(Quick Reference) # filters ## Purpose The `filters` plugin configures Grails' support for Filters. ## Examples An example filter:
    class SecurityFilters {
        def filters = {
            loginCheck(controller: '*', action: '*') {
                before = {
                    if (!session.user && !actionName.equals('login')) {
                        redirect(action: 'login')
                        return false
                    }
                }
            }
        }
    }
Filter rule attributes: `controller` - controller matching pattern, by default * is replaced with .* and a regex is compiled `action` - action matching pattern, by default * is replaced with .* and a regex is compiled `regex` (`true`/`false`) - use regex syntax (don't replace '*' with '.*') `find` (`true`/`false`) - rule matches with partial match (see `java.util.regex.Matcher.find()`) `invert` (`true`/`false`) - invert the rule (NOT rule) ## Description Refer to the section on Filters in the Grails user guide which details how filters work. Configured Spring Beans: `filterInterceptor` - An instance of CompositeInterceptor that composes all the filters together into a single Spring `Interceptor`. Configured Spring Beans given a filter called `SecurityFilters`: `SecurityFiltersClass` - The GrailsFiltersClass instance which aids in analyzing the conventions within the filter. `SecurityFilters` - A singleton reference to the filter itself to support auto-wiring into a Filter | Quick Reference (hide)
