Grails remote control plugin - Spring Security Configuration

Question

Whenever I try to use the Grails Remote Control plugin, I get the following Exception.

groovyx.remote.RemoteControlException: Error sending command chain to 'http://localhost:8080/******/grails-remote-control'
    [test] at groovyx.remote.transport.http.HttpTransport.send(HttpTransport.groovy:65)

A simple Google search reveals that it is most likely due to a conflict with the Spring Security plugin. You can see it here. Unfortunately, I cannot find any information on how to properly configure it without going deep into the Spring Security plugin documentation.

How do I configure the spring security core to permitAll for the grails-remote-control url?

Answer 1

Put Below code in your config.groovy

grails.plugin.springsecurity.securityConfigType = 'InterceptUrlMap'

grails.plugin.springsecurity.interceptUrlMap = [
        '/grails-remote-control/**':       ['IS_AUTHENTICATED_ANONYMOUSLY']
]

Answer 2

If you are using spring security 2 with staticRules + controllerAnnotations, it also works:

grails.plugin.springsecurity.controllerAnnotations.staticRules = [
        '/grails-remote-control/**': ["permitAll"]
]
