Groovy Script Method to Delete Users in Bulk

Issue

• I need to delete many users at once from a Liferay instance in a programmatic and efficient way without directly modifying the database (which is not advised).

Environment

• DXP 7.1

Resolution

• Below is a template groovy script utilizing actionable dynamic queries to delete users in bulk.

Please Note:  The below script is again only a template that is meant to serve as a starting place to go off and develop your own custom script utilizing a delete method at your team's discretion.

import com.liferay.portal.kernel.dao.orm.ActionableDynamicQuery;
import com.liferay.portal.kernel.service.UserLocalServiceUtil;
import com.liferay.portal.kernel.model.User;

ActionableDynamicQuery adq = UserLocalServiceUtil.getActionableDynamicQuery();

adq.setPerformActionMethod(new ActionableDynamicQuery.PerformActionMethod<User>() {

    @Override
    public void performAction(User user) {
      out.println(user);
    }

});

try {
    adq.performActions();
}
catch (Exception e) {
    e.printStackTrace();
}

• Additionally, it is recommended to test your script in a lower environment and then backup your database before running in production.
