我想使用Spring Security ACL plugin。我遵循了官方文档中的教程：http://grails-plugins.github.io/grails-spring-security-acl/docs/manual/guide/tutorial.html
运行示例时出现以下错误：
Configuring Spring Security Core ...
... finished configuring Spring Security Core
Configuring Spring Security ACL ...
... finished configuring Spring Security ACL

导致此错误的原因是什么？
答案 0 :(得分：3)
尝试按照以下解释：http://markushanses.blogspot.fr/2015/06/grails-250-mit-spring-security-acl.html
基本上，你需要添加你的resources.groovy文件：
import org.springframework.cache.ehcache.EhCacheManagerFactoryBean
beans = {
aclCacheManager(EhCacheManagerFactoryBean) {
shared = true
}
}
