Grails 2.5 & SpringAcl：aclCacheManager bean 不可访问

Question

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 是这样设置的：

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：

我刚刚在尝试从 grails 2.4.3 -> 2.5.0 升级时遇到了同样的问题。

我认为问题源于新的 Hibernate/Cache 插件创建 CacheManager 的方式发生了变化。从讨论here、here 和here 来看，看起来较新的版本（即在 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 spring-security-acl 插件将无法创建 Hibernate CacheManager 后创建自己的管理器。

我原以为命名 hibernate CacheManager 可以解决这个问题（就像你已经做过的那样），但没有骰子。

我的临时（未经测试）解决方法是将以下内容添加到我的应用程序的 resources.groovy：

 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，但我现在对缓存并不太在意，所以只要我的应用程序正在运行我就很高兴。

试试看，看看效果如何。
