ThemeDisplay it is simple: themeDisplay.getCompanyGroupId().

回答1:

When you have only one Company in your portal:

Company company = CompanyLocalServiceUtil.getCompanyByMx(PropsUtil.get(PropsKeys.COMPANY_DEFAULT_WEB_ID));
long globalGroupId = company.getGroup().getGroupId();

Extending yellow's answer, you can find the company if you know some value of the Portal Instance (Company):

1. If you know the webId of the Portal Instance, can find company by:

   String webId = "liferay.com"; // PropsUtil.get(PropsKeys.COMPANY_DEFAULT_WEB_ID)
   Company company = CompanyLocalServiceUtil.getCompanyByWebId(webId);
   long globalGroupId = company.getGroup().getGroupId();
   

2. If you know the mail-domain of the Portal Instance, can find company by:

   String mailDomain = "liferay.com";
   Company company = CompanyLocalServiceUtil.getCompanyByMx(mailDomain);
   long globalGroupId = company.getGroup().getGroupId();
   

3. If you know the virtual host of the Portal Instance, can find company by:

   String virtualHost = "localhost";
   Company company = CompanyLocalServiceUtil.getCompanyByVirtualHost(virtualHost);
   long globalGroupId = company.getGroup().getGroupId();
   

_{There are also other useful methods available to explore in CompanyLocalServiceUtil, for those who are interested.}

Thanks Yellow for the lead, it was really helpful.

You can use the following :

GroupLocalServiceUtil.getCompanyGroup(PortalUtil.getDefaultCompanyId()).getGroupId();

If you need this info for Document Library, you can use

public static long getDefaultCompanyId(){
        long companyId = 0;
        try{ companyId = getDefaultCompany().getCompanyId(); }
        catch(Exception e){ System.out.println(e.getClass() + " " +e.getMessage()); }
       return companyId;
}

public static long getDefaultGroupId (){

    long companyId = getDefaultCompanyId();
    long globalGroupId = 0L;

    Group group = null;
    try {
        group = GroupLocalServiceUtil.getGroup(companyId, "Guest");
    } catch (PortalException | SystemException e) {
        e.printStackTrace();
        return globalGroupId;
    }
     globalGroupId = group.getGroupId();


    return globalGroupId;
}
