Question

I have a grails 2.1.0 application with Spring Security Core and Multi-tenant single db plugin working fine. One of the requirements for this application is to limit concurrent logins to just one. For this, I’m trying to use SpringSecurityUtils in Bootstrap to register a filter.

 SpringSecurityUtils.clientRegisterFilter('concurrencyFilter', SecurityFilterPosition.CONCURRENT_SESSION_FILTER)

SpringSecurityUtils is static and as the documentation says, need not be injected, but on executing, it errors out

ERROR context.GrailsContextLoader  - Error executing bootstraps: No such property: SpringSecurityUtils for class: BootStrap

Message: No such property: SpringSecurityUtils for class: BootStrap
Line | Method
->> 17 | doCall in BootStrap$_closure1

Spring security is otherwise working fine.

Any help is much appreciated.

You’re missing the import – add

import org.codehaus.groovy.grails.plugins.springsecurity.SpringSecurityUtils

and it looks like you’ll need this too:

import org.codehaus.groovy.grails.plugins.springsecurity.SecurityFilterPosition
