从2.4.x迁移到最新的2.5.0版本后，我更改了数据源中休眠的一些参数:
cache.region.factory_class =
'org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory'
和Config.groovy:
grails.cache.enabled = true
grails.cache.clearAtStartup = true
grails.hibernate.cache.queries = false
beans.cacheManager.cacheManagerName = 'springcacheCacheManager'
beans.cacheManager.shared = true
在resources.groovy中，ehcache bean的设置如下:
ehcache(EhCacheFactoryBean) { bean ->
cacheManager = ref("springcacheCacheManager")
cacheName = "cache"
eternal = false
shared = true
diskPersistent = false
memoryStoreEvictionPolicy = "LRU"
maxEntriesLocalHeap = "10000"
timeToIdleSeconds = "120"
timeToLiveSeconds = "120"
maxEntriesLocalDisk = "10000000"
diskExpiryThreadIntervalSeconds = "120"
}
然后，带有aclCacheManager的springAclService的问题出现在 bootstrap 中:

最佳答案
我刚遇到尝试从grails 2.4.3-> 2.5.0升级的相同问题。
我认为问题源于新的Hibernate / Cache插件创建CacheManager的方式发生了变化。从here，here和here的讨论来看，似乎较新的版本(即grails 2.5.0中使用的版本)不允许多个未命名的缓存管理器，因此，一旦在Windows Server 2003上创建了spring-security-acl插件，它将无法创建自己的管理器。 Hibernate CacheManager已创建。
我本以为命名休眠的CacheManager可以解决此问题(就像您已经做过的一样)，但是没有骰子。
我的临时(未试用)解决方法是将以下内容添加到应用程序的resources.groovy中:
aclCacheManager(org.springframework.cache.ehcache.EhCacheManagerFactoryBean) {
shared = true
}
我实际上不知道这是否意味着ACL插件现在将与Hibernate共享相同的缓存管理器，但是我现在对缓存不感到困惑，因此只要我的应用程序正在运行，我就很高兴。
试试看，看看你如何过。
