Grails: disable Spring Security Core on certain paths


How do I set up Spring Security Core in a way that calls to a certain pattern (such as /api/**) are not filtered?

grails.plugins.springsecurity.filterChain.chainMap = [
'/api/**': '',
'/**': 'JOINED_FILTERS',
]

doesn't work, since it will try to resolve the bean ''.

Is there anything other than the nasty workaround with 'JOINED_FILTERS,-filter1,-filter2,...'

How are static resources being excluded from Spring Security?


Solution

  • You need to add the anonymous filter to your filter chain. If you followed the grails spring security rest configuration tutorial you probably got the following code:

    grails.plugin.springsecurity.filterChain.chainMap = [
        //Stateless chain
        [
            pattern: '/**',
            filters: 'JOINED_FILTERS,-anonymousAuthenticationFilter,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter,-rememberMeAuthenticationFilter'
        ]
    ]
    

    Note that you have "-anonymousAuthenticationFilter" , which removes this filter from your filter chain. By removing this part (-anonymousAuthenticationFilter) from your code, this filter will back to your filter chain, so you can use the @Secured("permitAll") or @Secured(['IS_AUTHENTICATED_ANONYMOUSLY']) again.

    My final filter chain map was the following and worked like a charm.

    grails.plugin.springsecurity.filterChain.chainMap = [
        //Stateless chain
        [
            pattern: '/**',
            filters: 'JOINED_FILTERS,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter,-rememberMeAuthenticationFilter'
        ]
    ]
    

    Add this to you logback.groovy in the development environment when you need to see more details about the authentication process

    logger("org.springframework.security", DEBUG, ['STDOUT'], false)
    logger("grails.plugin.springsecurity", DEBUG, ['STDOUT'], false)
    logger("org.pac4j", DEBUG, ['STDOUT'], false)
    
    logger("StackTrace", ERROR, ['FULL_STACKTRACE'], false)
    root(ERROR, ['STDOUT', 'FULL_STACKTRACE'])
    

    The same idea applies if you do not use spring security rest.
