어떤 플러그인을 사용하고 있습니까? Grails 2.4.3으로 업그레이드 할 때 동일한 예외가 발생하고 Grails WebFlow 플러그인과 ACL 플러그인 모두 expressionParser라는 빈을 설정했지만 각 플러그인은 다른 클래스 ... 스프링 빈의 Grails 초기화 중 다른 클래스를 덮어 씁니다. WebFlowPluginSupport.groovy 파일에서 웹 플로우 플러그인의 expressionParser를 flowExpressionParser로 바꾸면이 예외를 피할 수있었습니다. plugins 디렉토리에서 'expressionParser'를 검색하여 플러그인을 사용하고 있는지 확인하십시오.

저는 webflow 플러그인 사람들에게 알려주고, 여기에 좀 더 자세히 설명합니다. https://jira.grails.org/browse/GPWEBFLOW-109
