把它放在你的 config.groovy 中:
grails.plugins.dynamicController.mixins = [
'com.burtbeckwith.grails.plugins.appinfo.IndexControllerMixin': 'com.burtbeckwith.appinfo_test.AdminManageController',
'com.burtbeckwith.grails.plugins.appinfo.HibernateControllerMixin': 'com.burtbeckwith.appinfo_test.AdminManageController',
'com.burtbeckwith.grails.plugins.appinfo.Log4jControllerMixin' : 'com.burtbeckwith.appinfo_test.AdminManageController',
'com.burtbeckwith.grails.plugins.appinfo.SpringControllerMixin' : 'com.burtbeckwith.appinfo_test.AdminManageController',
'com.burtbeckwith.grails.plugins.appinfo.MemoryControllerMixin' : 'com.burtbeckwith.appinfo_test.AdminManageController',
'com.burtbeckwith.grails.plugins.appinfo.PropertiesControllerMixin' : 'com.burtbeckwith.appinfo_test.AdminManageController',
'com.burtbeckwith.grails.plugins.appinfo.ScopesControllerMixin' : 'com.burtbeckwith.appinfo_test.AdminManageController',
'com.burtbeckwith.grails.plugins.appinfo.ThreadsControllerMixin' : 'com.burtbeckwith.appinfo_test.AdminManageController'
